一、聚合物電芯是什么意思
聚合物電芯也是(shi)鋰(li)離子(zi)電(dian)池的一種組(zu)成(cheng)部分。鋰(li)離子(zi)二次充電(dian)電(dian)池的組(zu)成(cheng)是(shi)這樣的:電(dian)芯(xin)+保護電(dian)路板。
充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)去除保(bao)護電(dian)(dian)(dian)(dian)(dian)路板就是電(dian)(dian)(dian)(dian)(dian)芯了。它是充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)中的(de)蓄電(dian)(dian)(dian)(dian)(dian)部分。電(dian)(dian)(dian)(dian)(dian)芯的(de)質(zhi)量直接決定了充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)質(zhi)量。聚合物電(dian)(dian)(dian)(dian)(dian)芯與(yu)傳統鋰(li)離子(zi)電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)區別在于生產工(gong)藝。鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)是纏(chan)繞而成(cheng),體積(ji)較軟。聚合物是疊加而成(cheng),體形較硬。相(xiang)同(tong)體積(ji)的(de)聚合物和鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi),聚合物的(de)容量更大,約高出30%以上。并且更安(an)全,爆炸(zha)風險小。
二、聚合物電芯有什么特性
移(yi)動電(dian)源(yuan)電(dian)芯(xin)主要(yao)分為有18650電(dian)芯(xin)、聚(ju)合(he)物電(dian)芯(xin)2種,其中聚(ju)合(he)物電(dian)芯(xin)的(de)優勢在于(yu)續航能力強,容(rong)量大,聚(ju)合(he)物電(dian)芯(xin)具體(ti)特性(xing)如下:
1、在于外(wai)(wai)型(xing)制作多樣性,而(er)采用了18650電(dian)池的產品厚而(er)大,以及千年不變(bian)的外(wai)(wai)形。
2、使用(yong)壽(shou)命長(chang)。充(chong)放電達到(dao)了(le)500次以上沒有問題(ti)。
3、使用安全性高,多應用于高端產品之中。聚合物電芯安全(quan)性體現在不(bu)會發生爆炸,僅可能出(chu)現鼓(gu)包、自燃等情(qing)況。
4、容量高,在(zai)同樣的(de)包裝體(ti)(ti)積下(注意,是包裝體(ti)(ti)積),聚合物電芯能夠存儲更(geng)多(duo)的(de)電量,故而它們多(duo)數更(geng)輕更(geng)薄,具備不錯的(de)便攜性,直(zhi)接改善了用(yong)戶的(de)使用(yong)體(ti)(ti)驗。
5、聚(ju)合(he)物(wu)電芯(xin)的(de)成(cheng)(cheng)本(ben)高,和其他電池相(xiang)比,聚(ju)合(he)物(wu)電池的(de)成(cheng)(cheng)本(ben)幾乎是最高的(de),而(er)且(qie)是集中在難(nan)以降低的(de)電解液上面,高成(cheng)(cheng)本(ben)成(cheng)(cheng)了制約聚(ju)合(he)物(wu)電池發展(zhan)的(de)重大因數(shu)。
