Battery

The 9 cell lenovo thinkpad t60 battery. Add a little weight on the standard 6-cell and takes, but if you need to live for approximately four hours of battery life with the Model 15 "screen size. With the T60, without Wi-Fi and the average brightness (third notch 7) drop what I 3 hours and 42 minutes of battery life with light (for writing, or stop). You can expect to find more than three hours with Wi -Fi and finishing a DVD with a 9-cell battery should not be a problem as well, except for The Lord of the Rings.

The screen size T60 14 "is much better compared with the period of battery life per cell because a smaller screen just drains less battery. I think the 6-cell battery for T60 14 "you get what the 9 - to 15 battery" - again, just an uneducated guess.

Windows Media Center as a set-top box

Asus and Acer have the Intel Developer Foum in San Francisco set-top boxes with Windows Media Center presented at. They are based on Intel's TV chip atom 4100 CE and have a built-in TV tuner. The boxes in 2011 for about $ 300 to have his first semester.

The operating system is Windows Embedded Standard 7 are used. It is a special version of Windows 7, in which individual components can be omitted. The set-top boxes, for example, show only the Media Center interface. Switching to the Desktop is not possible.

The demo during the keynote, however, revealed weaknesses: the HD movie was not playing very smoothly. Also to send animations of the surface were missing. Whether Microsoft to market can completely eliminate the problems, still has to show first. to consider is that the atomic CE 4100 with such a resource hungry OS should not be heavily used. Other Smart TV solutions, such as the IDF presented to amino based on Intel's Linux-variant Meego or Google TV, ran smoothly and with animation.

OEMs can customize the interface of Windows Media Center.

7800 United States Government introduced billion economic stimulus package, about 2.4 billion U.S. dollars to finance companies to develop advanced energy storage technology. The U.S. carmaker Ford is responsible for energy storage strategy and research services senior manager Ted Miller, a recent analysis pointed out that the current U.S. government investment in the development of this advanced technology has been advancing over the 2003 when the fuel cell R & D into the United States lithium batteries and other energy storage technology development program will provide 11 billion chemical company 130 billion market opportunity.

The market has formed the basis of

Miller pointed out that climate change, greenhouse gases and air quality, the degree of concern by the whole society is increasing. Currently, the development of market-based lithium battery also exists. Hybrid vehicles currently account for 3% of the U.S. car market share of 4%, almost all of the current assembly of this type of car is still a nickel-metal hydride batteries.

However, Miller said the end of the year, Daimler will launch a Mercedes (Mercedes) S series hybrid vehicles, this series of cars will be equipped with lithium batteries. GM and Ford will also be launched in 2010 lithium battery hybrid vehicles. One after another vehicle manufacturers to introduce more hybrid cars lithium battery applications. By 2015, demand for U.S. automobile manufacturing lithium battery market share will reach 11 billion to 130 billion U.S. dollars.

According to Miller, said, in addition to automobile industry, the demand for lithium batteries and a large power generation industry. The current U.S. government is encouraging power companies to use more renewable resources like wind and solar energy to generate electricity, and solar energy, wind power generation system to be used in lithium battery energy storage devices.

Tremendous business opportunities battery components

Nanorods grown on the aluminum foil can produce solar cells

Nanorods grown on the aluminum foil can produce solar cells

U.S. researchers have developed a new type of solar cell technology, such solar cells can be grown on the aluminum foil to make vertical nanorods, the whole battery packaged in a transparent gel after the polymer can produce flexible solar cells, cost less than conventional silicon solar cells.

Led the research, the University of California professor of electrical engineering and computer science, said Ali Jewitt, and compared to traditional silicon and thin film batteries, nano-column technology allows researchers to use more low-cost and low quality materials. More importantly, the technology is more suitable for the fabrication of thin aluminum foil solar panels can be curved, thereby reducing manufacturing costs. If successful, the cost of production of monocrystalline silicon solar panels will be as low as 1 / 10.

This solar cell is 500 nm by a high single embedded CdS films made of cadmium telluride, and these two materials are often used in thin film solar cell semiconductor. Jewitt and his colleagues in the "natural materials" published reports that such cells will convert light energy into electrical energy efficiency of up to 6%. Previously, scientists have used this column design, but the method is more expensive, and the photoelectric conversion efficiency of less than 2%.

In conventional solar cells, silicon absorbs light and produce free electrons, these electrons must be trapped in defects or impurities in the material before the arrival circuit. This requires the use of very pure, expensive to manufacture highly efficient crystalline silicon photovoltaic devices.

Nanorods assumed the role of silicon, nano-columns around the absorption of light and produce electronic materials, nano-columns will be transported to the circuit. This design to improve efficiency in two ways: tightly encapsulated nano-columns between columns capture the light, the surrounding material to help absorb more light; e to a very short distance across the nano-column, so there is not much chance of trapped defects in the material. This means you can use low-quality low-cost materials.

Some scientists using different nano-structures to the production of such solar cells. For example, the Harvard University chemistry professor Charles in the Boer developed a silicon-containing different core and concentric layers of silicon nanowires; University of California, Berkeley, Yang Peidong were developed with a zinc oxide nanowire dye sensitized solar cells . These nanowires photoelectric conversion efficiency of solar cells has reached 4%.

Jewitt and his colleagues made use of nano-column cell for the first time by the oxidation of aluminum foil, creating a cyclical distribution of the 200 nm wide holes, these holes as a template for the growth of CdS crystals upright. Then, cadmium telluride, and the top electrode decorated with copper and gold films. They are connected by a glass plate and battery, or to the polymer solution into the top of its bent.

Georgia Institute of Technology professor of materials science and engineering Zhong-Lin Wang commented that the nano-materials, engineering design and manufacturing flexible solar cells flexible and efficient technology integration with a variety of soft substrate, this is an exciting progress. U.S. National Renewable Energy Laboratory is responsible for solar cell research, said physical chemist, this battery to and from silicon, cadmium telluride and other materials made of flexible thin film solar cells to compete, its selling point may not be its flexibility, but the cost advantage.

Currently, researchers are exploring the use of the material can improve the conversion efficiency. For example, the top of the copper - gold layer is only 50% of the transparency, if you can have all of the light through, and its efficiency can be doubled. Therefore, the researchers are planning to use such as indium oxide transparent conductive material. In addition, the use of other semiconductor materials as nano-column and the surrounding material is also considered among the researchers, this production process can be suitable for a wider range of semiconductor materials, other material combinations may also improve efficiency, a more important point is cadmium toxicity problems can be avoided.

Battery Industry: internal and external need charging

Battery Industry: internal and external need charging

Accelerate technological upgrading and product upgrades, is held in Beijing before the Ninth China International Battery Fair's most powerful voice. Experts said that China still need to improve product quality, some batteries, the battery needed upgrading industrial technology, electric vehicle batteries, zinc-manganese batteries urgent adjustment of product structure.

Experts also said that China's battery are highly dependent on international markets, especially in solar cells, more than 95% of exports, 90% of the raw materials imported, this "two out" of the market risk is too high, also caused Industry profit-shifting. Relatively backward industrial base of raw materials, key materials still rely on imports, China's high energy consumption, high pollution, low return for economic benefits. Such as solar cell manufacturers, the average profit margin is only about 8%, if the net export tax rebates, enterprise basic unprofitable.

Battery Industry is a comprehensive advantages of the traditional industries, but with new materials, new techniques, new technology, the battery industry is increasingly becoming a new high-tech industries. According to reports, in recent years, China's battery industry showed the following characteristics: production increased steadily, rapid export growth, technological progress accelerated, more reasonable product structure, diversified enterprises, large-scale development, and equipment levels gradually increased, overall strength significantly enhanced. Battery industry has led to the development of China's electronic appliances, metals, chemicals, mining, machinery and other related industries in the national economy played an important role.

The survey showed that nearly 5 years, average growth rate of China's battery sales of over 20% per year, output growth rate of 10%, far exceeding the global average. In the past, the tradition of batteries for low-end products; now mercury-free alkaline manganese battery, a lithium battery, maintenance free valve regulated lead-acid batteries, solar cells Dengjun rapid development. As the world's industrial restructuring in recent years, China has gradually developed into the world battery production, processing and trade center, is the world's largest battery producer.

However, the impact of the international financial crisis, since the second half of 2008, China's battery industry growth rate of exports has continued to decline, battery sales increase in accounts receivable, economic decline. With mobile phones, cars, electric bicycles, and other battery related products production and sales of contraction, the battery output growth rate to fall. Some staff members to participate in the exhibition reflect the enterprise, companies are now facing difficulties mainly due to cost increases battery market is less competitive, corporate profits dropped significantly.

According to the China Light Industry Information Center, the persons concerned, in the first quarter, China's battery industry as a whole run showed the following characteristics: Although the rebound in output, total output value of large-scale battery manufacturers 9.87% over last year, but the international market slump in the first quarter Battery exports fell last year compared to 31.86% over the same period. Affected by the toy exports, a quarter of button alkaline manganese batteries exports continued to decline, cylindrical alkaline battery exports dropped slightly, other alkaline manganese batteries to accelerate export decline. At the same time, business costs rise, profits fall. 1 to 2 months of this year, the battery industry over the scale of total corporate profits fell 68.78%, the battery industry, above-scale enterprises of up to 31.19% loss, the loss amounted to 785 million yuan over last year, up 215.78 percent loss. Loss and further expand the industry, business difficulties. Effect of export tax rebate policy adjustment in China is not yet clear, but the foreign green barriers on China's battery industry continues. According to the European Union, "Official Gazette" batteries and accumulators directive issued for the battery lead, cadmium, and mercury targets made more stringent requirements, and the recovery of the exorbitant costs involved. REACH regulations and directives to improve the battery RoSH registration fees and testing fees, substantially increased the cost of battery production and export sales costs, some enterprises have to because of economic reasons and technical reasons to give up the overseas market.

At present, China's battery industry is facing the full industrial upgrading. Wang Jing Zhong of China Battery Industry Association, said the Secretary-General, recently passed the "light industry restructuring and revitalization plan" will help the battery industry restructuring and industrial upgrading. The battery industry to take this opportunity to fight in the technology and equipment to make significant progress, and form a group with strong international competitiveness of enterprises, so that further domestic product and market development, significantly raise the added value of export products, market more diversified. While promoting electric vehicles, power tools battery with a new industrial scale, making China the world's largest producer of rechargeable batteries, solar cells Baochi world leader in the production and accelerate development, and gradually ease the market shortage, increased battery export variety, improve product quality and added value. "Enhancing strength is the key." Wang Jing Zhong said.

According to reports, the next few years, China's battery industry will accelerate the technological upgrading and product upgrades, anti-risk ability to effectively improve industry and international competitiveness, improve the capacity of independent innovation and brand building, innovation in the industry to establish a sound support system, and further implementation of the technology and equipment domestic, market diversification and accelerate the world's manufacturing power by the battery industry to manufacture the world's power forward. Physics, Chinese Academy of Sciences, said the experts, the establishment of National Research Center for the battery industry, industry consolidation to improve capacity for independent innovation, promote technological progress, we should focus on breakthroughs in battery electric vehicles, car key battery materials, key technologies and research and industrialization. China's huge market for electric bicycles to lithium-ion battery industry has brought opportunity. "The battery is the most critical components of electric vehicles is the result of pooling multi-disciplinary research, enterprises need the government to focus on the choice of quality support." At the show, many companies made such a call.
