2、性能电池的代表。锂离子电池是新型绿色环保蓄电池，主要结构分为正极、负极、电解液、隔膜。当放电时，锂离子从负极释放出进入正极，充电时，锂离子从正极释放进入负极。与其他蓄电池相比，锂离子电池的主要优点是储能密度高(300400 kWh/m3，130 kWh/t)，储能效率高(接近 100%)和使用寿命长(每次放电不超过储能的 80%时可充 3 000 次 )。由于具有上述优点，锂离子电池得到快速发展，在几年之内锂电池已经占有小型移动设备电源市场份额的 60%以上。由于锂离子电池能量密度高，大规模集成后的安全性值得重点关注。这就需要从原材料的选用、单体电池结构的优化改进、制程过程的控制、电池管理系统
