电动车与航天用锂离子蓄电池的进展

Progress in lithium ion battery for EV and spacecraft applications

锂离子蓄电池作为一种９０年代初期发展起来的先进蓄电池，具有高比能量、高电压、长寿命和无记忆效应等特点，七年来的商品应用表明，电池的安全性和实用性均好。根据大容量电池近年来的试验结果与分析，液体电解质常温锂离子蓄电池很有可能被选为电动车、航天和储能用电源，并显示其优异的特性。本文收集并报道了国内外研究机构、电池厂商在此领域的研究成果。同时，也简单介绍了中国天津电源研究所在国家发展计划委员会资助下，对电动车用大容量锂离子蓄电池研究的初步结果。

Lithium ion battery as an advanced rechargeable battery began to produce in early90, which has following advantages including high energy and power density, long cycle life, high cycle efficiency and no memory effect. About seven years have passed since its commercialization,it shows good safety and characteristics. According to recent test use and analysis, the ambient temperature lithium ion battery using liquid electrolyte appears to be the most promising system for EV, spacecraft and energy storage applications today. This paper reports the latest results of several institutes and companies at home and abroad in this area. At same time, the preliminary results of China Tianjin Institute of Power Sources are also briefly introduced on lithium ion battery for EV with funding from the National Committee of Development and Planning.
