一、聚合物電芯是什么意思
聚合物電芯也是鋰(li)離子電(dian)池的一種組成部分(fen)。鋰(li)離子二次充電(dian)電(dian)池的組成是這樣的:電(dian)芯+保護(hu)電(dian)路(lu)板。
充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)去除保護電(dian)(dian)(dian)(dian)路板就是電(dian)(dian)(dian)(dian)芯了。它(ta)是充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)中的蓄電(dian)(dian)(dian)(dian)部(bu)分。電(dian)(dian)(dian)(dian)芯的質量(liang)直接決定了充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的質量(liang)。聚(ju)合(he)物(wu)(wu)電(dian)(dian)(dian)(dian)芯與傳統鋰(li)(li)(li)離(li)子電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的區別在于生產工藝。鋰(li)(li)(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是纏繞而成,體(ti)積(ji)較(jiao)軟。聚(ju)合(he)物(wu)(wu)是疊加而成,體(ti)形較(jiao)硬。相同體(ti)積(ji)的聚(ju)合(he)物(wu)(wu)和鋰(li)(li)(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi),聚(ju)合(he)物(wu)(wu)的容量(liang)更(geng)大,約高出30%以上。并且更(geng)安全(quan),爆炸風險小。
二、聚合物電芯有什么特性
移動電(dian)(dian)源電(dian)(dian)芯(xin)主要分(fen)為有18650電(dian)(dian)芯(xin)、聚合(he)物(wu)電(dian)(dian)芯(xin)2種,其(qi)中聚合(he)物(wu)電(dian)(dian)芯(xin)的優勢在(zai)于續(xu)航能力(li)強,容量大,聚合(he)物(wu)電(dian)(dian)芯(xin)具體特性如下(xia):
1、在于外型(xing)制作(zuo)多樣性,而采(cai)用了18650電(dian)池(chi)的產品厚而大,以及(ji)千(qian)年不(bu)變(bian)的外形。
2、使用壽命長。充放電達到了(le)500次(ci)以(yi)上(shang)沒有問題。
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(xing)體現在不會發生爆炸,僅(jin)可能出現鼓包、自燃等情況(kuang)。
4、容量高,在同樣的包(bao)(bao)裝(zhuang)體積下(注意(yi),是包(bao)(bao)裝(zhuang)體積),聚合物(wu)電芯能夠存儲更多的電量,故(gu)而它(ta)們多數(shu)更輕更薄,具備不錯的便(bian)攜性(xing),直(zhi)接改善了用戶的使(shi)用體驗。
5、聚(ju)合物電(dian)芯的(de)成本(ben)高,和其他(ta)電(dian)池相比,聚(ju)合物電(dian)池的(de)成本(ben)幾乎是(shi)最高的(de),而且是(shi)集中在難以降(jiang)低的(de)電(dian)解液上面,高成本(ben)成了制(zhi)約(yue)聚(ju)合物電(dian)池發展(zhan)的(de)重大因數。
