'''磷酸铁锂电池'''，是一种使用磷酸铁锂（LiFePO4）作为正极材料，碳作为负极[[材料]]的锂离子电池，单体额定电压为3.2V，充电截止电压为3.6V~3.65V。

充电过程中，磷酸铁锂中的部分锂离子脱出，经电解质传递到负极，嵌入[[负极碳材料]]；同时从正极释放出电子，自外电路到达负极，维持化学反应的平衡。放电过程中，锂离子自负极脱出，经电解质到达正极，同时负极释放电子，自外电路到达[[正极]]，为外界提供能量。

磷酸铁锂电池具有工作电压高、[[能量密度大]]、[[循环寿命长]]、[[安全]]性能好、自放电率小、[[无记忆效应]]的优点。<ref>[https://wenku.so.com/d/0f7f364b9418a917514fd8e988c87d0d 磷酸铁锂电池优缺点分析],360文库 , 2020年11月25日</ref>
