• How long will the appropriate charge?

The longer the charging time, battery charging and the more feet, the battery more durable, this view is not correct. In fact, the battery capacity is certain,such as the inspiron 6400 battery , after the charger ,full protection of the circuit will be automatically disconnected, but still there will be a very small trickle. Therefore, the correct charge time should be sufficient light from red to green after an hour, the best, This will not only adequate,and will not damage the battery.

However, due to protective measures in the battery charger, rechargeable battery would not be damaged for too long time . But preferably it should not exceed 24 hours.

• How do I save the unused lithium batteries?

Many people think that, as long as the lithium batteries are stored ,they normally can be used later.it is not true. Even without the use of lithium inspiron 6000 battery per day it will discharge according to the ratio of 0.2% -0.3%, and storage for some time, even without recycling, which will be a small part of the permanent loss of capacity. Therefore, the preservation of lithium-ion batteries should not exceed 1 year.

If you have idle battery, the experts recommended storage conditions is the 40% of charge level, storage temperatures is below 15 degrees Celsius or lower. Note, If I have to save the long-term unused batteries, you have to preserve the inspiron 1520 battery after the charging ,but not sufficiently discharge to save, so that the battery can prevent uncontrolled self-excessive discharge in the store.

there are some good advice on the use of mobile phone batteries

• Text messaging is very power

A friend of mine often said, one day I did not make some calls, they just send text messages, cell phone quickly have no electricity. In fact, text messaging is a very power-hungry. you must keep on buttons for writing a message, the background light need to continue to open to open stop-and send on internet, as well as receive.so the extent of the inspiron e1505 battery power will not be much weaker than the phone calls.

However, the most power-hungry is to play machine. At present, some mobile phones go with the radio and MP3 functions, some people have been listening to the long songs by the phone all day,and listen to the radio, the np-100 battery definitely will not last long. Even the more frightening is that mobile phones built-in games are more exciting, and the game is opened to play, and Power as water to flow away.

• No need to over-protect the battery

the frequency of rechargeable lithium vostro 1500 battery in general is 300-500 times (keeping the original capacity of 80%), normal use of life is about 1-2 years. The frequency of replacement is now faster and faster, using a cell phone will not take too long, if a cell phone is equipped with two batteries, then the end of battery life is largely to throw away this phone. Therefore, there is no need for batteries too cherish.

1. As the new energy vehicles has the large market, cost-effective, energy-saving features , it is in the preferred position in low-carbon path.

For China’s low-carbon path,pepole consider a low-carbon economic system development, at this stage to consider the cost of priority, market means the development of low-carbon economy, ,because of its relatively large market,new energy (such as the solar inspiron 6000 battery )automotive industry can drive the upstream and downstream development of the industry and stimulate consumption, but also has energy-saving The economy,it is in a preferred position in the low-carbon path .

2. The new energy vehicles will become a national strategy, national support efforts will exceed the other low-carbon industries.

In March 2010, Development and Reform Commission will be promulgated, "new energy vehicle development program," new energy vehicles will be raised to national strategy, it will be a major opportunity for new energy development,like the solar inspiron 6400 battery . In all low-carbon industries, the importance of new energy vehicles top row, the intensity is expected to exceed state support for solar energy, wind power and other industries.

3. 2011 years of new energy vehicles go up to 50 million units, driving demand is more than 50% cell growth, with the improving of penetration of lithium batteries, in the next three years ,it can maintain 50% annual growth.

Thee amount of car batteries for Sharp md-mt66 is huge, an electric vehicle average use 50 kg of cathode materials, anode materials, 40 kg, 40 kg of electrolyte than 4000 laptops and each car . If the use of vehicles by 20% for lithium batteries (10 million cars) could also contribute 5,000 tons of positive, negative 4,000 tons, 4,000 tons of electrolyte. 2009 domestic demand for 8,000 tons of the electrolyte, only 50% increase in auto demand. With the penetration of lithium batteries will increase, more vehicles to use lithium batteries, the next three years, lithium md-mt831 battery can maintain 50% growth.

4. New energy vehicle development, battery manufacturers can get the largest benefit from it ,vehicle manufacturer was less affected.

2009 national automobile production and sales is 13 million, 500 thousand ,new energy vehicles have little impact on the vehicle. Due to higher prices of new energy vehicles, vehicle lower margin, profit, mainly in the upper reaches of the li-12b battery , electronic control and generator links.

5. Gross margin of lithium batteries is higher, with actual results support, it is more desirable in the concept of new energy.

Gross margin: 30 percent positive and negative 20%, the electrolyte 40%, diaphragm 70%, Lithium hexafluorophosphate 70%.

Companies have considerable profitability. Industry technology changes rapidly, bottlenecks is higher cathode, anode material is in the supply-demand balance, electrolyte membrane is the highest part of technical content , the the product is in short supply ,from comprehensive analysis ,new energy vehicles will give priority to the development in low-carbon economy,compaq presario v3000 akku materials company can get the largest benefit from it ,and they have a genuine performance of battery materials support, and the battery market can maintain three years of continuous growth, and industry has the possibility of explosive development .

According to iSuppli Corporation, thin-film solar cells are rapidly capturing the market share that crystal technology have by 2013,such as Dell latitude d600 battery . the PV part will be more double than the number of watts. solar panels in the global market, the efficiency of thin film will be from 14% in 2008 to 31% by 2013.

“First Solar has a strong proof of the viability of thin-film market(take the Dell inspiron e1505 battery for example )the company jumped the world’s largest manufacturer of solar panels this year, production is more than one billion watts.” ISuppli’s research director GregSheppard said, “At the same time, the company has already reduced per-watt the cost of production down to less than 90 cents a silicon crysta,it l is about half of the module manufacturer. ”

Crystal and thin-film

Most solar panels made from crystalline silicon, using 180-230 micron polysilicon. On the contrary, thin-film panels is made of other materials through the deposition of multi-layer substrate , the thickness is a few microns. The main difference between the two technologies lies in the efficiency and cost of electricity per watt. when thin-film panel convert the sunlight into electricity,the efficience is lower , but its production costs are significantly lower,like the Dell inspiron 6400 battery .

It is noteworthy that the film have a disadvantage in the limited installation space , such as residential roofing. Film installation may need more space to account for 15-40% of the crystalline silicon to achieve the same with the overall system power output. This tends to limit its activities in certain application areas more attractive.

Price comparison

Thin-film modules are expected next year, the average price will drop to 1.40 U.S. dollars, it is lower than in 2009 for 1.70 dollars ,such as Dell inspiron 6000 battery . In 2010 the average price of crystalline silicon panels are expected to fall to 2.00 dollars, 2.50 U.S. dollars this year.

iSuppli Corporation predicts that crystalline silicon will narrow the price gap to a certain extent by 2012 , because its suppliers are financially strong, they continue capital expenditures and technology development ,and has invested heavily in improving production processes.

Variety of thin film technology

Most of these techniques rely on chemical vapor deposition (CVD), or derived from the screen printing process, the layers of material deposited on different substrates, namely glass and various plastics. Some of the recent use of inkjet printing technology, like ways to more quickly deposited materials.

Another factor which promote the accelerated development of thin film technology is the use of materials, some companies provide more production lines, such as Oerlikon, and Centrotherm package,and Sony np-qm91 company.

There are a variety of thin-film photovoltaic technology. They are mostly less than 10% efficiency, although some technology can be efficient through experiments up to the middle class. Some of these technologies are referred to as a single node, using a diode. Recent developments in the use of multiple nodes with each other superimposed together, also known as tandem and three knots, so by using different materials or combinations wider absorption spectrum of knot.

As the environment-friendly vehicles are sought after on a global scale, hybrid and electric cars sells the next few years, the automotive Dell inspiron 6400 battery market is expanding rapidly. “It is envisaged that by 2014, the market size will rapidly expand to 2.25 trillion yen (about 24.8 billion U.S. dollars), is about 215 times in 2008.” This is a professional market research agency Fuji, Japan Economic Research Institute has recently come to statistics.

Compared with traditional vehicles, new energy vehicle technology gap with foreign countries do not, there is the possibility of overtaking bend, more contribute to the relevant enterprises to increase investment in new energy vehicles optimism. Among them, car battery power — lithium-ion Samsung sb-l160 battery is a major R & D related to the preferred target.

It is understood that the current hybrid cars use nickel-metal hydride battery for Samsung sb-l320 technology major, but the nickel-metal hydride battery a number of technical properties such as energy density, charge and discharge speed is close to theoretical limits. The lithium battery has energy density, high-capacity, no memory, etc., are various car makers and battery manufacturers unanimous endorsement of the current national focus on R & D is the lithium-ionSony np-qm71d batteries.

According to the different cathode materials, lithium Canon nb-3l batteries are lithium cobalt oxide, lithium manganese oxide, ternary materials, and four kinds of lithium iron phosphate. Lithium iron phosphate which is the best hybrid vehicle using lithium cathode materials. At present, China’s car prices introduced models in purely electric vehicles, power batteries are lithium batteries, Chery, BYD are using lithium iron phosphate. At present, China mainly depend on production of batteries forCasio np-30 and equipment imports expensive, which is our vehicle development is very unfavorable power batteries, power batteries in mass production, it should be of advanced automation equipment, research top priority. In addition, most of the enterprises of China’s independent power battery research and development, its funding is limited, only the basic problems to solve power Casio np-40 battery technology is difficult to further advance.
