動(dong)(dong)力電(dian)(dian)(dian)(dian)池(chi)作為純電(dian)(dian)(dian)(dian)動(dong)(dong)汽(qi)車的(de)(de)＂心臟＂，純電(dian)(dian)(dian)(dian)動(dong)(dong)汽(qi)車的(de)(de)關(guan)鍵在于動(dong)(dong)力電(dian)(dian)(dian)(dian)池(chi)。對于動(dong)(dong)力電(dian)(dian)(dian)(dian)池(chi)而言，動(dong)(dong)力電(dian)(dian)(dian)(dian)池(chi)性能指標，容(rong)量，使用(yong)(yong)壽命等，都是用(yong)(yong)來衡量電(dian)(dian)(dian)(dian)池(chi)的(de)(de)性能指標之一，電(dian)(dian)(dian)(dian)池(chi)在長期使用(yong)(yong)過程當中，電(dian)(dian)(dian)(dian)池(chi)容(rong)量等會隨著使用(yong)(yong)的(de)(de)時(shi)間而降低，作為電(dian)(dian)(dian)(dian)池(chi)來說，循環(huan)次數(shu)和電(dian)(dian)(dian)(dian)池(chi)有什么關(guan)系？

循(xun)環(huan)(huan)次數指的(de)是電(dian)(dian)(dian)池在(zai)使用時候的(de)時間和次數，換句(ju)話來說那么(me)也(ye)就是電(dian)(dian)(dian)池在(zai)充滿(man)(man)以后，然后又把電(dian)(dian)(dian)池換光了，然后再充滿(man)(man)，在(zai)放(fang)光，然后在(zai)充滿(man)(man)反復(fu)循(xun)環(huan)(huan)。對于動(dong)力電(dian)(dian)(dian)池來說，一個完整充放(fang)電(dian)(dian)(dian)過(guo)程才是一個循(xun)環(huan)(huan)，根據這個東西來看，電(dian)(dian)(dian)池都是有循(xun)環(huan)(huan)次數的(de)。

根據(ju)三(san)元(yuan)鋰(li)電池(chi)(chi)的(de)(de)(de)使(shi)(shi)用(yong)(yong)壽命來說，電池(chi)(chi)的(de)(de)(de)使(shi)(shi)用(yong)(yong)壽命是在1500到2000次(ci)左右的(de)(de)(de)循(xun)(xun)環(huan)次(ci)數(shu)，而(er)這一(yi)循(xun)(xun)環(huan)次(ci)數(shu)，會隨著電池(chi)(chi)在使(shi)(shi)用(yong)(yong)過(guo)程當中(zhong)出現(xian)變少(shao)(shao)的(de)(de)(de)情況，循(xun)(xun)環(huan)次(ci)數(shu)減(jian)(jian)少(shao)(shao)，意味著電池(chi)(chi)的(de)(de)(de)使(shi)(shi)用(yong)(yong)壽命也(ye)是在不斷的(de)(de)(de)減(jian)(jian)少(shao)(shao)，在使(shi)(shi)用(yong)(yong)的(de)(de)(de)過(guo)程中(zhong)，由(you)于電池(chi)(chi)的(de)(de)(de)循(xun)(xun)環(huan)次(ci)數(shu)在不斷的(de)(de)(de)減(jian)(jian)少(shao)(shao)，那么也(ye)就意味著鋰(li)電池(chi)(chi)內部會發生(sheng)不可逆的(de)(de)(de)電化(hua)學(xue)反(fan)應(ying)導致容(rong)量下降(jiang)。

總結(jie)：鋰(li)電池生命(ming)循環(huan)次(ci)數(shu)是根據電池質(zhi)量和(he)(he)電池材料來定，鋰(li)電池的(de)循環(huan)次(ci)數(shu)和(he)(he)電池之間(jian)的(de)使(shi)用壽命(ming)之類的(de)是密不可分的(de)聯系(xi)。每完成一個循環(huan)次(ci)數(shu)，對(dui)于(yu)電池的(de)容量來說(shuo)就會減少一點(dian)，相(xiang)對(dui)于(yu)電池的(de)使(shi)用壽命(ming)也會減少。
