HP recalls 203,000 battery unknown number of Chinese market

Notebook computer batteries overheating due to fire, Hewlett-Packard last week said it would take the initiative to recall 203,000 batteries. Involving an unknown number of the Chinese market, but HP has said China will help users for free replacement. This is the Sony 2007, since the scandal broke out a large-scale battery quality, PC manufacturers one of the largest battery recall.

Group, HP China, the relevant responsible person said that the need to recall batteries due to the presence of "internal short circuit may overheat and cause burns," the security risks. Reportedly, these batteries sold in August 2007 to March 2008 between, involving 21 models of notebooks.

Recall of notebook batteries overheating problem events occur frequently, including Hewlett-Packard late last year, including five PC makers recall about 100,000 batteries, the battery problem has become the PC industry can not afford to heart disease, major year 2007 PC makers recall Sony-made batteries only as high as 13 million.

STMicroelectronics to promote ultra-thin lithium battery technology

Chip maker STMicroelectronics (ST) has announced the next generation of rechargeable batteries and the United States signed a commercial agreement FET developers, the application of market adoption of the new FET's "nano energy" ultra-thin lithium battery technology.

Solid-state physics elastic ultra-thin battery technology is one of the main features, it can be made "flexible" the ultra-thin batteries, only 200 microns thick, the thinnest, the battery can also be made of different shapes and sizes.

In addition, such batteries using solid-state electrolyte lithium phosphorus oxygen and nitrogen, this material was originally developed by the Oak Ridge National Laboratory, makes thin-film battery FET output power than the current most advanced button battery 10 times to 20 times.

ST relevant responsible person said, the current advanced a wide range of portable electronic products, have become increasingly demanding on the battery, but the power of performance, life and environmental impacts are behind the development of electronic products, and the gap between the two growing.

Arouse dreams of green biofuels flight

10, Continental Airlines announced here, the first commercial aircraft flight using biofuels recent successful test flight. It opened in 2009, including China, a series of new tests of fuel off the aircraft, once again aroused the people to take the green air travel dreams.

Fuel: Jatropha tree with seaweed extracts and flight

Continental Airlines Beijing office to provide information to reporters, said the plane did not carry passengers on the Boeing 737-800 aircraft for about two hours of successful flight. Continental Airlines Chairman and CEO Luokai Rui said: "Through this test the technical knowledge gained will help to more deeply explore the sustainable development of air transport fuel future."

According to Continental Airlines Chief Representative of China and director of Guoxing Chang introduced to compare the use of biofuels and conventional fuels mixed performance, flight test aircraft No. 1 engine of 100% using the traditional jet fuel, No. 2 engine uses 50% of the extract of Jatropha curcas and algae 50% biofuel with traditional jet fuel. This mixed bio-fuels will greatly reduce carbon emissions. Jatropha curcas and algae in their life cycle can consume a lot of carbon.

Despite the sharp decline in global oil prices in early 2009, but in the long run, to reduce oil dependence, reduce costs and achieve air emission reductions, the new fuel by the way the aircraft is a must. In addition to Continental Airlines, New Zealand, Brazil and other countries are carrying out bio-energy aviation flight experiment.

Bio-energy use, inevitably raises concern for food security. In this regard, Luo Kairui said, and the extraction of fuel from corn and other grains is different from seaweed extract mixed with Jatropha curcas on food crops or biofuels will not adversely affect the water supply can also reduce deforestation.

Do not burn oil aircraft: new technologies need to overcome the revolution

International Air Transport Association recently announced in Beijing, the world's first prototype solar-powered aircraft will conduct the first test flight in early 2009 and is expected to arrive in China within the next two years.

And the mixed fuel of different aircraft, the aircraft does not use solar energy vehicle oil. Bisignani said IATA director, the world's first solar-powered aircraft earlier this year after a first test flight is expected in 2011 to fly around the world including China.

Boeing, one with a proton exchange membrane fuel cell and lithium-ion batteries for small manned plane, successfully conducted its first test flight last year. Driven by a pilot of the aircraft, relying on battery power at 1000 m altitude of 100 kilometers an hour flight for about 20 minutes.

According to reports, China's Trina Solar Company and Air France jointly developed by Lisa new energy powered aircraft is also expected to complete the assembly of the end of 2009. This will be the world's first solar and hydrogen energy to power the new aircraft.

China Dream: energy saving and technological innovation

International aviation community believe that the use of aircraft fuel mix is expected to put into commercial operation next 5 years. Totally ordinary passengers to take the new aircraft burning oil, it may take 20 years or so.

"We hope that the new fuel mix of aircraft operating in the China-US route as soon as possible, the sooner the better." Continental Airlines Chairman and CEO Luorui Kai said.

In recent years, IATA has been working to promote the reduction of carbon in the air and plans. After the United States as air power and the world's second largest consumer market of aircraft, aircraft fuel in China is facing new challenges in research and development.

At present, the total cost of airline fuel costs 36% to 40%, if the new fuel, can effectively reduce aircraft operating costs and reduce greenhouse gas emissions.

IATA's airline industry in the zero-emission process, the investment in new technology in a key position. It is reported that China's current development of biofuels has certain technical advantages, but in non-traditional powered flight is far behind Europe and America.

337 battery patent dispute

Chinese battery companies win in U.S. patent disputes Energizer

Chinese battery company jointly responding to victory over the United States Energizer "337 battery patent dispute case", as Chinese enterprises overseas rights of another example. The results of the victory is important, but the lessons learned for process analysis and continue to "go out" of Chinese companies may be more beneficial.

Unity is strength

Since 2002, China has suffered for 6 years as the United States "337 investigation" the most involved country, by the "337 investigation" of the company is involved in electronics, light industry, chemical, biological, medical device and other industries. But now, responding to China's enterprises, "Section 337" less than ideal circumstances.

During the "337 battery patent dispute case" in the lead by the China Battery Industry Association, the Chinese respondent companies have weathered numerous challenges, and always adhere to the group operations, the industry has not yet have a product exports to the U.S. companies are generous. Chinese respondent enterprises in Fujian Nanping Nanfu Battery Co., Ltd. Administration Department Kangjin Wei recalled: "the meeting in Ningbo, a home out of non-respondent enterprises on the spot 4 million to support the respondent, which is a kind of national spirit."

"Battery Battery Company in favor of '337 patent dispute 'a great inspiration to domestic enterprises." Deputy director of Intellectual Property Academy of Social Sciences Li Shunde, said in an interview, the respondent on the one hand argue to have the courage and the attitude of scientific analysis, to positive response, and dare the respondent, good responding, we can not blindly believe in each other's conclusions can not be negative patient, show a sufficient basis to reasoning; the other hand, the respondent to pay attention to strategy, responding to need money, manpower, resources, legal and other aspects of support, individual companies may weak, but we unite together, through trade associations and other intermediary organizations to win only the possibility of coordination. Particularly in the face of the United States "Section 337" may give the "general exclusion order", responding to the results will affect the development of all enterprises in the Chinese industry, this requires the joint efforts of the entire industry.

Preventive measures

Energizer in the United States on the outcome of litigation lost, but Kang Jinwei, the U.S. companies the importance of intellectual property, but domestic companies should learn. Compared with the Energizer, domestic enterprises lagged behind awareness of intellectual property, ability to use intellectual property is obviously lacking. Kangjin Wei admitted, the defendant after the company realized the importance of patents, patent applications began to study. Nanfu company as the industry's leading enterprise like this, other companies can be seen.

At present, awareness of intellectual property rights of enterprises are generally not strong, resulting in some enterprises, especially exporters exist in varying degrees, the risk of infringement of foreign intellectual property. Wang Jing Zhong of China Battery Industry Association, said the Secretary-General, the enterprise should have a strong awareness of intellectual property, we must understand the situation of the enterprise intellectual property, product development at the same time make sure to do the work of the patent application, so as to really protect their own interests from damage. "337 battery patent dispute," the Chinese firm attorney Stephen Hawking? Stockhausen law firm Zou Guorong are suggestions that Chinese enterprises "going out", be sure to understand the target market, distribution and protection of patents, know ourselves, can prevent the first place.

Enhancing strength is the key

United States International Trade Commission 709 final award decision Energizer patent for its failure to meet U.S. federal patent law described in section 112 of the written request is invalid, mainly due to the uncertainty of China's terms of use patents against other patents. Previously, the 709 was the Energizer patent to the United States, Japan, Singapore and many other battery companies collect royalties for the "killer." According to Zou Guorong said, it is generally believed that the U.S. patent is very strict, patent litigation is usually from the patent novelty and significance of this relatively easy to prove two points to start, very few people with the uncertainty of patent terms. "This is based on our deep understanding of the United States based on patent law, and it is the key to our victory."

"Enhancing strength is the key." Wang Jing Zhong said that mercury-free alkaline manganese battery technology is now very mature, domestic enterprises should be in the new energy batteries such as lithium batteries, etc. to speed up R & D, do the layout and development of intellectual property. It is understood, Changhong Group is currently working on a new generation of digital product development for high-power battery to actively apply for patents. Reporter also learned that quite a few battery companies have to improve their core technology R & D capabilities on the agenda, step by step to innovative projects, the concrete implementation of the work to each quarter, every month.

Silicon Materials and Thin film batteries

Silicon thin-film battery supply crisis led to investment boom

Since the amorphous silicon thin film to be developed, the conversion efficiency of 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 skyrocketing, making thin-film batteries once again surfaced. In 2007, the global thin film solar cell production reached 400MW, 181MW in 2006, compared with a substantial increase of 120% market share of 8.2% from 2006 to 12%.

Corresponding to this, following the thermal solar modules, polycrystalline silicon hot, the thin film photovoltaic cells has become the new investment hot spot areas. In June 2008 the German Photovoltaic Exhibition 2008, Taiwan's annual production capacity of only 30MW of green energy, to be signed orders amounted to 200MW, annual production capacity of six times in 2008; Yutong energy production yet, also made orders for 60MW. Tianwei change plans to invest 3.2 billion yuan for the amorphous silicon thin film solar cell projects; LDK announced in Nanchang building the most technologically advanced and largest thin film solar cell projects; July 2008, Johnson & Johnson 25MW of amorphous silicon photovoltaic film solar cell production line officially put into operation; Gan announced the formation of a joint venture to share and build an annual capacity of 50MW target film amorphous silicon photovoltaic cell production line. Suntech added, Vosges stake in Rio Nisshin energy, variety of shares and other companies have also announced its entry into the field of thin film batteries, thin film batteries attract domestic investment.

South developed enough to each one square meter solar electricity a day

Learned from the Nankai University, Nankai University in the solar energy into electricity has made significant progress, and built the country's largest amorphous silicon thin film solar cell production line, and have the ability to mass production. According to reports, the use of the battery power per hour per square meter, 55 watts, can meet the electricity needs of a family one day.

Also known as photovoltaic solar cells, layman's terms, that is, absorb solar energy, to transform them into electrical devices. It looks like a thin card or glass, the thickness of only 6 mm. Because solar safe, reliable, non-polluting, energy widely available, etc., can be widely used in industry, agriculture, military, civil and other fields, large satellites in the universe, small family radio, charger, solar batteries are ready for takeoff.

Line Chief Engineer, Institute of Optoelectronic Information Technical Science, Nankai University, Thin Film Devices and Technology Institute, said researchers Professor Wang Zongpan, home of the battery, install 1 square meter of a home enough power to use amorphous silicon solar cells per square meter per hour power 55 watts, can basically meet the demand of a family day. Moreover, the amorphous silicon solar cells can generate electricity grid, which will be solar in sunny issued to the excess power transmission grid, to the rainy day or night, the electricity grid will Zaishu previously stored to the user, is fully capable of to ensure continuous use year round.

According to reports, Nankai University, amorphous silicon thin film solar cell production line is expected to double production this year is expected to expand production to 100 megawatts next year scale, equivalent to a medium-sized power plant generating capacity.

New Flexible Solar Cell

Recently, U.S. scientists have found an effective way of making silicon solar cells with sufficient flexibility, which allows it to wrap the object in the thickness of a pencil on top of or attached to the windows of buildings and even cars glass surface. October 5 issue of the "natural materials" magazine reported the results, saying the technology can be easily broken before the transfer to the flexible material on top of silicon, silicon slices for the traditional process provides new possibilities .

Of the study, University of Illinois at Urbana-Champaign, John Rogers, said the new technology will open the door to the promotion of solar buildings, "we can make it thin enough, then 'transfer' in a plastic chip, which to be curled into the system, so similar to the film thickness of the film can be attached to the glass surface of the building. "

It is understood that due to global warming and the impact of high oil prices, relying on photoelectric conversion of solar cells known as one of the most promising green energy. Including Japanese consumer electronics maker Sharp and Q-Cells of Germany, including many companies are making thin-film solar cell research and development related areas. But compared to conventional solar cells, thin film photovoltaic solar cell conversion efficiency lower the industry has been plagued problems.

Rogers said the technology is based on a higher photoelectric conversion efficiency of silicon as a raw material. Monocrystalline silicon wafers in order to overcome the shortcomings of a very brittle friable, they used a special etching method of silicon from a large cut on the silicon than the traditional 10 to 100 times thinner ultra-thin silicon . Different levels according to their thickness can be applied to different areas. When the wafers are cutting down, it will be a device to pick up, and then sealed as the general "transfer" to a new material above the surface. Finally, the re-use these as the electrical system of solar cells together into a whole. Compared with traditional solar panels, highly flexible solar cells that will be easier to transport and install. And Rogers is envisaged that the new materials will be like a blanket was thrown on the car.

"Batteries are not allowed to hide me," the new EU battery regulations

EU European Union in 2006 to promote cell program (Battery Directive), the destruction of the battery, recycling easier, and health programs, has recently been changed out. New battery program, which may include a change to some of the company's dumbfounded, that is: all electronic products must be easy to remove the battery, also known as "battery not allowed to hide me," the new rules.

This provision, it simply is to make users to an open end, a few loose screws to remove the battery can not make the steps easier recovery, but also are more convenient for users, and more willing to waste battery has a good resting place. In short, in addition to iPod / iPhone, the market there are a host of other electronic products in Europe if you want to survive in future, I'm afraid to use your head out!
