一、圆柱锂电(dian)池生(sheng)产极片错位与锥形的原因
1、卷针是否同心；
2、卷针与基板(ban)不垂直；
3、极片导板与基板不垂直平行；
4、极片的后过(guo)渡辊(gun)与基板(ban)不垂(chui)直；
5、来料波浪边太严重。
二(er)、圆柱锂电(dian)池生产极片错位与锥形的维修方法
1、等量3.5、4*100圆轮钢与线圈针套(tao)的同心度(du)，精(jing)度(du)误差为10um；
2、同心(xin)度测(ce)量完成后，垂直测(ce)量工具和直角尺是(shi)用来测(ce)量的垂直卷针和大(da)板的垂直度(至少保证(zheng)两个(ge)方(fang)向的垂直)；
3、确保(bao)电极导流板和基板的垂直度和并行性；
4、用(yong)直(zhi)角尺校准(zhun)过极(ji)片后(hou)过渡辊的垂(chui)(chui)直(zhi)度；（如果(guo)辊确实(shi)与基板不垂(chui)(chui)直(zhi)，则可以(yi)加垫片直(zhi)到垂(chui)(chui)直(zhi)，并打上记号(hao)；注：万不得已，不得加垫片乱垫）
5、更换极片。

锂(li)(li)电(dian)(dian)(dian)池的价(jia)格(ge)因品牌、型号、容(rong)量、制(zhi)造工艺等因素而异(yi)。一般(ban)来说，锂(li)(li)电(dian)(dian)(dian)池的价(jia)格(ge)与它的容(rong)量和电(dian)(dian)(dian)压有(you)关。例如(ru)(ru)，如(ru)(ru)果(guo)一种锂(li)(li)电(dian)(dian)(dian)池的电(dian)(dian)(dian)压是3.6伏特(te)，而它的容(rong)量是1000毫安时，那么(me)它的价(jia)格(ge)可(ke)能在100美(mei)元到150美(mei)元之(zhi)间(jian)。如(ru)(ru)果(guo)一种锂(li)(li)电(dian)(dian)(dian)池的电(dian)(dian)(dian)压是4.2伏特(te)，而它的容(rong)量是2000毫安时，那么(me)它的价(jia)格(ge)可(ke)能在150美(mei)元到200美(mei)元之(zhi)间(jian)。需...
