聚合物锂离子电池可分为三类,具体如下:
1、固体聚合物电解(jie)质锂离子(zi)(zi)电池。电解(jie)质是聚合物和(he)盐的(de)混合物。该(gai)电池室温(wen)(wen)下离子(zi)(zi)电导率低,可应(ying)用于高(gao)温(wen)(wen)环境下。
2、凝胶聚(ju)合物(wu)(wu)电解质锂离子电池。即(ji)在固体聚(ju)合物(wu)(wu)电解质中加(jia)入增塑剂(ji)等(deng)添加(jia)剂(ji),以提高离子电导(dao)率(lv),一(yi)般(ban)应用于常(chang)温环境下。
3、聚合物正极材(cai)(cai)料(liao)(liao)锂离子电池(chi)。它采用导电聚合物作为正极材(cai)(cai)料(liao)(liao),比能(neng)量是现有锂离子电池(chi)的3倍,是新一(yi)代锂离子电池(chi)。
新一代聚(ju)(ju)合物锂离子(zi)(zi)电池(chi)(chi)(chi)在聚(ju)(ju)合程度(du)(du)上已经很(hen)高(gao)(gao)了,所以(yi)形(xing)状(zhuang)可以(yi)很(hen)薄(厚(hou)度(du)(du)为0.5 mm)、任(ren)意(yi)面积和任(ren)意(yi)形(xing)状(zhuang),大(da)大(da)提高(gao)(gao)了电池(chi)(chi)(chi)设计的灵活性,从而(er)满足(zu)产品(pin)需求,做出任(ren)意(yi)形(xing)状(zhuang)和容(rong)量(liang)的电池(chi)(chi)(chi)。同(tong)时,聚(ju)(ju)合物锂离子(zi)(zi)电池(chi)(chi)(chi)的单(dan)位能量(liang)比(bi)目前的一般(ban)锂离子(zi)(zi)电池(chi)(chi)(chi)高(gao)(gao)出50%,其容(rong)量(liang)、充放(fang)电特性、安全性、工作温度(du)(du)范围、循环(huan)寿命和环(huan)境性能都比(bi)锂离子(zi)(zi)电池(chi)(chi)(chi)显著(zhu)提高(gao)(gao)。
