  News about developed a new type of power battery

  Beijing developed a new type of power battery

  Yesterday, the Beijing Municipal Science and Technology plans to major projects, “Li-ion battery cathode material of lithium manganese oxide of the industrialization of technological development,” the smooth passage of the city of Science and Technology Commission acceptance. Experts said that the city’s scientific research institutions world-wide technical problems to overcome in one fell swoop, in the new type of lithium batteries to achieve a major breakthrough in the development, in order to speed up the development of Beijing to ease the atmosphere of tension and energy issues in urgent need of environmental degradation of the electric vehicle battery to provide the technical support.

  It is reported that the project is the city of Science and Technology Commission on the project in October 2002 and three million yuan in support of UNITA by CITIC Technology Co., Ltd. Solid-Lee power to implement major projects. More than two years, the project unit in addition to breakthroughs in the world to assume a key technical challenges, developed a new type of lithium-ion batteries key materials required for the synthesis of lithium manganese oxide of new technology, also developed a new large-capacity lithium-ion battery power and electric buses in the Olympic Games Test vehicle operation to complete the car, continuing to run more than 10,000 miles kilometers battery in good working order.

  The city has developed a new type of lithium battery — Lithium Manganese battery, is recognized as the most practical electric vehicle battery power. It is, at present, many domestic users, as well as South Korea, France, the United States a number of companies have begun to trial the products of the project.
  “Lithium Manganese” yesterday battery power through the acceptance of 0.68 degrees per kilometer

  Electric buses on the road is expected to

  Zhi-Bin Hu said Beijing photographic look like powder with the same “black magic” of lithium manganese oxide made large-capacity battery, mounted on a modified “big public”, the breath will be able to run 220 kilometers, while the per kilometer only 0.68 degrees consumption … … Yesterday morning at the Beijing Science and Technology Commission, “lithium ion battery lithium manganese oxide cathode materials for the industrialization of technological development” project acceptance at the meeting, vice mayor of Beijing Fan Boyuan said the first batch of 30 electric city bus, this month is expected to be issued by National Development and Reform Commission and the Ministry of Public Security license. Next year, Beijing is expected to have 200 electric buses put into use.

     Magic “black” security money

  Looked at the hands of a staff want to “black” Lithium manganese, it is difficult to imagine it with the volume of production of lithium manganese battery acid than the traditional three times the capacity of lead-acid batteries. “Although mobile phones, digital products, the use of cobalt and manganese lithium battery Lithium battery performance almost, but better than manganese lithium batteries several times the price.” Commitment to the issue of UNITA solid profit technology research and new materials Anping, vice president of hospital told reporters that with this kind of “black magic” in addition to the production of large capacity battery and low-loss, low prices, but also very safe.

  The need for transformation of electric buses 500,000 yuan

  “Like the appearance of the same standard set by the volume, but left one less car exhaust pipe.” Yesterday, the reporters in Lee solid UNITA Institute of new materials technology has seen a transformation of the electric bus. According to the driver, the bus driver this system has been completely replaced by the motor was originally used to store baggage car “belly” full of batteries. “Although it is more than you, but only 4-5 hours can be filled, and if in accordance with the rated load, full time electricity can travel around 220 kilometers.” It is understood that the car has a top speed of 120 km / h, 0-60 km / h acceleration in less than 26 seconds. A total of 108 of its battery power with the needs of 77 degrees, less wear and tear only 0.68 per kilometer driven degrees. “Battery life for each group of about 200,000 kilometers, so even if the transformation of the cost of electric vehicles with 500,000 yuan, almost the same miles and running cost of the fuel car fairly.”

  Electrical products can not enter the public short-term family

  Apart from the electrical bus, the AU’s solid profit in the Technology Research Institute of new materials have also seen the electric motorcycle, electric bike or electric van. “However, apart from public transport to a unified solution by the Government, the development of electric vehicles to the private sector would still take some time.” Ping, vice president, said battery electric bicycle can be demolished, but the larger motorcycle, car battery car you need to charge a fixed supporting infrastructure, “this context the need for government funding and venue support, on the one hand, also need to increase the environmental awareness of the public.”

  Electric vehicles do not directly use the fuel, including pure battery electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, three broad categories. Study of electric vehicles in Beijing has been included in dozens of major technology projects Olympics. Currently, Beijing has developed electric luxury tourist buses, electric low-floor buses, quasi-electric low-floor buses, such as pure electric bus electric bus 4. “By 2008 we have strived to 1000 run electric buses on the road in Beijing.”

  Need a cell phone battery

  Need a unified standard cell phone battery

  Mobile phone has become the social necessities of ordinary people with laptop battery. It is precisely because of too general so that the mobile phone associated with a major anomaly was but turn a blind eye: the use of cell phones there is a huge waste of it.

  And pollution - hp battery!

  Each person using the phone there will be the same experience: mobile phone battery and charger are not common, for a cell phone, it means that a set of discarded batteries and chargers, even the same brand between different models of mobile phones is also so. According to data released by Ministry of Information Industry, the door, as at the end of October 2004, China’s mobile phone users has reached the 320 million people. Fashion phones are consumer products, upgrading the speed of a swift pace. According to each user on average every 3 years to replace the conservative frequency of a cell phone, and each is equipped with mobile phones are generally two batteries and a charger, this calculation, every year there are 200 million cell phone batteries and 100 million mobile phone charger into a litter, and this number also as China’s mobile phone market growing at an astonishing speed and a corresponding rise. Not really do not know, one count surprised!

  The use of modern daily life of the battery can be described as an over-abundance of small electrical appliances, from radios to electronic form, everyone is able to set out a long list. If each of the appliances with cell phones, batteries and chargers for a fixed mix of “monogamy”, we might well have lived in the garbage heap of batteries. Fortunately, we are smart, uniform criteria for battery models, so there will be a 3, 5, 7, and other common electrical appliances in different grade batteries, so we in our daily lives, we just needed to clarify the electrical battery models feel at ease to use, do not have to find a store 372772-001 battery, pb994a battery, hp nc6110 battery brand of electrical batteries and filled with chaos around, there is no need for a throw on a set of electrical batteries and charger (if so equipped). But I do not understand: This product models of a unified standard, both for the convenience of consumers, but also to save resources and reduce environmental pollution, but also from a technical point of view there is no obstacle, why the phone will not work in front of the case?

  Thought to want to go, only to find two reasons: One is to include mobile phone manufacturers, including the public’s awareness of environmental protection is generally weak in many mobile phone manufacturers a strategic consideration, not only to save resources and protect the environment considerations, and we also used the public play a “silent majority” of any kind as long as there is no direct damage to the vital interests of their own acts or the things they share in the habit of silence, even if it has a social and public interests significant harm; the other can only be “good business sense” — the law of a cell phone with battery, charger between the “monogamy” of the mandatory tie-ins, for the cell phone is great source of profits. Just imagine, a charger million, a piece of mobile phone batteries two to three hundred dollars or even higher, selling batteries and chargers more than make money selling mobile phone, if the unified model battery standards, White lost a large piece of the lucrative the market? Of course, this business has been the driving force to defend the status quo.

  Businessmen for the purpose of profit is the eternal law of the market, if not illegal, you can not blame them too. However, the norms of the law standard mobile phone battery that is long overdue and some of this may be the lack of it Why? — Our government departments to develop uniform technical standards for who to blame on this issue.

  The essence of a market economy through the market mechanism to achieve the social optimal allocation of resources, but the market system’s inherent flaws — “externalities” (the competitive market practices led to the negative social effects) and “free riders” (people accustomed to the enjoyment of certain public benefits system and not willing to bear the cost of it, as mentioned earlier in the cell phone battery waste and pollution to maintain silence) not season it is difficult to achieve this ideal state, which is the so-called “market failure.” Small cell phone battery was the problem of aggregation is “market failure” as another example. It is because of “market failure” before the need for government intervention. And this intervention the most legitimate and most effective way to intervene through legislation — the legislators to establish some kind of market activity in advance of the principles, rules or standards have forced market players to do the same in order to restrict competition “externalities” to overcome the public hp nc6120 battery, hp nc6140 battery, hp nc6200 battery “free-rider” weaknesses. Mobile phone batteries in question, our standard legislators “late,” the.

  Cell phone battery standard unified model, it is expected to be resolved through the market mechanism. I feel that unity is the standard cell phone battery cell phone manufacturers to market a great tool — if the handset manufacturers which take the lead in achieving the business models of mobile phones of all brands of generic batteries, it will certainly be favored by consumers.

  Of course, if mobile phone manufacturers do not intend to do so, our government departments on a hand: as soon as possible to develop and implement a mandatory cell phone battery standard models.

  Hopefully, our next-for-mobile phone, the battery will no longer have a charger 2 3 Total rubbish.

  PHS Machine Card Separation of a material change in the standard battery

  According to the latest news that, in the May 17 China Telecom and China Netcom in phases across the country to promote support for the separation of machine cards before the PHS handset, “separated from the phone card to test norms and technical requirements” changes have taken place in the larger . Among them, the consumers of particular importance is the battery of a change in design standards, changes in the standard battery design effectively avoids the problems brought about by, for PHS Machine Card Separation of the final maturity of significant security applications.

  Experts in the relevant industry standards, PIM / SIM card is not hot-swappable, remove the battery must be removable in order to PIM / SIM card, Once PIM / SIM card hot-plug operation, it is easy to lead to a non-identified cards, do not boot, auto shutdown, reboot show PIM / SIM card is not accepted, such as failure, the battery will result in the unreasonable design of the problems.

  The current market, PHS detachable battery mainly by the “wiring-type” and “contact-type” composed of two batteries, a “connection” type of battery connection, the shape of “the tail of the battery,” and in the replacement of PIM card often charged when the replacement, in fact, is a “hot swap” operation, current PIM card may be burned, it would greatly reduce battery life and cell phone itself. The use of “contact” type of hp nc6220 battery, hp nc6230 battery, hp nx6110 battery, hp nx6120 battery and hp nx6125 battery, users need to be replaced PIM card, you must first remove the battery, so that there will be no live PIM card plug, so this type of machine card separation PHS and GSM mobile phones on the replacement of permit There is no difference.

  It is learned that the operator has changed PHS Machine Card Separation test norms and technical requirements, ask the card must be separated from Little Smart “contact-style” battery; This means that all other norms do not meet all the new models are can not pass the test. Therefore, experts recommend purchasing card to pay special attention when PHS battery design.

  Rechargeable lithium batteries contain opportunities button

  Rechargeable lithium batteries contain opportunities button

  Button rechargeable lithium battery as an emerging power, the last two years in the wireless communications systems, electronic remote sensing equipment, personal mobile applications such as digital products more widely. With the mainland last year, many local dell battery manufacturers have to achieve the scale of mass production, production sales rose at the same time. The reporters found that the spot market to get involved button rechargeable lithium batteries are also areas of distributors rose, of which a large civilian market that specializes in rechargeable lithium batteries.

  Mr. Lu Huaqiang electronic world, dealers told the reporter that button rechargeable lithium batteries lithium batteries in the one-time based on the development of, small size, long life, no memory effect, lithium-ion battery is currently the main application button on the computer motherboard, MP3 watches, calculators, IC cards, electronic dictionaries and other products. Reporter was also informed that, in the Tax Machine, Bluetooth headsets, hand-cranked rechargeable flashlights, walkie-talkies and other toys products button rechargeable lithium batteries are widely used.

  It is understood that the last button rechargeable lithium battery market, largely by the Panasonic brand and South Korea occupy powercell, but in general a relatively high price, average 2 to 3 U.S. dollars to achieve. Since last year, many local manufacturers to achieve the scale of the volume of post-natal, currently on the market button rechargeable lithium batteries sold at 3 to 4 yuan, the price impact and the production and localization services to the domestic lithium battery rechargeable button to open the a large market.

  It is understood that the rechargeable lithium button rechargeable battery comparison of the nickel-cadmium and nickel metal hydride battery in the circuit design simple, long life, small size, performance, stability, and last button rechargeable lithium batteries are more optimistic about sales in 2005 will only further increase the market demand. Shenzhen Shan Mu Chen Battery Technology Co., Ltd., general manager of the military, said: “The price will be made to attract more designers and applications using rechargeable lithium batteries button program. Estimated demand this year will be 10 times the explosive growth.”

  Industry on the rechargeable lithium dell inspiron 4100 battery, dell inspiron 4150 battery, dell inspiron 8000 battery button showed optimism, the cash market the original operating civilian market for rechargeable lithium batteries distributor, since last year, there have been exploding lithium rechargeable incident, will be the goal towards the development of the rechargeable lithium button battery.
  It is reported that mass production will drive prices further reduce, when the button rechargeable lithium batteries is expected to low, 2 yuan, nickel-metal hydride or nickel cadmium battery more expensive button.

  Battery problems of small enterprises

  With the diversification of the development of household electrical appliances, the increasingly widespread use of battery consumption is also increasing the quality of their products has become a hot consumer concern. AQSIQ recently carried out on the battery product quality supervision and inspection results show that high market share of some of the larger sample of companies a pass rate of 100%. These enterprises to produce high-quality batteries, the quality and abroad fully comparable to the same well-known brand, cost performance is superior to imports of similar products; and some small businesses as a result of inadequate facilities, lack of technical strength, quality management and quality control is weak, poor product quality.

  The total sample of Hebei, Shanghai and other eight provinces and municipalities of the 31 enterprises 57 kinds of products, 47 kinds of qualified, product sampling rate of 82.5 percent qualified.

  Discharge capacity of the battery life is a measure of the size of the scale. The spot checks, there are nine kinds of products that failed in the discharge capacity of the project, and a far cry from the standards. The use of the harm caused by this product, many: First, the use of time is short, there may be a result of the use of leakage and damage to electrical appliances; Second, there is no deal as a result of used batteries scientific method the most economical, large-scale use of batteries would have a large number of unqualified spam of used batteries, adding to the pollution of the environment; Third, low efficiency in the use of low-quality batteries, spent a great deal of limited zinc, manganese resources, is not conducive to the sustainable development of the battery industry.

  Battery leakage resistance is a measure of performance over discharge the battery in the case of whether the fluid outlet of the indicators, zinc-manganese battery liquid leakage is acidic, alkaline zinc-manganese battery liquid leakage is a strong alkaline. The spot checks, there are two types on the 5th leakage-resistant properties of the battery failed. The reason is that the battery anode materials used in thin cylinders of zinc, manganese dioxide cathode material of high impurity content, the life of the dell inspiron 8100 battery, dell inspiron 8200 battery, dell latitude c500 battery discharge or too late will lead to perforation and leakage of zinc cylinder.

  Checks also found that six kinds of cells on the 5th, are small in diameter. Small cell diameter, will reduce the positive active filler may result in discharge capacity does not meet the standards. The reason for this is that some enterprises do not attach importance to the battery size, technical indicators, such as open circuit voltage test.

  In addition, the samples still exist in some cells there is no production date has no shelf life, non-implementation of the standard code, no site, no English warning that the battery is not marked, such as mercury content is not standardized. Some low-quality products and their list of Jiangmen City, Guangdong Province Deqiang Battery Co., Ltd. as small magic R6C Huadu District, Guangzhou, Yi Jian Jian Yi battery factory JIANYI R6C R03 Humen, Dongguan City, Guangdong Stars dell latitude c510 battery factory.
