A new solar cell was successfully developed

March 3, 2010 No comments »

California Institute of Technology recently developed a new solar xps m1330 battery , whose basic principle is that the thin silicon line array embedded in the polymer substrate. In addition to thin flexible things, its absorption of sunlight and the photoelectric conversion efficiency have made significant breakthroughs. In addition, traditional solar cells required for the amount of expensive semiconductor material ,compared to traditional solar cells ,this new type of solar cells need only a small part.

Applied physics and materials science professor Harry Atwater and Howard Hughes, said: “These solar cells (take the inspiron e1505 battery for example )broken through the traditional materials of light absorption to capture the limit for the first time.” New type of silicon used solar cell arrays on a single line of the incident light wavelength, the absorption rate is up to 96% ,for the full wavelength to capture the sun can reach 85%.

Atwater said: “A lot of the materials is able y to capture light very well, but it can not be converted into electrical energy, such as black paint. For the solar inspiron 1520 battery , the absorbed photon is converted to electrical load can the child (charge carrier) is also very important.” and their R & D line array of silicon solar cells can be absorbed by the photon 90-100% converted to electronic. Technically, this array has a near-perfect internal quantum efficiency (internal quantum efficiency).

Atwater concluded: “The high light absorption and better conversion of competence achieved this high-quality solar cell for np-100 .”

Length of Silicon wire arrays in silicon line is 30 to 100 microns (micron) between the diameter of only 1 micron. The thickness of the entire array is equivalent to the length of the silicon lines, but from the corner of the area or volume of view, only 2% of this material is silicon, the other 98% of all polymers. As silicon is very expensive ingredients in the traditional solar cells,like the compaq presario v6000 akku . so this will be much lower,which only require1 / 50 traditional amount of the the cost of solar cell production.

Note the use of lithium battery

February 24, 2010 No comments »

Some people might be familiar to lithium batteries from mobile phones,such as Sony np-qm91 . In fact, it is being used in many household appliances. Needless to say, lithium battery is efficient, lightweight, and so its benefits are opened and promoted to use rapidly. But, you know, use carelessly, it will make you provoke “fire” upper to your body?

Lithium batteries have a body of light, high efficiency,like the Fujifilm np-40 battery low temperature (-40 ℃) etc., 0.3mm thick, stamp-sized lithium battery can be used continuously for more than five years, in recent years are being phased out are used in alkaline batteries and manganese batteries, widely used in many high-end home appliances and mobile handsets.

Unlike alkaline manganese dry battery of the zinc chloride and potassium hydroxide aqueous electrolyte, Lithium batterie uses an organic solvent. Lithium Battery Cathode use manganese dioxide, lead fluoride, thionyl chloride and other materials. Anode used lithium metal foil anode ,compared with the general use of zinc chloride batteries, take the Dell inspiron 1520 battery for example ,ionization tendency is strong, and positive and negative voltage difference is big, so that improving the effectiveness of lithium batteries.

However, there are fever and burning phenomenon in the using course of lithium batteries often , it have the light impact to the host, in serious cases ,it will also cause a fire burned down the host. It is reported that Japan has in recent years there were several causes of Li-ion battery heat caused by the family fires burning.

So why lithium batteries can cause fever and burning? after many of the original lithium battery materials contact with water,for one thing ,the Nikon en-el8 battery ,severe chemical reaction can occur, and release a lot of heat leading to fever, burning phenomenon. Manganese dioxide lithium battery cathode only contact with a small drip ,it can dip fever phenomenon. Lithium thionyl chloride batteries contact with water in the generation of hydrochloric acid and sulfur dioxide, while the release of heat, several factors make life lithium batteries to become the “fire” ,and therefore people must pay attention to water-proof, anti – wet when using lithium batteries . A variety of host are disabled, they should remove the batteries, and placed them in dry, low temperature at the proper custody, to prevent and avoid battery fires and household accidents ,due to inappropriate use of lithium battery for Nikon en-el4 .

The correct use of mobile phone batteries methods

February 21, 2010 No comments »

In the course of normal use of mobile phones, we should pay attention to the following areas.

  1. Do not covet a small cheap, cheap no good merchandise, do not believe something so cheap, any product prices is decided by its cost, ,such as Dell inspiron 600m battery , if the product is lower than the basic cost of the things ,that can not be bought.
  2. Try to use original battery

    3. Using the original Panasonic cgr-s003 battery is guaranteed its own security the most important one. It is understood that in the past few years, there were already dozens of mobile phone battery explosion, triggered the explosion that was not original equipment batteries.

  3. Do not try to modified Dell inspiron 6000 battery phone

    4. A large number of fashionable young people like to transform your mobile phone into their preferred appearance, but industry insiders say they can easily lead to improper modification phone explosion. As the mobile phone version is a sophisticated communications equipment, in the design, manufacturers will have on its strict security research, Dell inspiron 510m battery performance is the best, but when modified, all this will change, easily lead to explosion of mobile phones.

  4. As far as possible using the original charger

    5. Original battery charger can guarantee safety. Although it is compatible charger can also be used, but some have also electrically unqualified, will damage the Casio np-60 battery, and cause an explosion.

  5. Do not put the battery under high temperature environment

    6. Higher temperatures will cause the battery to increase the heat, when most prone to explosion, so we put the battery for Casio np-30 charger or cell phone, be sure to choose a place away from heat, while avoiding direct sunlight during summer months. The accident was caused by mobile phone users use mobile phones at high temperatures.

  6. do not use damaged batteries

    7. An explosion damaged the Sony np-fh100 battery easily, even if it is not an explosion will damage the device, resulting in cell phone short-circuit inside the device, so do not use damaged batteries can also be guaranteed its own security.

The method of preventing mobile explosion:

  1. To avoid prolonged mobile phone calls. Long talk time, mobile phone batteries will not only result in fever, but also result in phone’s internal circuitry of fever, so easy to cause an explosion.
  2. Try not to call charging. When charging the phone Samsung sb-l160 battery will produce heat, then continue to use it to call, the temperature will quickly increase, it is prone to lead to danger.
  3. Do not phone hung on the chest. Phone hung on the chest, once the phone fried would directly harm the chest and face. The incident is the mobile phone users a mobile phone pocket on the chest triggered.
  4. Do not try to put trouser pocket inside apple a1045 phone. If an explosion occurred, cell phones can be placed in carry-on bag to reduce the harm caused to the user.
  5. Multi-use headset to answer the call, it is best Bluetooth headset. Headset to answer the call because it reduced the radiation, because of its wireless Bluetooth headset features safer. If the case of mobile phone Dell inspiron 5100 battery explosion, it can avoid facial injury.

Batteries: This is the most commonly used type of battery,such as Canon bp-2l12 . In general we are also known as zinc-manganese dry batteries

commonly used in batteries. Can be divided into carbon-zinc batteries (Carbon-Zinc) and zinc chloride batteries (Zinc-Chloride), the advantage of a higher energy density, current density, appropriate, easy to mechanized production. In

the supermarkets in these two types of batteries into a box into the box in order to lower the price of the auction. But unfortunately due to lack of energy density is generally used only for the Casio np-100 battery power small electronic products, such as: alarm clock, calculator and so on. If you intend to use him to drive your digital camera I am afraid you will be disappointed.

Cylinder-type zinc-manganese vostro 1500 battery can be divided into cardboard paste-type zinc-manganese batteries and zinc-manganese batteries,due

to the difference between isolated objects. One board composed of zinc-manganese batteries due to differences in formulations of different electrical properties caused further divided into the C-board batteries (carbon-zinc batteries),

also known as high-capacity battery; P-type cardboard battery (Zinc Chloride akku ), also known as high-power battery. General supermarkets or retail markets dry Jiewei such batteries, its

marked as Super Heavy Duty. “C”-type power capacity than the “P”-type cells by about 20%, generally accompanying a gift for such multi-cell batteries, dry xps m1330 battery into the packaging carton ( “C” type commonly used), PVC, steel, and lead sheet and other four categories of packaging, while according to the amount of mercury

(basic standard of 15ppm) to distinguish between environmental and non-environmental protection are different.

Alkaline Zinc – Manganese Battery (Zinc-MnO2): isan important role in dry battery ,take the Canon nb-71 for example . This type of battery is what

we often call the “alkaline batteries”, due to large capacitance, current use has strong and lasting, the market on the growing demand for such batteries. However, some manufacturers of alkaline batteries environmentally-

friendly non-mercury batteries, because such a cell, such as silver oxide in the ingredients can be added to enhance its capacitance is about 30%, while the retail price increases. To date, the alkaline Jvc bn-vf823,battery is the most successful high-capacity battery, the battery is currently the most cost effective one, it has changed the internal structure of traditional

batteries and electrochemical systems, with excessive use of very pure very active in positive and negative materials , and its discharge capacity of 5-7 times that of ordinary dry batteries, storage, life expectancy more than twice the

normal battery. On the other hand, alkaline batteries for Samsung sb-l320 , but also because it is a perfect discharge curve and the acclaimed,

especially for the need for sustained high-current discharge of the occasion, such as cameras, electric toys, BP machine, WALKMAN, electric razor and so on.

The method of extending battery life

February 7, 2010 No comments »

There are many different kinds for laptop Sony np-fh30 battery, of course, the nature of different types of batteries will not be the same. Now widespread notebook computer used lithium-ion batteries (or similar products); shortly before a computer, A4-based notebook computer under the premise of the use of temporary use of nickel-metal hydride batteries; while until the mid-nineties, using a nickel-cadmium battery. After the user to buy a notebook, first of all look at operating instructions, to confirm what kind of battery is used. If there is no manual you can view the laptop battery manufacturer’s home page specification.

The biggest problem of nickel-metal hydride Sony np-qm71d batteries and nickel-cadmium batteries is the “memory effect”, if the battery has not run out on the charge (half-way charge), then next time you use the battery when the charge used in the beginning there is no electricity in that place. If the constant cycle of a process, the battery life will be shorter and shorter.

Although the Ni-MH battery for Casio np-30 memory effect is smaller than nickel-cadmium batteries, but also shorten the life of repeated half-way charging the reasons, so please try to recharge after the battery fully utilized.Lithium-ion battery without memory effect, so even a half-way off and there will not be charging a big problem.

The method of extending battery life:

Although the lithium-ion battery without memory effect, but the incorrect use will greatly affect the life span. The use of lithium-ion battery should pay attention to the following points:

  1. Not to use AC power | Regulators Driver for full power

    2. Compared with no full power, full power state more easily aging. In particular, the use of AC is full of electric power-driven, the ,Fujifilm np-120 battery will bring a heavy burden. It also increases the amount of heat, to further accelerate the aging batteries. Therefore, the temporary use of laptop computers, once filled with electricity, a good idea to use battery power. Manufacturer recommends the use of AC power when you remove the battery (remove the akku , but if we must pay attention to unplug the occurrence of accidents such as power outages or cable, it will not keep losing the data).

  2. Use power-saving features

    3. The factors that affect the Nikon en-el8 battery life is the charge and discharge cycles. In order to minimize the frequency of recharging, we can use laptop computers with power saving function (when using battery-powered, dimming the screen brightness, reducing CPU speed to reduce power consumption). By the same token, the battery there is electricity, it is best to try not to charge the battery fully utilized.

  3. Fully discharge once every other months,

    4. Another trick is to put each or a few months once the battery ,Jvc bn-vf808 is fully discharged. A specific approach is to have zero power to the battery used to power after the zero to stop using, connect AC adapter, and then do not use personal computers, at a stretch to full power. Some personal computers have a “battery discharge (BatteryRefresh) function.” If we think that the battery is very easy to use, you can try using the battery discharge feature.

  4. It not is used for
    a long time when, unplug the AC adapter

    5. More than eight hours or more when not in use, in order not to burden the Canon bp-911 battery, please unplug the AC adapter. Also, if more than a month when not in use, please remove the battery from the machine and placed in the shade.

  5. When to replace the battery?

    6. The standard is to replace the battery for Casio np-100 charge can only achieve the original capacity of 6 percent or so. Because there are many types of cells, it is necessary to purchase personal computers being used on that kind of model. In addition, it is best not to pre-purchase of spare, because if not, the battery will be natural wear and tear.

There has been no need to buy genuine batteries, but to discharge the battery currently in use in order to restore the performance of services. “BAYSUN” is one of them a week’s time to restore the battery performance.

This approach not only cheap, compared with the purchase of authentic, there is no inventory in the factory, or second-hand laptop with the ,Nikon en-el3 battery can no longer use such occasions are particularly convenient.

The fuel cell vehicle technology has made great progress

February 1, 2010 No comments »

With the support from governments ,major automotive companies have developed fuel xps m1710 battery vehicle research and development programs, General Motors, DaimlerChrysler, Toyota, Honda and other auto companies have developed fuel cell vehicles and investment in pilot operation. Meanwhile, the international energy giant BP, Shell, also established a hydrogen energy research in support of hydrogen energy research and related activities.
Through the tireless efforts of governments and relevant enterprises, the fuel cells vehicle technology has made great progress, mainly in the following five aspects:

  1. Fuel cell power density continuously improve the development of Canada’s Ballard’s 2003 fuel Samsung sb-l480 cell engine XcellsisHY80 used 902 balls, maximum output power of 68kW, the volume of 220L, the quality of 220kg, the volume and qualityof the power density of 309W / L and 309W/kg, has been basically reached the United States Department of Energy’s FreedomCAR plan proposed by the 2010 target.
  2. Precious metals substantially reduced amount of platinum fuel vostro 1500 battery stack usage from about 1990 to about 5mg/cm2 down to 0.5mg/cm2, and is expected to continue to reduce.
  3. The energy conversion efficiency of fuel cell vehicles is expected to continue to improve the consideration “from the mine to the wheel,” the overall efficiency, fuel cell hybrid electric vehicle “from the well-to-wheel,” the overall efficiency of 29%, gasoline engine hybrid electric vehicle Prius overall efficiency of 28%. Fuel Dell xps m1330 battery vehicles in the future the overall efficiency of energy conversion is expected to increase 42%.
  4. Fuel cell for Fujifilm np-95 vehicles marked improvement in the reliability and durability, such as DaimlerChrysler and General Motors Corp. test run showed that the reliability of fuel cell vehicles has significantly improved the company’s fuel cellvehicles have been carried out parcel courier services.
  5. Decreasing the cost of the fuel cell system by high-volume production, if (an annual output of 1.5 million units) calculated in 2002 the price of the fuel cell ,Samsung sb-lsm320 engine 275 U.S. dollars / kW, 2006 it had dropped to 110 U.S. dollars /kW.

The proper use and maintenance of batteries

January 25, 2010 No comments »

Maintenance-free rechargeable xps m1730 battery can also be added, charging an ordinary battery charging method essentially is same. Every single cell charging voltage should be limited to between 2.3-2.4V. Note that using conventional charging methods, charging will consume more water, when charging ,the charge current should be smaller more (5A below). battery can not be fast charged, otherwise the JVC BN-V428 battery may be an explosion, resulting in injury. When the maintenance-free battery hydrometer shown as yellow or red, it stated that the battery is nearing end of life, even if the re-charging, life is not long.

the right maintenance-free batteries can be used with the current – voltage characteristics of the charging device to recharge for battery. The device can ensure adequate power, and avoid over charging and consumption of more water.

The proper use and maintenance of batteries have the following 7 points:

  1. check the battery in a fixed bracket on the bolt is tightened or not , due to shell damage,if the installation will be insecure,it can cause road vibration. Also do not put metal on the battery,KONICA MINOLTA NP-600 to prevent short circuits.
  2. often see the first pole and the wiring connections have is reliable. To prevent the terminal oxidation, can coat Vaseline or other protective agents.
  3. do not using direct ignition (short-circuit test) method tp check the battery for Canon NB-4L power so battery damage.
  4. ordinary lead-acid batteries should pay attention to adding distilled water. it is best to charge for Dry-charged battery prior to use. As for the water to maintenance-free KONICA MINOLTA NP-400 batteries can be able to maintain an appropriate view if necessary,it is helpful for adding distilled water to prolong life .
  5. battery cover of the pores should be smooth. Battery charging will produce a large number of air bubbles, if the vent is blocked so that gas can not escape ,when the pressure increases to a certain degree ,battery will result in the shell burst.
  6. due to sulfuric acid corrosion of the root column, line cards, there will be yellow-white paste in the Sony NP-QM71Dbattery very often around the column and cap. Great resistance of these substances must be promptly removed.
  7. when it need to use two batteries in series ,the same xps m1330 battery capacity is best. Otherwise it may affect battery life.

The general type of maintenance-free batteries for Minolta NP-200 can be kept from the factory to the use of 10 months, its voltage and capacitance remain unchanged,after 3 months the voltage and capacitance of the poor quality will drop. The time of purchase date of the election away from the production is 3 months, we can check the battery voltage and capacitance whether the statement on the requirements on the spot , if the voltage and capacitance are declining ,it showed that inside the material is not good, then the battery Quality certainly is not OK, it may be adding water to the xps m1530 battery charge through the dealer made of camouflage.

Types of solar cells and solar cells

January 22, 2010 No comments »

Solar xps m1730 battery is a device for human to use solar energy, which is to make sunlight directly converted into electricity by using photovoltaic effects , and only when the sunlight the power generation, therefore, we can store electricity.

At present, we usuallly used the silicon as a kind of photoelectric Sony NP-FC11 cell , and its photoelectric conversion efficiency is up to 11% ~ 14%. In addition,there are CdS cells, cadmium telluride batteries. The use of solar cell devices has been increasing, such as electronic calculators, tape recorders and so on, the price of commercial solar cells has dropped to below 4 U.S. dollars per watt. The application of solar cells are increasingly ,The application of solar xps m1330 battery are increasingly being used ,prospects are more promising.we pay more universal attention to using solar energy research,such as Solar cars, solar cell generation,and is the focus of future development directionfield of energy in some countries . Some experts predict that solar cell will become the an important source of electricity in 21st century.

There are several varieties of solar Nikon EN-EL3 cell ,they are : amorphous silicon single-crystal silicon, multi-crystalline silicon three categories, while the applications currently on the market are mostly single-crystal silicon and amorphous silicon.

  1. Single-crystal silicon solar cell

    2. &The most common single-crystal silicon xps m1530 battery
    are used for power plants, charging systems, etc.it issued by the wide range of power and voltage conversion, high efficiency, long service life, the world’s major makers, such as Germany’s Siemens, British Petroleum and Japan are Sharp Corp. the production of such single-crystal silicon solar cell with market share is about 5 into single ,crystal silicon cell efficiency is from 11% ~ 24%, space level (deposition type) chips is from 16% ~ 24%, of course, the higher the efficiency is , the more expensive its price.

  2. Multi-crystalline silicon solar cells

    3. Polysilicon over single crystal silicon Canon BP-511efficiency is low, but relatively process steps is simple , the cost is also low, compared with single-crystal silicon cells it is 20 percent less cheaper, so some low-power applications of electricity are used polysilicon solar cells.

What is the direct methanol fuel cell?

January 18, 2010 No comments »

The so-called direct methanol fuel Nikon EN-EL3cell (Direct Methanol Fuel Cell) belongs to one of the categories of the proton to exchange membrane fuel cell (PEMFC) , see the direct use of aqueous solutions of methanol as fuel and steam supply source, through the restructuring of devices without having to re-methanol, gasoline and and then remove the hydrogen such as natural gas for power generation. Compared to proton exchange membrane fuel cell (PEMFC), direct methanol fuel Canon BP-511 cell (DMFC) low temperature of Health electricity, fuel components and battery  low-risk features such as simple structure, so that direct methanol fuel cell (DMFC) portable electronics applications may be mainstream.

Direct methanol fuel cell is a proton exchange membrane fuel cell forSony NP-FC11 as a variant ,it make use of methanol directly rather to pre-restructuring. Methanol at the anodechange into carbon dioxide, proton and electron, it same as the standard proton exchange membrane fuel cell. protons produce reaction of oxygen through the exchanginh proton membrane and in the cathodeelectrons through the external circuit to reach the cathode, and doing work.

The expectations of the Canon NB-4L battery operating temperature is 120 ℃, it is slightly higher than the standard proton exchange membrane fuel  cells efficiency is about 40%. The disadvantage is that it need more platinum catalyst ,when low-temperature methanol is converted to hydrogen and carbon dioxide than when the conventional proton exchange membrane fuel cells . The use of direct methanol fuel cell for Olympus li-10b technology is still in its early years of development, it has successfully demonstrated can be used as power supply of mobile phones and laptop computers, it also has the potential for a specific end-user to use in the future.
