The next generation of laptop battery guess: will replace lithium-ion polymer

December 8th International reported that lithium polymer battery technology has been developed 9 years, and now, it may be to see the dawn of their own.

Sony Electronics president Stan Glasgow said on Wednesday that Notebook makers will “likely” will soon be lithium polymer battery to replace the existing lithium ion batteries.

Lithium polymer batteries use lithium as an active ingredient. Lithium is a volatile material, and existing lithium-ion batteries is different is that a new battery which, lithium component is present in a polymer gel. This gel battery energy density as lithium ion batteries, but the researchers are constantly improving it,

Manufacturers, particularly Sony’s lithium-ion battery energy density (capacity) is very high. When an internal short occurs, it will cause a series of knock-on effect, which burst into flames. Dell, Lenovo, Toshiba, Apple Computer and Sony and other manufacturers over the past two years, has recalled millions of lithium-ion batteries.

Glasgow said: “This is because we will be among the lithium-ion battery energy density increases caused by too great.”

In the past, lithium-polymer battery life not meet the needs of manufacturers and users. Mitsubishi Corporation in 1997 notebook computer in its Pedion which used lithium-polymer batteries, but the effect was not good. This notebook contains a number of new technologies such as ultra-thin design, metal shell, etc., but it cost nearly six thousands of dollars, and there are some technical issues.

Even so, designers have always liked lithium polymer batteries, because of its polymer gel can be squeezed into empty spaces. Lithium-polymer technology has been a lot of improvements. Some manufacturers are using it to call them.

Lithium-ion batteries due to fire danger of explosion, a number of manufacturers are developing non-lithium-ion batteries. For example, Zinc Matrix Power and PowerGenix companies in promoting the so-called zinc-ion batteries. Zinc Matrix has said they will begin selling in 2007, zinc-ion batteries. Glasgow also believes that these batteries will soon appeared on the market.

He said: “I think the next 12 to 18 months, these new batteries will appear on the market.”

Fuel cell is also actively in development.

Haiyin market, the pretext of “Canon” batteries checked

Yesterday, the Guangzhou City Industry and Commerce and technical supervisors and other law enforcement departments in the report, together right, etc. Guangzhou Haeinsa electronics market in several major clean up and rectify the focus on marketing of fake and “Canon” battery products, illegal business. During the operation, uncovered a total fake “Canon,” a large number of battery products, punished some of the illegal sale of counterfeit products business.

It is understood that, recently, some of the illegal use of the consumer businesses, “Canon” brand of trust, shoddy, their own purchases without any quality assurance counterfeit batteries labeled the “Canon” logo and then sold to consumers in order to reap ill-gotten gains.

According to the law enforcement officers, due to the current illegal vendors selling fake products on the market often together, or even tertiary to invite some minion to act as eyes and ears of law enforcement agencies to come to market, once a check, it will immediately notify the market of fake goods stalls will be fake transfer, thereby increasing the difficulty of enforcement of the law enforcement agencies. In view of this situation, law enforcement officers have also taken measures to cope, to ensure the combat effectiveness.

According to professionals, recently, due to machinery damage caused by counterfeit batteries and users of injuries occur. Law enforcement officials to remind the majority of consumers purchase batteries, must not be greedy little cheap, as far as possible to the relevant store to buy the brand licensing.

Solar cell technology breakthrough: 40% conversion efficiency of super -

U.S. Department of Energy (DOE) announced a new solar cell, the conversion rate of more than 40%. The battery is produced by Boeing-Spectrolab, through mirrors and prisms to increase the battery into the sun. DOE said that the price of this battery-three dollars per watt, producing electricity cost of 8-10 cents / per kilowatt-hour.

Traditional solar cells conversion rate is only about 15%, while the new battery to use this concentration relatively low-cost mirrors and prisms to focus sunlight on to the battery on the more expensive gallium arsenide part to improve the conversion efficiency.

Spectrolab’s forecast current technology conditions, the conversion efficiency of solar cells could eventually reach 45%.

Light fuel cell vehicles are expected to enter the market within five years

Automobile manufacturing sector, according to a schedule, starting in 2010, sales of economically viable fuel cell vehicles will enter the market. To this end, Tongji University Automotive Institute has launched this future vehicles, “lightweight” research to try to overcome the fuel cell vehicle power system too much weakness. The news was announced yesterday by the Shanghai Academy of Sciences sponsored by the Center Fellow Sharon learned information.

From the last century, 90 years since the introduction of fuel cell vehicles, which rely on hydrogen, oxygen, chemical reaction-powered cars have been generally optimistic about the industry, is considered the best alternative to internal combustion engine vehicles, one, because it not only saves oil, and will not cause any pollution. But at the moment, our R & D of fuel cell vehicle power system weight of 200 kg weight than ordinary cars as it enters the market a major “stumbling block.” To this end, Tongji University started a series of lightweight vehicle research and development program, the hospital developed “beyond the numbers” series, locked in the target weight of 1351 kilograms. According to Dean Yu Zhuoping introduction, they are for the fuel cell vehicle batteries, body material, structure and other aspects worked out a detailed weight loss program to promote such future automotive market as soon as possible.

Lithium-ion power battery production line

Shanghai, already have produced lithium-ion battery cathode materials capabilities and technologies, to be lithium-ion battery separator production capacity in the city to form after they have met all the conditions for production of lithium-ion batteries and foundation. Project construction content and scale: annual output of 1.8 million lithium-ion battery. Market Analysis: Lithium-ion batteries are widely used in mobile phones, notebook computers, video cameras and other portable electronic products, lithium-ion battery can also serve as hybrid electric vehicle power supply, as well as aerospace, deep-sea areas such as the charging power supply operation. Lithium-ion battery with the traditional nickel-cadmium, nickel hydrogen batteries, compared with a high specific energy, long cycle life, no memory effect, security, pollution-free and fast charge and discharge, etc., it is estimated that China’s current account for lithium-ion battery production for more than one-third of the world’s total. At an alarming rate to gradually replace the nickel-chromium and nickel-metal hydride batteries, and has become a major consumer electronics products, power supplies, from China and the global market perspective, the market potential for lithium-ion batteries is enormous.

Global prices laptop battery shortage

Since August this year, Dell laptop due to the existence of the company had to fire risks Sony laptop batteries recalled Sony batteries have been plagued by the problem, Apple, Lenovo and other major notebook manufacturers also have to recall defective Sony battery. Today, the recall of army recruits have added a.

Last weekend, the Japanese electronics maker Sharp Corp. announced that the company will soon start the recall plan, have been sold to recall 2.8 million Sony laptop batteries.

At the same time, Japan’s Fujitsu is also the official Web site announced that the company will be an additional recall of 51000 Sony laptop batteries. Earlier this month, Fujitsu has launched a worldwide recall 287,000 Sony laptop battery plan. At this point, Fujitsu to recall Sony batteries, the total number of 33.8 million units.

Yesterday, the reporter learned from Sony China, the two companies announced before the operation is Sony’s recall part of the plan. The company late last month announced a plan to recall Sony laptop batteries. Sony China’s press spokesman Kang, said: “Sony plans to recall the statement before, whether or not to recall notebook production company solely by its own decision.”

The batteries are in Japan

“It’s 28000 Sony laptop batteries in Japan, domestic sales do not involve overseas.” That day, Sharp spokesman Hiroshi Takenami said.

Sources said that prior to Apple, like Dell’s recall of Sony batteries, Sharp in this recall defective batteries may also be in use during the short circuit, which led to overheating and even fire.

Previously, Sony had said that when the metal particles and some of the problematic position of the battery contacts, a rare short-circuit phenomenon may occur.

However, Fujitsu does not disclose the flow of additional battery recall problems. The company only said that after the receipt of additional information about Sony, Fuji-rounder has taken an additional recall.

Other products not already covered

Sharp with the latest recall of events, since August this year, a total of 7.7 million Sony laptop batteries recalled by the major notebook companies, while the greatest number or Dell, there are 4.2 million.

As the battery is not only confined to the Sony laptop battery products, the industry’s widely speculated that Sony, the battery recall will be enlarged, involving other electronic products, batteries, such as DVD players, music players and Sony PSP game console products such as batteries .

Sony China’s Healthy yesterday in response to this argument by saying: “At present, the company recalled products are also limited to the laptop battery recall does not extend the scope of the evidence.”

The recall also makes Sony faces a huge crisis of confidence. At present, the company is still assessing a series of financial impact of the battery recall. While the recall may have little effect on Sony’s financial performance, but many well-known customers roll in. They all think that the Sony battery recall culprit.

Cause the battery out of stock prices

The recall is not only a direct impact on Sony, Apple, Dell and other companies, other global battery manufacturers are also subject to a certain extent, lead to rechargeable batteries in short supply, prices and delivery delays and so forth.

Taiwan chin, electronics, Hongliang businesses and resistant to battery 3 battery maker, says that Sony laptop battery recall program led to shortages, this situation will continue until next June. Analysts believe that the battery shortage may reduce the notebook and portable music players and other electronic products in the sales this Christmas shopping season.

Because of shortages in Taiwan, over the past 3 months the battery prices rose about 15%, and there are once again rising trend. In addition, the order of the customer needs to wait for the previous two months time. Sanyo, Sony is second only to the world’s second largest rechargeable battery maker. Sanyo and Samsung came in third place, currently do not have enough capacity to meet market demand.

(International) U.S. solar photovoltaic conversion rate hit a new record

December 6 Xinhua released by the U.S. Department of Energy on the 6th that the United States an organization to produce solar cells created a photoelectric conversion efficiency of 40.7% of the new record.

Such solar cells by the Boeing - Spectroscopy Laboratory of manufacture, its solar panels using different semiconductor materials, the interface of various materials have formed a special thin layer. Such a structure will enable solar panels “inclusive” in a larger spectral range. Compared with ordinary solar cells, the new battery can “seize” the sun for more kinds of wavelength photons, so that photoelectric conversion rate of 40.7%, and the present widespread use of solar photovoltaic conversion rate was only 13% to 22%.

U.S. Department of Energy believes that the outcome of the research and development has taken an important step, as a basis is expected to eventually developed the ideal solar cells. It is estimated that a 1-watt installation cost of this battery is only 3 U.S. dollars, generating cost of 8-10 cents per kWh. This solar cell will be extremely competitive.

U.S. media said the fuel cell vehicles significantly more environmentally friendly, auto show debut

Beijing held a grand Motor Show. In this exhibition, a total of from more than 20 different countries participated in hundreds of new models on display, including several of the latest fuel cell concept car. The concept of environment protection and energy has already begun at this Beijing auto show further demonstrated.

Energy and environmental protection is an international automotive technology is currently the biggest problem. In this context, hydrogen fuel cell technology has become the focus of the major auto giants compete. In addition, as a transitional technology, hybrid, bio-energy powered vehicles have also been displayed on the Beijing auto show. Chevrolet Sequel hydrogen fuel cell vehicles has been described as General Motors of the most cutting-edge technology, but also the world’s most advanced technology. According to president of General Motors said the company will launch 100 units in 2008 car Sequel. Because it can not be considered a true sense of mass production, so this model run and did not give the actual pricing. But once you start a large-scale mass production stage, this fuel cell vehicles in the price will remain a considerable competitive advantage situation.

Wang Chuanfu: 37-year-old riches legend

Was originally a penniless farm children, 26-year-old when they become a senior engineer, associate professor; in just seven years, nickel-cadmium battery production and sales will be the world’s first, second nickel-metal hydride batteries, lithium batteries ranked third, 37-year-old has become well known around the world, “king of mobile phone batteries”, sitting on 338 million U.S. dollars of wealth; in 2003, he spent a lot triumph and the automotive industry, vowing to become the auto magnate … … he is the Chairman of the Board BYD Company Limited Chief Executive Officer Wang Chuanfu. What is the success of the myth of his youth entrepreneurship has become the business Wizards it? Many people think the answer is wisdom, refined and sweat, and he himself believed that “the most crucial thing is to have spirit of adventure.”

Craziness: Battery king-made cars

If we say that it alone in terms of entrepreneurship is the first time for Wang Chuanfu adventure, then the decision to manufacture car is undoubtedly his adventure craziness. January 23, 2003, BYD announced that the price at 2.7 billion acquisition of Xian Qin Chuan Auto Co., Ltd. 77% of the shares. Geely, BYD, after becoming the country’s second privately-owned car manufacturers.

August 2003, in Shaanxi and Guangdong to promote trade and economic cooperation conference, Wang Chuanfu Zaibao surprise move, BYD and Xi’an High-tech Industry Development Zone, Shaanxi Provincial Investment Group signed a joint venture contract BYD electric vehicle production line, the project investment of 2 billion yuan.

Wang Chuanfu idea is that by battery production areas of core technology strengths, build electric vehicles in China and the world’s No. 1 brand, “Battery king” will build cars with their combination of long items. Wang Chuanfu self-confidence comes from BYD in battery production’s success. He wanted to copy such a success, he spotted a huge car for the city of Chang Wang Chuanfu BYD made cars to find a good reason. First of all, three years later, the battery manufacturer BYD will reach its peak, the need to find other industries to expand. Second, relative to state-owned enterprises, the BYD has institutional advantages. Domestic private car market, more than 60% annual growth in the great room will be full of temptations.

“I do a car on the rest of my life.” Wang Chuanfu said.

In January 2004, Shenzhen has 200 BYD-made lithium-ion electric cars into rental operations, became the first electric car demonstration area, truly zero-emission exhaust. This electric vehicles on a single charge after driving 350 km, the cost price in 10 million to 12 million the retail price of 14 million. Have finished the necessary improvements, will fully enter the Beijing market, and in Shanghai, Guangzhou, Xi’an and other cities listed.

In 2006, BYD electric cars to be officially began commercial operations. And in Wang Chuanfu the “plate” also have such a plan ready: BYD Holdings Qinchuan The main purpose of the acquisition of a small car enterprises, to develop electric vehicle batteries, want an electric car as a stake in the domestic manufacturing, and The company has developed electric vehicles with rechargeable batteries. It is reported that BYD Auto R & D departments are Qingli design and planning, 1.3 to 3.0 displacement displacement of Eight series of car development program. BYD Auto to build in the main plant is located in Xi’an Hi-tech Development Zone, combined with the existing car production lines to reform. At the same time, BYD was established in Shanghai, “BYD Auto R & D center.” Soon, BYD Auto will reach an annual output capacity of 300,000 cars, becoming another major car production base in China.

While planning for Wang Chuanfu interlocking looks, but many believe that the charge is far from the car industry, the difficulty of the current technical condition can imagine, Wang Chuanfu the repairer is a crazy dream is no doubt a dangerous move. In this connection, with a background in engineering master’s mind should have a spectrum Wang Chuanfu.

German scientists made a new type of anion-cell materials

November 11, Freiburg, Germany, Institute of Chemistry, University of British Gock crossing after several years of research produced a new type of anion, can be used as durable and high-power battery materials.

Anion is negatively charged atoms or molecules, as a part of the electrolyte in the battery charge transport between electrodes. According to the German “Le Monde” recently reported that crossing a large one made of anionic charge density is very small, and the combination of weak cation, hence the name weakly coordinating anions. Such ion-wrapped with a layer of Teflon external.

Because of this anion attraction is small, and the electrolyte in the weak interaction of other components, thus making a highly conductive electrolyte can result in rapid delivery of high-intensity current of the battery.

In addition to high-power batteries for the manufacture of durable things, this new type of anion can also act as a catalyst to accelerate chemical reactions. It is not only stable, and easy to manufacture, low cost.

Beijing introduced electric bicycle battery recycling system of used methods

According to the China Bicycle Association, the relevant experts, the electric bicycle used by the lead-acid batteries, the main components are lead and sulfuric acid, usually a battery using a period of one year or so. At present, dealing with lead-acid battery technology has matured, but because of the use of electric bicycles TV towers, and how to spread of household batteries are collected for centralized disposal is a pressing need to address the problem.

In response, environmental protection, industry and commerce, public security departments have jointly issued a circular, lead-acid battery for electric bicycle products for registration, the implementation of catalog management, and those who registered in the directory of the battery products can be sold in Beijing.

Learned from the Beijing Municipal Bureau of Commerce and Industry is currently sold in Beijing in the region of electric bicycles and electric bicycles lead-acid battery should go to the registration of business and environmental protection departments, the implementation of content management. Only the vehicle performance in line with national standards, vehicle weight of not more than 40 kg, has a good foot function, and the statutory inspection by the state institutions sampling qualified products can be included in the directory. Industrial and commercial law enforcement agencies will begin the legal market for electric bikes regular sampling and testing does not meet the standards will be out of the market, manufacturing enterprises are responsible for the recall do not meet standards. Also, lead-acid battery electric bicycle manufacturers but also to provide a sound waste battery recycling program, point of sale to provide battery replacement and recycling of waste services, collection of waste batteries to have a business license of waste batteries the unit centrally.

It is reported that the annual environmental protection departments will be assessing the recovery rate of the enterprise for two consecutive years up to standard lead-acid battery products, we are no longer included in the directory, and can no longer be sold in Beijing. Beijing Municipal Environmental Protection Bureau of Solid Waste and Noise Management Branch, Cheng Xia, told reporters that municipal environmental protection bureau in the directory annual assessment of waste lead-acid battery recovery. According to Cheng Xia introduction, the general use of lead-acid battery electric bicycle. Abandoned if it is not the safe disposal of batteries, it is easy to environmental pollution. Electric bicycle ban, to a certain extent will environmental safety risks. The past, some small vendors without permission of the used batteries for recycling, and sell them around does not address the disposition of qualified companies. Can not guarantee that these companies harmless treatment, often leads to secondary pollution.

To industry sources, sales of enterprise products to enter the available directories, manufacturers must undertake to the point of sale of its lead-acid battery used lead-acid battery is responsible for providing replacement and recycling. Manufacturers must be the point of sale agreement, if the electric bicycle

In addition, manufacturers in the government sector for registration, must submit a corporate commitment and undertaking to properly handle the waste batteries. This includes ensuring that the recovery rate of waste lead-acid batteries in 2006 no less than 50% in 2007 no less than 70% in 2008 after no less than 85%.
