動(dong)力(li)電(dian)(dian)(dian)池(chi)(chi)作(zuo)為純電(dian)(dian)(dian)動(dong)汽車的(de)＂心臟＂，純電(dian)(dian)(dian)動(dong)汽車的(de)關鍵在(zai)于(yu)(yu)動(dong)力(li)電(dian)(dian)(dian)池(chi)(chi)。對(dui)于(yu)(yu)動(dong)力(li)電(dian)(dian)(dian)池(chi)(chi)而言，動(dong)力(li)電(dian)(dian)(dian)池(chi)(chi)性(xing)能指(zhi)標(biao)，容(rong)量(liang)(liang)，使(shi)用(yong)(yong)壽命等，都是用(yong)(yong)來衡量(liang)(liang)電(dian)(dian)(dian)池(chi)(chi)的(de)性(xing)能指(zhi)標(biao)之一，電(dian)(dian)(dian)池(chi)(chi)在(zai)長(chang)期(qi)使(shi)用(yong)(yong)過程當中，電(dian)(dian)(dian)池(chi)(chi)容(rong)量(liang)(liang)等會隨著使(shi)用(yong)(yong)的(de)時間而降低，作(zuo)為電(dian)(dian)(dian)池(chi)(chi)來說，循環次數(shu)和(he)電(dian)(dian)(dian)池(chi)(chi)有什么關系？

循環次(ci)數指的是電(dian)(dian)池在(zai)使(shi)用(yong)時(shi)候的時(shi)間和(he)次(ci)數，換句話來(lai)說(shuo)那么也就是電(dian)(dian)池在(zai)充(chong)(chong)滿(man)(man)以后(hou)，然后(hou)又把電(dian)(dian)池換光了，然后(hou)再充(chong)(chong)滿(man)(man)，在(zai)放(fang)光，然后(hou)在(zai)充(chong)(chong)滿(man)(man)反復(fu)循環。對于動力(li)電(dian)(dian)池來(lai)說(shuo)，一個完(wan)整充(chong)(chong)放(fang)電(dian)(dian)過程才是一個循環，根據這個東西來(lai)看，電(dian)(dian)池都是有循環次(ci)數的。

根(gen)據(ju)三元鋰(li)電(dian)池(chi)的(de)使用(yong)壽(shou)命來說，電(dian)池(chi)的(de)使用(yong)壽(shou)命是在1500到2000次(ci)(ci)(ci)左右的(de)循(xun)(xun)環(huan)次(ci)(ci)(ci)數(shu)，而這一(yi)循(xun)(xun)環(huan)次(ci)(ci)(ci)數(shu)，會隨著電(dian)池(chi)在使用(yong)過程(cheng)當中出現變少的(de)情(qing)況，循(xun)(xun)環(huan)次(ci)(ci)(ci)數(shu)減(jian)少，意味著電(dian)池(chi)的(de)使用(yong)壽(shou)命也(ye)是在不(bu)斷的(de)減(jian)少，在使用(yong)的(de)過程(cheng)中，由(you)于電(dian)池(chi)的(de)循(xun)(xun)環(huan)次(ci)(ci)(ci)數(shu)在不(bu)斷的(de)減(jian)少，那么(me)也(ye)就意味著鋰(li)電(dian)池(chi)內部(bu)會發生不(bu)可逆的(de)電(dian)化學反(fan)應(ying)導致容(rong)量下(xia)降(jiang)。

總結：鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)生命循(xun)環次數(shu)是(shi)根(gen)據(ju)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)質(zhi)量和(he)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)材料來定(ding)，鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)循(xun)環次數(shu)和(he)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)之(zhi)間的(de)使用(yong)壽(shou)命之(zhi)類的(de)是(shi)密不可分的(de)聯系。每(mei)完成(cheng)一個循(xun)環次數(shu)，對于電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)容量來說(shuo)就會(hui)(hui)減少(shao)一點，相(xiang)對于電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)使用(yong)壽(shou)命也會(hui)(hui)減少(shao)。
