聚合(he)物锂(li)电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)特殊之(zhi)处在于其电(dian)(dian)(dian)(dian)解(jie)(jie)质(zhi)(zhi)不(bu)同于其他传统的(de)锂(li)电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。传统的(de)锂(li)电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)使用液(ye)体(ti)电(dian)(dian)(dian)(dian)解(jie)(jie)质(zhi)(zhi)，而聚合(he)物锂(li)电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)使用新(xin)的(de)固体(ti)电(dian)(dian)(dian)(dian)解(jie)(jie)质(zhi)(zhi)，但是(shi)(shi)阴极(ji)材(cai)料和阳极(ji)材(cai)料是(shi)(shi)一样(yang)的(de)。锂(li)电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)液(ye)体(ti)电(dian)(dian)(dian)(dian)解(jie)(jie)质(zhi)(zhi)由固体(ti)电(dian)(dian)(dian)(dian)解(jie)(jie)质(zhi)(zhi)所取代，即就是(shi)(shi)聚合(he)物锂(li)电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，它(ta)们可以被制(zhi)成(cheng)任何形(xing)状。电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)外壳(qiao)采用传统的(de)轻量化外壳(qiao)，整(zheng)个(ge)电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)能量由一个(ge)高密(mi)度(du)的(de)钢壳(qiao)或铝壳(qiao)电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)和一层铝塑复(fu)合(he)膜控制(zhi)。因(yin)此(ci)，锂(li)聚合(he)物电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是(shi)(shi)由高分子固体(ti)电(dian)(dian)(dian)(dian)解(jie)(jie)质(zhi)(zhi)组成(cheng)的(de)，其成(cheng)本(ben)远远高于液(ye)态(tai)电(dian)(dian)(dian)(dian)解(jie)(jie)质(zhi)(zhi)锂(li)电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，是(shi)(shi)目(mu)前智能设备(bei)、手机、平(ping)板电(dian)(dian)(dian)(dian)脑以及(ji)模型飞(fei)机、汽车(che)、无人机等可穿(chuan)戴设备(bei)所使用的(de)电(dian)(dian)(dian)(dian)池(chi)(chi)(chi)之(zhi)一。

聚(ju)合(he)(he)物(wu)锂(li)(li)电(dian)池(chi)在(zai)(zai)充电(dian)过(guo)程中容(rong)(rong)易发(fa)生短路，包(bao)括内(nei)部(bu)短路和(he)外(wai)部(bu)短路。但是现(xian)在(zai)(zai)大(da)多(duo)数锂(li)(li)离子电(dian)池(chi)都(dou)有(you)(you)防短路保护(hu)功(gong)能(neng)，在(zai)(zai)很多(duo)情(qing)况下，这种保护(hu)电(dian)路可能(neng)在(zai)(zai)各种情(qing)况下都(dou)不起(qi)作用，而且在(zai)(zai)接线时只能(neng)起(qi)到有(you)(you)限的(de)防短路作用。如果充电(dian)时间(jian)过(guo)长(zhang)，锂(li)(li)聚(ju)合(he)(he)物(wu)电(dian)池(chi)更有(you)(you)可能(neng)膨(peng)胀。锂(li)(li)具有(you)(you)很强的(de)化(hua)学性质(zhi)，很容(rong)(rong)易燃烧。在(zai)(zai)活(huo)化(hua)过(guo)程中，内(nei)部(bu)压力增(zeng)加到一(yi)定的(de)压力水(shui)平，产生的(de)气体膨(peng)胀。如果外(wai)壳(qiao)被划伤，它(ta)就(jiu)会(hui)破裂发(fa)生火灾和(he)爆炸。由于生产要求高(gao)，聚(ju)合(he)(he)物(wu)电(dian)解质(zhi)系统的(de)清洁难度大(da)，成本相对(dui)较(jiao)高(gao)。
