要(yao)了(le)解36V锂电(dian)池的价格差异，首先要(yao)知(zhi)道(dao)如何生产(chan)36V锂电(dian)池。作为电(dian)池生产(chan)商，对于(yu)锂电(dian)池的效率来说，体积(ji)并不是越大(da)越好，相反，在一(yi)定程度上，合适的体积(ji)更有利于(yu)电(dian)池的性能。
一般(ban)来说，聚合物锂(li)电(dian)(dian)池的电(dian)(dian)压(ya)在(zai)3.2V到4.2V之(zhi)间(jian)比(bi)较常见，而(er)小型锂(li)电(dian)(dian)池，比(bi)如电(dian)(dian)子表的电(dian)(dian)压(ya)可能(neng)在(zai)1.2V到3.0V之(zhi)间(jian)。那么36V锂(li)电(dian)(dian)池就(jiu)会出现(xian)以(yi)下几种组合：
1、单排串联：如果一个电池(chi)的(de)电压是3.6V，那(nei)么就是要10个电池(chi)串联，所以(yi)价(jia)(jia)格是电池(chi)的(de)数(shu)量乘以(yi)电池(chi)的(de)单价(jia)(jia)加上(shang)加工成本再加上(shang)一定的(de)利润空(kong)间(jian)。
2、并联加串联：这种(zhong)(zhong)计算方式(shi)是(shi)一样的(de)，不(bu)同的(de)是(shi)这种(zhong)(zhong)方式(shi)是(shi)增(zeng)加容(rong)量，所需(xu)的(de)电(dian)池数量基本翻倍(bei)，所以价格会更贵(gui)。
因(yin)此，在购买(mai)36V锂电池时，要先(xian)了解(jie)自己的实际(ji)设备使(shi)用(yong)情况，再选择经济效益(yi)更好的电池。
聚合物锂电池容量低的原因(yin)有以(yi)下几点(dian)：
进料(liao)量小；极(ji)片两侧的材(cai)料(liao)含量差异较大；电(dian)解(jie)液(ye)少；电(dian)解(jie)液(ye)电(dian)导率(lv)低；正负(fu)极(ji)匹配(pei)不正确；隔(ge)膜孔隙率(lv)小；正负(fu)极(ji)材(cai)料(liao)比容量小等等。
聚合物锂电池内阻高(gao)的原因(yin)有以下几点：
负极(ji)(ji)与电(dian)极(ji)(ji)耳(er)虚(xu)焊；正极(ji)(ji)板(ban)与极(ji)(ji)耳(er)虚(xu)焊；正极(ji)(ji)耳(er)与盖(gai)帽(mao)虚(xu)焊；负极(ji)(ji)耳(er)与壳虚(xu)焊；铆(mao)钉(ding)与压(ya)板(ban)f内部接(jie)触电(dian)阻(zu)大，正极(ji)(ji)未加(jia)入(ru)导电(dian)剂；电(dian)池短(duan)路；隔膜纸孔(kong)隙率(lv)小等(deng)原因(yin)。
