一、聚合物電芯是什么意思

聚合物電芯也是鋰離子電(dian)池的一種組成部(bu)分。鋰離子二(er)次充電(dian)電(dian)池的組成是這樣的：電(dian)芯+保護電(dian)路板。

充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)去除保護(hu)電(dian)(dian)(dian)(dian)(dian)路板就是(shi)電(dian)(dian)(dian)(dian)(dian)芯了(le)。它是(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)中的(de)(de)蓄(xu)電(dian)(dian)(dian)(dian)(dian)部(bu)分(fen)。電(dian)(dian)(dian)(dian)(dian)芯的(de)(de)質(zhi)量直(zhi)接(jie)決(jue)定了(le)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)質(zhi)量。聚(ju)合(he)物(wu)(wu)電(dian)(dian)(dian)(dian)(dian)芯與傳統(tong)鋰(li)離子電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)區別在(zai)于生產(chan)工藝。鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)是(shi)纏繞(rao)而成(cheng)，體(ti)(ti)積較軟。聚(ju)合(he)物(wu)(wu)是(shi)疊加而成(cheng)，體(ti)(ti)形較硬(ying)。相同體(ti)(ti)積的(de)(de)聚(ju)合(he)物(wu)(wu)和(he)鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)，聚(ju)合(he)物(wu)(wu)的(de)(de)容量更大，約高出30%以上。并且更安(an)全(quan)，爆炸風險小(xiao)。

二、聚合物電芯有什么特性

移(yi)動(dong)電(dian)源(yuan)電(dian)芯(xin)(xin)主要分(fen)為有(you)18650電(dian)芯(xin)(xin)、聚合(he)物電(dian)芯(xin)(xin)2種，其中(zhong)聚合(he)物電(dian)芯(xin)(xin)的優(you)勢(shi)在(zai)于續航能力強，容(rong)量大，聚合(he)物電(dian)芯(xin)(xin)具體(ti)特性如下：

1、在于外型制作多(duo)樣(yang)性，而(er)采(cai)用了18650電池的(de)產(chan)品厚而(er)大，以及千(qian)年不變的(de)外形。

2、使用壽命長。充放電達到(dao)了500次(ci)以上(shang)沒(mei)有(you)問題。

3、使用安全性高，多應用于高端產品之中。聚合物電芯安全性體現在不(bu)會發生爆炸，僅可能出現鼓(gu)包(bao)、自燃(ran)等情況。

4、容量(liang)高，在同樣的包(bao)裝體積下(xia)（注意(yi)，是(shi)包(bao)裝體積），聚合物電芯能夠存儲更多的電量(liang)，故而它們多數更輕更薄，具備(bei)不(bu)錯的便(bian)攜(xie)性，直(zhi)接改善(shan)了用(yong)戶的使(shi)用(yong)體驗。

5、聚(ju)合物(wu)電(dian)(dian)芯的(de)(de)(de)成(cheng)本高，和其他電(dian)(dian)池(chi)相(xiang)比(bi)，聚(ju)合物(wu)電(dian)(dian)池(chi)的(de)(de)(de)成(cheng)本幾乎是最高的(de)(de)(de)，而且是集中(zhong)在難(nan)以降(jiang)低的(de)(de)(de)電(dian)(dian)解液上面，高成(cheng)本成(cheng)了制約聚(ju)合物(wu)電(dian)(dian)池(chi)發展的(de)(de)(de)重大因數。
