聚合物电池化学

2023-05-23



锂离(li)子电池(chi)(chi)包(bao)括液体锂离(li)子电池(chi)(chi)（LIB）和(he)锂聚合(he)物电池(chi)(chi)（PLIB）。其中，液态锂离(li)子电池(chi)(chi)是指嵌入式负极(ji)二次电池(chi)(chi)。使用锂化合(he)物LICOO2、LiniO2或(huo)Limn2O4，负极(ji)使用锂-碳间化合(he)物LIXC6。典型的蓄电池(chi)(chi)系统是：


（-）C|Lipf6 EC+12c|LICOO2（+）


阳性反(fan)应：LICOO2=li1-xCoo2+xli++xe-


阴性反应(ying)：6C+XLI++XE-=lixc6


电池总响应(ying)：LICOO2+6C=li1-xCoo2+lixc6


锂聚(ju)(ju)合物电池的(de)原(yuan)理与(yu)液态锂相同，主要区(qu)别在于电解(jie)质与(yu)液态锂不同。电池的(de)主要结(jie)构包括三个元素(su)：正极(ji)、负极(ji)和电解(jie)质。所谓的(de)锂聚(ju)(ju)合物电池
