動(dong)(dong)力電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)作(zuo)為純電(dian)(dian)(dian)動(dong)(dong)汽(qi)車(che)(che)的(de)＂心臟＂，純電(dian)(dian)(dian)動(dong)(dong)汽(qi)車(che)(che)的(de)關(guan)(guan)鍵(jian)在(zai)于動(dong)(dong)力電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。對于動(dong)(dong)力電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)而言(yan)，動(dong)(dong)力電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)性能指標，容量(liang)，使(shi)(shi)用(yong)壽(shou)命等，都是用(yong)來衡量(liang)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)性能指標之一，電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)在(zai)長期使(shi)(shi)用(yong)過程(cheng)當中，電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)容量(liang)等會(hui)隨著使(shi)(shi)用(yong)的(de)時間而降低，作(zuo)為電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)來說，循環(huan)次數(shu)和電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)有什么關(guan)(guan)系？

循環次(ci)數指的是(shi)(shi)電(dian)(dian)池在使用(yong)時候的時間和次(ci)數，換(huan)句話來(lai)說(shuo)(shuo)那么也就(jiu)是(shi)(shi)電(dian)(dian)池在充(chong)滿(man)以后，然后又把(ba)電(dian)(dian)池換(huan)光了，然后再(zai)充(chong)滿(man)，在放光，然后在充(chong)滿(man)反復(fu)循環。對于動(dong)力電(dian)(dian)池來(lai)說(shuo)(shuo)，一(yi)個(ge)完整充(chong)放電(dian)(dian)過(guo)程才是(shi)(shi)一(yi)個(ge)循環，根據這個(ge)東西(xi)來(lai)看(kan)，電(dian)(dian)池都是(shi)(shi)有(you)循環次(ci)數的。

根(gen)據三元鋰(li)電(dian)池(chi)的(de)使(shi)(shi)(shi)用(yong)壽命來說，電(dian)池(chi)的(de)使(shi)(shi)(shi)用(yong)壽命是(shi)在1500到(dao)2000次(ci)(ci)左(zuo)右的(de)循(xun)(xun)環(huan)(huan)次(ci)(ci)數(shu)，而(er)這一循(xun)(xun)環(huan)(huan)次(ci)(ci)數(shu)，會(hui)隨著(zhu)電(dian)池(chi)在使(shi)(shi)(shi)用(yong)過(guo)(guo)程(cheng)當中(zhong)出現變少的(de)情況，循(xun)(xun)環(huan)(huan)次(ci)(ci)數(shu)減(jian)(jian)少，意味著(zhu)電(dian)池(chi)的(de)使(shi)(shi)(shi)用(yong)壽命也是(shi)在不斷的(de)減(jian)(jian)少，在使(shi)(shi)(shi)用(yong)的(de)過(guo)(guo)程(cheng)中(zhong)，由于電(dian)池(chi)的(de)循(xun)(xun)環(huan)(huan)次(ci)(ci)數(shu)在不斷的(de)減(jian)(jian)少，那么也就意味著(zhu)鋰(li)電(dian)池(chi)內部會(hui)發生不可逆(ni)的(de)電(dian)化學(xue)反(fan)應導致容量下降。

總結：鋰電(dian)(dian)池(chi)(chi)生(sheng)命(ming)循環次數是根據電(dian)(dian)池(chi)(chi)質量和電(dian)(dian)池(chi)(chi)材料來定，鋰電(dian)(dian)池(chi)(chi)的(de)(de)循環次數和電(dian)(dian)池(chi)(chi)之間的(de)(de)使(shi)用壽命(ming)之類的(de)(de)是密不可(ke)分的(de)(de)聯(lian)系。每完成一個(ge)循環次數，對于(yu)(yu)電(dian)(dian)池(chi)(chi)的(de)(de)容量來說就會(hui)減少一點，相(xiang)對于(yu)(yu)電(dian)(dian)池(chi)(chi)的(de)(de)使(shi)用壽命(ming)也(ye)會(hui)減少。
