Mobile phone battery appeared Yongcheng are doing is a "three noes" product quality concern

A finished battery contacts are not posted, a few rubber, an adhesive tape, after a simple process for any cell phone has become a model of "universal" battery. Recently, the reporter in Nanning city, many temporary stalls found that many stall holders with the word "cell phone battery is doing," the ad through the modified cell shape to meet the needs of different buyers, adding that now is comparable to the brand do the battery cell. In this regard, autonomous regions and product quality supervision, inspection staff to remind consumers, on the market "is doing mobile phone battery" does not meet national standards, quality and safety concern, should be careful to buy.

Battery comes with contact

Minutes can be made

June 20 8:00 pm, at the Seven Stars Road, Nanning City, a temporary stalls, stall the name of "professional mobile phone batteries are made," the ad, is to be a female customer on-site "production" cell phone batteries, lead many people to onlookers.

Reporters saw a pile of marked stall in the "boom up" yellow cells in the non-stop selection, and customer phones up and down than the original battery, and finally selected a shape generally in line with the original battery of the battery. The battery is showing a length of 5 cm long cable, cable terminal with three contacts. Stall will be trimmed rubber glued to the battery a good side, with mobile handset battery compartment fully fit, then align the slots of the metal contact points, fixed in the battery paste and finally coated with bright gold gold tape.

Less than 10 minutes throughout the production process, customers will stall the production of batteries into the phone, turned on phone can be used. Reporters are doing that to a battery, according to Reporters stall immediately to provide mobile phone battery shape, come up with an about 4 cm and a width of 3 cm cell, marked above with the battery capacity of 1000 mA.

Correspondent: Now do the battery and the battery is generally the difference?

Stall: now do the battery more durable, longer battery life than the brand.

Reporter: this capacity 1000 mAh battery available how long?

Stall: a week, brand batteries can only use two three days.

Reporter: Is there a security risk?

Stall: I do more than six months, many people are using this battery, do not have problems.

Reporter: Why did not indicate the manufacturer and lot number?

Stall: getting goods back is like that.

Reporter: Where to purchase?

Stall: Shenzhen. Guangxi is currently no such material available to the wholesale conversion of the battery.

After a few minutes, cell phone battery production is completed, the reporter received 25 dollars stall.

Use the time serious "shrink"

For "cottage phone" born

Does it really make mobile phone batteries are said stall so durable? June 22 afternoon, the reporter will now make mobile phone battery charger with the universal "fully charged" into the phone, the battery shows full grid, began to work properly. However, 24 early in the morning, the phone automatically shut down, the battery charge is depleted.

Ms. Leung has a large public square near the Sha Tin to spend 35 yuan to buy the temporary booths called "Variety King" is doing mobile phone batteries. "Purchase the one that 'do the batteries are' relatively new; stall that is second to do a special battery for the battery, use time more durable." She sighed, "to use after the discovery, at most, can sustain two or three power days, and sometimes the collision cell phone is a little bit, then there is bad shutdown automatically. "

Reporters interviewed found that, in addition to some of the street of small stalls outside the city, many large electronics mall has such a "cell phone battery is to do" phenomenon. In Nanning Ego Digital Technology Plaza, second floor, a mobile phone accessories counter staff said that around March of this year, mobile phone batteries are made only into the market. As the "cottage phone" quick update, mobile phone batteries of different models, the customer is difficult to get the battery and phone support, and are doing to meet almost all models of mobile phone battery mobile phone needs.

He said that mobile phone batteries are made mainly from Guangdong purchase, the battery shape, size, thickness varies, according to the specific needs of customers on-site production, the price of 30 yuan to 60 yuan per month. Reporters asked whether the quality of this battery is guaranteed, he said, the quality is not as good as the brand to do battery mobile phone battery.

Belong to the "three noes" products

Quality concern

June 24 afternoon, the reporter will be sent to cell phone batteries are made autonomous product quality supervision, inspection and electrical rooms, Lin Fan, deputy director of the preliminary examination of the battery and found that there are many problems in the battery.

He first outer tape the battery apart, and then told reporters that the so-called cell phone batteries are made, in fact, on the basis of the finished battery, add some filler, modified appearance, with mobile handset supporting; cable and contact the design approach, but modified to meet the needs. Thus, the battery and the phone junction tightness inevitable defects, the contact area prone to problems.

Secondly, according to the size of the battery to determine the volume, although printed on the packaging, "1000 mA" battery capacity, but the actual capacity is only 600 mA should be about, of course, the use of time, "shrink."

Lin Fan introduced, mainly by batteries cell phone batteries, circuit protection and housing three parts. Batteries are energy storage devices, have high quality requirements, once the production quality is not up to the overcharge or over discharge of the case, it is prone to short-circuit the positive and negative, leading to high temperature and pressure, caught fire and exploded. The composition should include regular batteries effective protection circuit to prevent thermal shock, caused by heavy impact and so the risk.

He said that based on our current "cell phone use lithium-ion battery general norms," the provisions of the domestic market, sales of mobile phone batteries to go through rigorous testing, standard cell surface should be marked name, size, origin, type, performance standards, notes and sheet and other information. In addition, regular cell phone battery should also be marked "cell phone battery production license number." This is now appearing on the market do not phone battery production date, batch number and manufacturer, clearly belongs to the "three noes" products, quality and safety concern, consumers should be careful to buy.

Zhenhua Li-ion battery technology into the partner is Kinwa old acquaintances?

A stock market is the recent lithium battery fire, detached shares are to rise steadily. Now add a new lithium battery unit in turn a member of Concord Technology May 27 announcement that will come up with nearly 20 million yuan investment in lithium-ion battery.

Notice a, Zhenhua Technology heavy volume day limit. However, the main industry Zhenhua Technology supporting military electronic components and more, why this time in conjunction with "fashionable" is not involved in general into a new area? This time investment partners, moved the company's natural Li Shujun, is the story behind?

"Mystery man" airborne lithium battery project

May 27, Zhenhua Technology announced that the company will set up a joint venture with Li Shujun joint venture company engaged in the lithium-ion battery research and development, production and sales, operating range of lithium-ion batteries and super capacitors, 20 million yuan in registered capital, Concord Technology invested 19.8 million yuan, Li Shujun contribute 20 million.

Notice is published, the date of Concord Technology opened directly to the limit price, then limit-despite being open, but still limit the final closing. Day, Zhenhua Technology Volume 2729.84 million shares, almost to the recent average daily trading volume of three times; turnover reached 323 million yuan, 7.62% changing hands all day. The Shenzhen Stock Exchange after-hours data, stock trading day of the first five seats are business department, there is no body figure.

Curiously, Concord Technology as a listing of state-owned enterprises in Guizhou Province, the main products are mostly supporting military electronic components, why would intervene in the field of lithium batteries? And moved the company's Li Shujun, what is man?

Zhenhua Technology announced the introduction of Li Shujun is very simple, "2005, graduated from the Institute of High Energy Physics, Chinese Academy of Sciences, Ph.D. in physics," "is the early development of lithium-ion battery technology, one of the officers, who in Shenzhen, Beijing, number of lithium enterprises. " Dr. Lee now has what technical achievements, Zhenhua Technology announcement did not mention.

From the announcement of view, the investment in Concord Technology is responsible for "spreading the money," Dr. Li Shujun play the role of technology provider. The joint venture will set up lithium-ion battery factory, Zhenhua Technology will be self-funding solution to the problem.

Contacted on the above issue yesterday Zhenhua Technology, but the company secretaries, security transactions on behalf of phone no one answered. Concord Technology Office, told reporters outside the securities on behalf of the current study, secretaries something out; and he himself did not know the circumstances surrounding the matters of the investment company.

Or Kinwa [7.26 0.55%] dealt with?

But the investigation found that the Dr. Li Shujun, should not the first time in A-share investors sight; Barring unforeseen circumstances, he should be in the last year, with another listed company Kinwa (600,110, closing price 7.22 yuan) did transactions.

June 11, 2009, published in Kinwa asset acquisition announcement, the price of the company will be 38 million yuan, from the hands of the transferee Beijing hit two natural sub-battery R & D Co., Ltd. (hereinafter referred to as creating sub-company) 100% equity. The transfer of shares of one of two natural persons, that is, Li Shujun.

Kinwa copies of notice of the introduction of Li Shujun, "the man, August 1, 1970 Health, Doctor," the transaction was to create sub-general manager; and create sub-company was founded in August 2005, the time point and Zhenhua Technology bulletin describes as "the 2005 graduate" match. This company's main lithium-ion cell materials, this is also referred to a Beijing Zhenhua Li-ion battery technology company in line with work experience.

Yesterday's "Daily News" on this confirmation to the above three companies, were unsuccessful. Until 6 pm the same day, Deputy General Manager Tel Concord Technology is still unanswered.

Temporarily can not see the real impact on the company

Although the secondary market for the company to the investment funds on impulse, but from Concord Technology announcement of view, although the company optimistic about the lithium battery industry, but to set their own goals, but slower than the industry peers.

Concord Technology said the company plans to use 2 to 3 years, in the "electric bicycles, light electric vehicles and power tools on the market to achieve substantial breakthroughs", "form a stable business and a full-scale battery industry team." ; and only then consider the next phase of industrial expansion, in the process to follow up "static storage batteries, electric vehicle battery industry opportunities."

Insiders said that, if not their own unique technology, a small lithium battery business is currently difficult to say a big room for growth. Not long ago, before going to Kinwa research had Dongxing Securities analyst Lin Yang told reporters, recalled that when Kinwa additional fund-raising management's focus on investment in the copper project, in addition to wire and cable business and the oil is assets, battery materials business did not mention to him too much.

Kinwa 2009 annual report, then create sub-companies from the date of acquisition until the end of the year net profit of 602,200 yuan, accounting for 3.18% of net profit of listed companies.

Automotive Li-ion battery is developed into a global market will surge of hot

As environment-friendly vehicles are sought after worldwide, hybrid and electric cars popular, the next few years, automotive battery market will expand rapidly. "By 2014, the market will rapidly expand the size to 2.25 trillion yen (24.8 billion U.S. dollars), is about 215 times in 2008." This is a professional market research agency in Japan Economic Research Institute has recently come to Fuji statistics.

Emissions and oil resources in response to the dual pressures of increasingly scarce in most countries the development of new energy vehicles will be viewed as the revitalization of its automotive industry and the most important ways of energy saving, and reduction in the most stressful and the United States for promoting standard-bearer of new energy vehicle development. Recently, China and the United States issued the "Joint Statement", said the two sides will launch in the U.S. electric car initiative, the two countries in the next few years, several million electric cars in use.

In China, released last March, "the automobile industry restructuring and revitalization plan" in the development of new energy vehicles has also developed a general goal - the next three years, China will form a 500,000-in hybrid electric charge and the common type of hybrid new energy automobile production capacity. By 2012, the new production car will have 10% energy saving and new energy vehicles, new energy vehicles are expected to reach 500 billion yuan output value.

Faced with such an attractive market cake, domestic car prices, spare parts and other upstream companies have exposure to which, in order to stay ahead. Compared with traditional vehicles, new energy technology gap with foreign cars do not, there is the possibility of overtaking corners, more contribute to the relevant enterprises to increase investment in new energy vehicles optimism. Among them, the car battery - lithium-ion battery is a major research and development related to the preferred target.

It is understood that the current hybrid cars use nickel-metal hydride battery technology, nickel-metal hydride batteries, but some of the 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., by various car manufacturers and battery manufacturers unanimously approved, is currently the focus of national research and development of lithium-ion batteries.

According to the different cathode materials, lithium batteries are lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate ternary materials, and four. Lithium iron phosphate which is the best vehicle to use lithium cathode material. At present, China's car prices electric car models introduced, the power batteries are lithium batteries, Chery, BYD are using lithium iron phosphate.

Although China ranks third in the world production of lithium batteries, but in products, technology level with Japan, the United States there is a certain gap between the vehicle's lithium battery industry has not really started. Xinhua said the letter, and other related research institutions, China's relatively backward power battery production equipment, many companies will focus on the material, ignoring the improvement of manufacturing equipment. At present, China mainly depend on production of batteries and equipment imports expensive, which our car is very unfavorable development of battery, battery in mass production, it should be advanced automation equipment research first. In addition, most of the enterprises of independent power battery research and development, its limited funds, can only solve the basic problem of battery technology is difficult to further advance. Lack of adequate communication between enterprises, want to know the circumstances of other people do not want to talk about their own experiences, there is widespread duplication of low-level phenomena.

Breakthrough in battery technology is difficult obstacle to the development of smart phones

Competition in the smart phone market is increasingly fierce. As previously reported we have a growing number of smart phone operating system in the efforts to expand its market share, while the manufacturers are also working to improve their market share in smart phones. More and more smart phones available, they are more powerful, more and more high configuration, all display the smart phone market is growing rapidly.

However, the development of smart phones is not a smooth sailing. Despite the rapid development of technology, more and more new technology into the mobile space has been greatly improved user experience, but there are still some bottlenecks restricting the development of mobile phone technology. Battery technology is one of the most important aspects.

Compared to ordinary cell phones, smart phones tend to have higher than normal cell phone hardware configuration, but with more features smart phones have a greater frequency of use. This means that the smart phone's power consumption is correspondingly greater. With the large size of the touch screen into the mainstream, more and more Internet-based applications, smart phone also continues to increase the power consumption trends.

Inconsistent with this development, the mobile phone's battery technology has not made any major breakthrough. The current battery capacity and smart phones a few years ago, to enhance the range is limited, its very difficult life satisfaction of users. As far as I know, a lot of smart phone users are required to charge the battery every day.

Nokia Research Center Henry Tirri said in a recent interview, go through a few years, breakthroughs in related technologies, the smart phone's battery life is possible to achieve "good" level. Henry Tirri that the smart phone battery "good" level is a charge to use about a week, but now many high-end large-screen smartphone was less than eight hours of continuous use.

Short term cell phone battery technology, there is no breakthrough

Defects in battery technology for operators and manufacturers have an effect. Users may hesitate whether to buy a standby time is very short, smart phone, but it also limits the use of smart phone users to make more Internet applications.

Henry Tirri said that as the phone's basic function is to voice and information, so on the phone before the power management of the study was to optimize for both. But in the past two years, with the rapid development of mobile phone technology, there has been a faster processor and more power bigger and brighter screen, and with the "cloud" concept generation, a large number of applications require connected to the Internet server, which also takes a lot of power, however, did not keep up with the battery of this trend.

And taking into account the limited volume of safety factors, the current lithium batteries used in mobile phones is difficult to have much to enhance the capacity, mobile phone manufacturers and battery manufacturers are working on new battery technologies, including the use of solar energy, kinetic energy and so on. However, at present these technologies have no real breakthrough is not yet widely used. ABI Research analyst Michael Morgan said the smart phone battery to get involved in a lot of breakthroughs in technology, but these technologies are related, each technology must wait for other related technology.

Therefore, in the enjoyment of smart phones faster, more feature-rich at the same time, within a period of time, smart phone users still have to endure the pains of the battery can not be sustained. And if this situation would not improve as quickly as possible, perhaps even the development of the smart phone industry a huge impact.
