如何区分检验聚合物软包锂电池的方法

2022-03-18

如何区分检验聚合物软包锂电池的方法

一、从优点方面区分(fen)聚合(he)物软包(bao)锂电(dian)池

1、用固(gu)体电(dian)解质(zhi)代替原来的(de)液体电(dian)解质(zhi);

2、用锂离子(zi)负极(ji)材料代替碳负极(ji)材料;

3、重量轻、超薄;

4、形状灵活:可根据(ju)用户需(xu)要(yao)制成不同的(de)形状;

5、安全性提升:即使过充也很稳定。由(you)于电解质是固体,泄漏的机会变得非常小。

二、从外包(bao)装(zhuang)和(he)内部组(zu)成区分聚合物软(ruan)包(bao)锂(li)电池

1、片(pian)状:如(ru)果外面用(yong)贴纸包着,先(xian)用(yong)两(liang)只手来回掰几下。如(ru)果侧面有(you)塑料框架,那么它可(ke)能是(shi)一般锂离子电(dian)池(chi)(chi),而不是(shi)聚(ju)(ju)合物。如(ru)果电(dian)池(chi)(chi)的边缘是(shi)弯曲的,并且(qie)覆层板中有(you)间隙,则它可(ke)能是(shi)聚(ju)(ju)合物软包锂电(dian)池(chi)(chi)。

2、桶(tong)形:通常锂离子含量(liang)较多,聚合物较少(shao)。聚合物大(da)多是扁平的。

三、从产品属性方(fang)面(mian)区分(fen)聚合物软(ruan)包(bao)锂(li)电池

聚合(he)物软(ruan)包锂(li)(li)电(dian)(dian)池(chi)是锂(li)(li)离子电(dian)(dian)池(chi)的(de)一种(zhong),但与液态(tai)锂(li)(li)(Li-ion)电(dian)(dian)池(chi)相比(bi),它具有(you)能量密度(du)高(gao)、体积更小(xiao)、超(chao)薄、重量轻、安全(quan)性高(gao)等诸多优点(dian)。在外形(xing)上,聚合(he)物电(dian)(dian)池(chi)具有(you)超(chao)薄的(de)特(te)性,可以(yi)(yi)根据不同产(chan)品的(de)需要,制成任意(yi)形(xing)状和(he)容量的(de)电(dian)(dian)池(chi)。这种(zhong)电(dian)(dian)池(chi)可以(yi)(yi)达(da)到的(de)小(xiao)厚度(du)可达(da)0.5毫米。
