Battery Laptop Rechargeable: The safety of lithium-ion battery materials

The safety of lithium-ion battery materials

More than 10 years ago, the lithium-ion canon nb-4l battery is only scientists in the laboratory sought-after piece of scholarship.

Today, the people’s lives almost without it. Mobile phones, portable computers, almost all portable personal electronic equipment must be relied on to provide the required energy.

But how to put it in the car, and became a driving force of motor vehicles; how to access it to become the future power of the “container”, the scientists began to explore constantly, the battery “magnanimous” to a growing, dynamic to Yue Lai is stronger, life expectancy should be longer, but it does not mean that the size and weight but also growing, this is not simply the number of overlay .

The key to this change is that the casio np-20 battery material. The materials used in mobile phone battery must not be used to make electric cars the “heart”, or is not likely to explode, but will certainly be trouble.

Thus, scientists from various countries are trying to find the best answer.

20 years, insisted that something out of nothing

Physics Chinese Academy of Sciences research fellow and doctoral tutor Huang Xue-Jie evaluation of the development of China’s lithium-ion batteries are: from scratch, from small to large, developed rapidly.

In 2000 China’s output of about 20 million, accounting for 3.6% global share, with South Korea close to a time when Japan had reached an annual output of 512 million, accounting for 93.9%. 2002 China crossed the 100 million in 2004 reached 760 million, accounting for 37.1% of the global casio np-100 market, after Japan.

China’s lithium-ion battery research and development projects has been the focus of 863 items, from mobile devices with small batteries started 20 consecutive years of support. At present a small lithium-ion battery has an annual production capacity of more than 200 million, Japan, SONY, Sanyo and other companies to build production plants to China. Most of these materials achieve localization and the introduction of multi-national has been self-built production lines and supporting materials factory, there are many months, have been the formation of large-scale production and market competition.

“Small battery and its related materials, current technology processes mature into the scale of production, mainly to promote industrial investment.” Wong Hok-chieh.

“China’s power battery research relatively late, but so far has made remarkable achievements.” Huang Xue-Jie said that after 20 years of Physics, Chinese Academy of Sciences to study the accumulation of storage in nano-phosphate lithium anode materials and cathode minolta np-600 materials research in China ranks world-class.

China’s power type lithium-ion batteries “15″ electric vehicles during the 863 major projects with the support of research and development began to address the issue of high power output, security has also been greatly improved, relying on the CAS Institute of Physics Technology Suzhou Star Constant Power Co., created to achieve a flat battery mechanized production, in 2004, Suzhou Star Constant R & D of 10 AH high-energy-type and 7.5 Ah high-power-type manganese lithium-ion battery has passed the United States UL safety test, becoming the first Chinese mainland by a UL-certified Li-ion power battery, the current bulk supply of products have been domestic and international markets. The development of 15 high-power battery, when an electric vehicle 863 major projects through the organization’s unity test, “15″ period has been successfully applied to the fuel cell sony np-f970 hybrid electric car concept car “Beyond II” and “Beyond the Three.” When an eight high-power battery has become the “Shanghai” brand fuel cell hybrid car standard.

“Car lithium-ion battery technology development and other high-end products, not just the development of China’s electric car industry needs, will also bring China’s lithium-ion digital camera battery industry, a comprehensive technical upgrades.” Wong Hok-chieh.
