摘要
近年来,锂离子电池因其优异的特性,发展十分迅速。锂离子电池的优异性能与电池的材料选择,材料的制备工艺等密切相关。正极材料LiMn2O4是近几年锂离子电池研究的热点,但其在循环过程中的容量衰减是制约锂离子电池商品化的关键。本文介绍了不同正极材料的结构、电化学性能、研究现状,侧重于阐述控制锂离子电池循环过程中可逆嵌锂容量和稳定性的嵌锂电极材料的结构性质。
Recent development in electronics and portable devices requires light weight, compact, high energy density batteries. Lithium ion battery is the right one for the demand, as it exhibits excellent properties such as higher cell voltage, higher energy density, longer shelf life and broader working temperature as compared to other rechargeable batteries. These properties correlate with what materials the batteries are made of the research on lithium ion battery has focused on positive material LiMn204 over the...
