目前，聚(ju)合物锂(li)电(dian)(dian)池的电(dian)(dian)解(jie)质是(shi)半固态的胶体(ti)(ti)和固体(ti)(ti)，而液(ye)体(ti)(ti)锂(li)离子电(dian)(dian)池的电(dian)(dian)解(jie)质是(shi)液(ye)体(ti)(ti)，两者(zhe)的外壳使用不同，那么(me)两者(zhe)还有哪些区别呢？
液(ye)体(ti)锂(li)离子电(dian)(dian)池(chi)和(he)聚(ju)合(he)(he)物(wu)(wu)锂(li)电(dian)(dian)池(chi)使用相(xiang)同的(de)(de)(de)正极(ji)和(he)负极(ji)材料(liao)，电(dian)(dian)池(chi)的(de)(de)(de)工作(zuo)(zuo)原理(li)基本相(xiang)同。一般采(cai)用LiCoO2作(zuo)(zuo)为正极(ji)，采(cai)用石(shi)墨(mo)等各种(zhong)碳材料(liao)作(zuo)(zuo)为负极(ji)，铝、铜作(zuo)(zuo)为流体(ti)收集器。主(zhu)要的(de)(de)(de)区(qu)别是电(dian)(dian)解液(ye)。锂(li)离子电(dian)(dian)池(chi)使用液(ye)态电(dian)(dian)解质(zhi)，而聚(ju)合(he)(he)物(wu)(wu)锂(li)电(dian)(dian)池(chi)使用聚(ju)合(he)(he)物(wu)(wu)电(dian)(dian)解质(zhi)，这种(zhong)聚(ju)合(he)(he)物(wu)(wu)可以是“固态的(de)(de)(de)”或“胶(jiao)体(ti)的(de)(de)(de)”，其中大多数目前使用聚(ju)合(he)(he)物(wu)(wu)胶(jiao)体(ti)电(dian)(dian)解质(zhi)。
1、安(an)全(quan)性(xing)：与金属(shu)壳液态锂离子电池(chi)(chi)相比(bi)，聚合物锂电池(chi)(chi)不会爆炸，只会气鼓，安(an)全(quan)性(xing)的(de)优势更适合容量(liang)为(wei)1-10Ah的(de)电池(chi)(chi)。
2、厚度(du)：普(pu)通锂离子(zi)电(dian)池由一个外壳(qiao)制成，然后加上正负端子(zi)。如果要求厚度(du)不超过(guo)3.6mm，那么液(ye)态锂离子(zi)电(dian)池就(jiu)会成为(wei)技术瓶颈。而聚(ju)合物(wu)锂电(dian)池可以达(da)到0.6mm。
3、容量：聚合物锂(li)电(dian)池容量高(gao)于液态锂(li)离(li)子电(dian)池10-15%。

锂(li)(li)电(dian)(dian)池(chi)的使用越(yue)来(lai)越(yue)广(guang)泛。很多朋友经常会问(wen)，三(san)元(yuan)(yuan)锂(li)(li)电(dian)(dian)池(chi)好不(bu)好？磷酸铁(tie)锂(li)(li)电(dian)(dian)池(chi)哪个更好？让我们具体比(bi)较一(yi)下：三(san)元(yuan)(yuan)锂(li)(li)电(dian)(dian)池(chi)全称为“三(san)元(yuan)(yuan)材料锂(li)(li)离子(zi)电(dian)(dian)池(chi)”，一(yi)般(ban)指使用锰(meng)(meng)酸镍钴(gu)锂(li)(li)或铝酸镍钴(gu)（NCA）三(san)元(yuan)(yuan)正极材料的锂(li)(li)电(dian)(dian)池(chi)。镍盐、钴(gu)盐和锰(meng)(meng)盐按三(san)种不(bu)同的成分比(bi)例(li)进(jin)行(xing)不(bu)同的

20世纪80年代首次推出(chu)的充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)器(qi)芯片，由于化(hua)学物质电(dian)(dian)(dian)(dian)(dian)池(chi)难以(yi)充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)，简化(hua)了NiCd和(he)NiMH充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)器(qi)的设计。锂离(li)子电(dian)(dian)(dian)(dian)(dian)池(chi)更简单，而且大多(duo)数现代充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)芯片还包(bao)括(kuo)为锂离(li)子电(dian)(dian)(dian)(dian)(dian)池(chi)安(an)全充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)所需的保护电(dian)(dian)(dian)(dian)(dian)路，其(qi)他(ta)包(bao)括(kuo)电(dian)(dian)(dian)(dian)(dian)流和(he)电(dian)(dian)(dian)(dian)(dian)压(ya)调整，FET开关，一些充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)状态指示灯和(he)电(dian)(dian)(dian)(dian)(dian)池(chi)平衡。
