2、CoO2+6C=Li(1-x)CoO2+LixC6 充放电反应机理为锂离子在正负极材料之间的嵌入和脱嵌锂电池分类锂电池分类4锂离子电池锂离子电池具有以下优点：电压高，单体电池的工作电压高达3.6-3.9V，是Ni-Cd、Ni-H电池的3倍比能量大，目前能达到的实际比能量为100-145 mAh/g（2倍于Ni-Cd，1.5倍于Ni-MH） 循环寿命长,一般均可达到500次以上,甚至1000次以上.安全性能好,无公害,无记忆效应可快速充放电，1C充电是容量可以达到标称容量的80%以上。工作温度范围高，工作温度为-2555C。锂离子电池也存在着一定的缺点，如： 电池成本较高。主要表现在正极材料Li

3、CoO2的价格高（Co的资源较少），电解质体系提纯困难。大电流放电困难。由于有机电解质体系等原因，电池内阻相对其他类电池大。故要求较小的放电电流密度，一般放电电流在0.5C以下，适合于中小电流的电器使用。需要保护线路控制。锂电池分类锂电池分类5锂金属原电池锂金属原电池具有以下优点：比能量较锂离子电池高，比能量达200-400 mAh/g，单体工作电压2.8-3.2V或3.2-3.4v，性能稳定，自放电小，可大电流放电贮存寿命长，室温下可以贮存10年以上使用温度范围广，一般为-2060度和-5585C高安全性，高可靠性，放电电压平稳，无公害锂二氧化锰是比较常用的一款锂金属原电池，其正极活性物质二
