10:31 am	What's wrong with Your Batteries ?? Now we all know that there is a time that the laptop battery in your device will have gone through enough charge/discharge cycles that it decides to not play anymore and you need to replace dell Inspiron 6400 battery. There are ways you can tell that your dell Inspiron E1505 battery just won’t last much longer. Such as when the device lasts for only a short time after a full charge, the cordless phone that only lasts 15 minutes into a conversation before sending you scrambling for the rarely used phone in the other room. Like when your laptop dies 30 minutes into a movie right after a good plot twist. We had a call the other day for a camcorder battery, the device had all the earmarks of having a dead battery; it wouldn’t turn on, the charger “seemed” to be charging the battery, and it was an older battery having served faithfully for several years. As I searched for the battery for the camcorder (which the battery apparently is no longer made anymore) I learned something interesting had happened to the camcorder. One thing about electronics that anyone who has dropped their cellphone in the toilet or other water can attest to, is the fact that electronics and water do not usually mix well. This person’s camcorder apparently got hot in the heat of the day and decided to go swimming in the lake. Having served the family so long, the owner could not bear the loss and jumped in to rescue the electronic servant. After letting the camcorder dry out and carefully wiping dell Inspiron 6000 battery down with a towel it was turned on. Realizing that nothing was happening the owner assumed the battery had finally given its last hoorah and needed replacement. However unless you own a device that is either water-resistant or waterproof such as an underwater camera the chances are pretty good that the device committed suicide when laptop battery took that plunge into the briny deep.

10:24 am	Goldman Sachs Approves Panasonic’s Offer For Sanyo After two failed bids to acquire laptop battery financial firm dell Inspiron 1150 battery has finally accepted an offer from dell Inspiron 1300 battery to acquire Goldman’s stake in the company. Goldman will now join Sanyo’s other major shareholders, Daiwa Securities SMBC and Sumitomo Mitsui Banking, in relinquishing control of Sanyo and allowing Panasonic to create an electronics giant. Panasonic announced their intentions to acquire Sanyo last month but had to revise offers made to Goldman in order to complete the deal. Daiwa and Sumitomo initially accepted the offer from Panasonic and are expected to go along with the final deal to be made official by both Panasonic and Sanyo on December 26th. Goldman finally accepted an offer from Panasonic estimated to be 131 yen per share ($1.47) although that figure is still considered to be below Sanyo’s market price. The final offer price for the acquisition is expected to be near 560 billion yen, or $6.36 billion with a tender offer as early as February 2009. Panasonic is interested in acquiring anywhere from 50% to all of Sanyo’s shares. The merger will create a consumer electronics giant that will be able to compete globally with other leading electronics and battery companies in China and South Korea. Panasonic, which manufactures everything from televisions to dell Inspiron B120 battery, is interested in capitalizing on Sanyo’s industry leading “green” technology including laptop battery and rechargeable batteries. The technology and patents owned by Sanyo will allow Panasonic to expand their reach into fields previosuly dominated by Sanyo and perhaps signal a shift in car manufacturing to include lithium-ion batteries and other renewable energy sources.

4:25 pm	The key equipment and technology risks looming shortage of thermal thin-film batteries (b) First Solar is not easy to copy The past two years, the rapid growth of the global thin-film laptop battery industry to drive a lot of fast-growing businesses, the most typical is the First Solar, the company is headquartered in the United States, Arizona, engaged in a cadmium telluride thin-film battery manufacturing manufacturers, the current thin-film battery products in short supply, orders had already been booked until after 2010; its stock in a year and a half rose nearly 10 times, becoming the United States enjoy the highest market valuation of the photovoltaic unit. In domestic enterprises, has been with Suntech polycrystalline silicon photovoltaic Dell Inspiron 9300 battery, Dell Inspiron 9400 battery market has become the world's top three companies in the field of thin-film batteries, the domestic can appear similar or even beyond the First Solar's enterprise? Zhang Shuai said, First Solar gross margins above 50%, which the future development of the industry, released a very positive message. However, First Solar thin-film cadmium telluride mastered the core technology, equipment, mostly of their own design process is also self-developed, so the cost than buying turnkey business is much lower. From the cost breakdown can also be verified that, although First Solar equipment depreciation for 5 years and 7 years than the AMAT shorter, but still higher than the depreciation cost of the unit AMAT amorphous silicon product line for more than 20% lower than the AMAT of the production line laminated lower than 40%. "First Solar thin-film producers around the world set a good benchmark, but it is stunning the target is not easy to stand and the general business of." Zhang Shuai said. Wang Xuefeng stressed thin-film battery business success requires sustainable development potential, has a stable core technology team is a decisive key to the future. First of all, with the crystalline silicon cells are quite different, widely used in manufacturing thin-film Dell Inspiron E1405 battery, Dell Inspiron E1505 battery technologies such as vacuum coating, more like the semiconductor industry, so the skills directly affect the level of product yield and the yield learning curve, indirect impact on the profitability of the enterprise This is from the large LCD factories, IC manufacturers a huge difference in profitability can be seen by; Secondly, the thin-film battery industry is a technical constant innovation and development of the industry, and some process route are not yet ripe, so from a technology need to continue improve the point of view, than the crystalline silicon thin-film battery manufacturer battery manufacturers need a strong R & D and technical team; third, thin-film battery production equipment with high technical barriers, so the supply of thin-film battery production equipment, there is scarcity manufacturers, production capacity is limited technology maturity, technology patents and other issues, thin-film battery industry to release the actual production capacity will be affected by this bottleneck constraints; fourth, thin-film batteries equipment suppliers to provide customers such as "stupid machine" turn-key service, but power companies self-designed process equipment development trends, has a strong technical strength of the manufacturers as a basis for designing more advanced process equipment, in technology and the cost will go beyond reliance on turn-key vendors. Technical Prospects still variable Is generally believed that the declining cost of crystalline silicon cells there is the limit, while the thin-film cells is much greater potential for cost reduction, mainly due to rapid technological advances in thin-film batteries. According to "Photon" predicts the average price of polysilicon components by the end of 2007 will be 3.92 U.S. dollars / W down to 2012 2.08 U.S. dollars / W, thin-film batteries from the current average price of 2.65 U.S. dollars / W down to 1.11 U.S. dollars / W, with the obvious advantages compared to crystalline silicon. And related thin-film battery manufacturers more optimistic forecasts, EPV is estimated that by 2011, the cost of thin-film modules will be much lower than 1 U.S. dollars / W; Oerlikon even estimated that, with the conversion rate and scale, power station in 2011, GW-level the cost of its components will be reduced to 0.7 U.S. dollars / W. However, some analysts say this cautiously. United Securities Research analyst Yang Jun said that the status of crystalline silicon cells is difficult to shake the short term, will continue to occupy a dominant position in a very long time, and investors often commit the error and superstition of new technologies, such as low cost manufacture of polycrystalline silicon Dell Inspiron E1705 battery, Dell Latitude D500 battery, significant increase in conversion efficiency of solar cells, thin-film batteries. "If so, why not go short oil futures?" He asked. Days congenial Gu analyst LI Ya-hui also pointed out that crystalline solar wafers in the current high price case, the thin-film solar cells ushered in a good opportunity for development, an increasingly strong market demand, but if the next crystal silicon solar energy prices had fallen sharply thin-film solar cell products in the market demand may be affected, the market demand may fall.

4:18 pm	The key equipment and technology risks looming shortage of thermal thin-film batteries (a) Recent demand for thin-film laptop battery can be used to describe an extremely hot. In June 2008 the German Photovoltaic Exhibition, 2008, Taiwan's annual production capacity of only 30MW green energy, to be signed orders amounted to 200MW, is the 2009 annual production capacity of six times; Yutong yet the amount of solar energy production, has also made orders for 60MW. Accordingly, following the solar components of heat, hot after the polysilicon thin film photovoltaic cells has become the new investment hot spot areas. In June 2008, Tianwei change security plans to invest 3.2 billion yuan for the amorphous silicon thin-film solar cell projects; LDK Solar announced the construction of the world's most technologically advanced in Nanchang, the largest thin-film solar cell projects; in July 2008, strong Health photovoltaic cells 25MW amorphous silicon thin film solar dell Inspiron 1150 battery,dell Inspiron 1300 battery production line officially put into operation; Jiangxi be able to share announced the formation of joint venture to build production capacity target of 50MW of amorphous silicon thin film photovoltaic cell production line. Prior to this, Suntech, Vosges stake in Rio New energy, variety of shares and other companies also have announced its entry into the field of thin-film batteries. Lack of key equipment and technology, raw materials, restricted In fact, as early as age 70 in the last century, amorphous silicon thin film was developed, but because conversion efficiency is only half of the polysilicon has not been universal. In recent years, favored the growing photovoltaic industry, triggered a crisis in the supply of silicon materials. Silicon raw material prices soaring, making thin-film batteries flaring up again. In 2007, the global thin-film solar cell production reached 400MW, over 181MW significantly in 2006, an increase of 120% market share in 2006 from 8.2% to 12%. However, the securities industry analyst at Societe Generale said Wang Xuefeng, thin-film batteries, after all, at the early stages of development constraints faced by a number of issues, such as technology maturity, the lack of professional and technical personnel, the lack of sophisticated equipment manufacturers, and some still exist in process technology, patent rights, etc. Internal factors from a variety of thin-film battery point of view, the different thin-film batteries dell Inspiron 1420 battery,dell Inspiron 1501 battery each have their own shortcomings, or the low conversion efficiency, or environmental safety issues, and some raw materials, there is scarcity of resources issues that also need to gradually scale industry, after 11 solution. Thin-film battery technology, key equipment and raw materials, primarily from foreign corporate control. As the thin-film battery technology development time is shorter, does not form a common technology and common equipment, the current large-size thin-film battery devices offers turnkey project is mainly the United States, Applied Materials (AMAT), Switzerland, Oerlikon and Japan's ULVAC 3, the former two large-size thin-film batteries occupied the major markets, although there are also other companies to enter the market, but a lower share. Golden State Securities analyst Zhang Shuai said the new energy industry, equipment depreciation is one of the major costs of thin-film batteries, according to the current market quotation, with the capacity of battery production line of thin-film crystalline silicon prices are 6-10 times, and the rate of thin-film battery technology updates fast and the corresponding equipment renewal cycle will be shorter than in crystalline silicon for thin-film battery manufacturers put forward higher requirements. Zhang Shuai stressed that the current thin-film batteries are the main raw materials of international giants monopoly, high prices and supply insecurity, has become the development of the industry's worries. The main thin-film battery dell Inspiron 1520 battery,dell Inspiron 1521 battery materials, including glass (conductive glass and other glass), EVA, target, and gas. ITO thin film batteries require a higher current strength of weak domestic manufacturers, the market mostly by Japan, NSG and the U.S. AFG divided, with the outbreak of the domestic film production, very tight supply situation that may arise. Target current domestic supply being dominated by large international companies, Heraeus, Germany is the world's largest supplier in the domestic market share of over 60%; In addition, there is no domestic production silane, and the main international manufacturers expand production coupled with limited demand for LCD and other high silane partial supply is still tight, prices continue to rise to maintain high level does not exclude the possibility of a number of new entrants into the domestic film industry, companies need to seriously consider.
