日本锂离子蓄电池技术的开发过程和最新趋势

锂离子蓄电池已被广泛应用于蜂窝移动电话、笔记本电脑及摄录像一体机等便携式电器的电源。这种新型电池体系的研究和开发工作始于 1981年 ,其起源是对采用电子导电聚合物———聚乙炔作为负极材料的锂蓄电池的开发。此后 ,研究的重点从聚乙炔转移到具有同样的 pi电子的碳材料上。在含锂离子的金属氧化物LiCoO2 被采用为正极材料后 ,锂离子蓄电池终于开发成功。在锂离子蓄电池实现商品化生产后 ,许多相应的技术也被开发出来 ,而这些新技术将会提高锂离子蓄电池的性能。

Developing process and the latest trend for lithium-ion battery technology in Japan

Lithium ion battery has been widely used for cellular phones, notebook personal computers and camcoders. Reseasch and development of this new battery system were started at 1981 and the origin of the research on secondary battery using an electronic conductive polymer, poly acetylene, as the negative electrode. Then the focus was shifted from polyacetylene to carbonaceous material, which have the same pi electrons. Lithium ion battery was born by combining with a lithium ion containing metal oxide, LiCoO 2 as the positive electrode. After commercialization of lithium ion battery, various improvement technologies have been developed. These new techologies will improve the performance of lithium ion battery in future.
