動(dong)(dong)力電(dian)(dian)池(chi)(chi)作(zuo)為(wei)純電(dian)(dian)動(dong)(dong)汽車(che)的(de)(de)＂心臟＂，純電(dian)(dian)動(dong)(dong)汽車(che)的(de)(de)關鍵在于(yu)動(dong)(dong)力電(dian)(dian)池(chi)(chi)。對于(yu)動(dong)(dong)力電(dian)(dian)池(chi)(chi)而言，動(dong)(dong)力電(dian)(dian)池(chi)(chi)性能(neng)指標(biao)，容量，使(shi)(shi)用(yong)壽命等(deng)，都(dou)是用(yong)來衡量電(dian)(dian)池(chi)(chi)的(de)(de)性能(neng)指標(biao)之一，電(dian)(dian)池(chi)(chi)在長期使(shi)(shi)用(yong)過程當中，電(dian)(dian)池(chi)(chi)容量等(deng)會隨著使(shi)(shi)用(yong)的(de)(de)時間(jian)而降低，作(zuo)為(wei)電(dian)(dian)池(chi)(chi)來說，循環次數和電(dian)(dian)池(chi)(chi)有(you)什么關系？

循(xun)(xun)環(huan)次數(shu)指的(de)是(shi)(shi)(shi)電(dian)池(chi)在(zai)使用(yong)時候的(de)時間(jian)和(he)次數(shu)，換句話來說那么(me)也(ye)就是(shi)(shi)(shi)電(dian)池(chi)在(zai)充(chong)滿以后(hou)，然后(hou)又把電(dian)池(chi)換光了，然后(hou)再充(chong)滿，在(zai)放(fang)光，然后(hou)在(zai)充(chong)滿反復(fu)循(xun)(xun)環(huan)。對(dui)于(yu)動力電(dian)池(chi)來說，一個(ge)完整充(chong)放(fang)電(dian)過程(cheng)才是(shi)(shi)(shi)一個(ge)循(xun)(xun)環(huan)，根據這個(ge)東西來看，電(dian)池(chi)都是(shi)(shi)(shi)有循(xun)(xun)環(huan)次數(shu)的(de)。

根據三元(yuan)鋰電(dian)(dian)(dian)池(chi)的使(shi)(shi)用(yong)壽命來說，電(dian)(dian)(dian)池(chi)的使(shi)(shi)用(yong)壽命是在(zai)1500到(dao)2000次(ci)左右(you)的循(xun)環次(ci)數(shu)，而這一循(xun)環次(ci)數(shu)，會(hui)隨著(zhu)電(dian)(dian)(dian)池(chi)在(zai)使(shi)(shi)用(yong)過程(cheng)當中出現變(bian)少(shao)的情況，循(xun)環次(ci)數(shu)減少(shao)，意(yi)味(wei)著(zhu)電(dian)(dian)(dian)池(chi)的使(shi)(shi)用(yong)壽命也(ye)是在(zai)不斷的減少(shao)，在(zai)使(shi)(shi)用(yong)的過程(cheng)中，由于電(dian)(dian)(dian)池(chi)的循(xun)環次(ci)數(shu)在(zai)不斷的減少(shao)，那么也(ye)就(jiu)意(yi)味(wei)著(zhu)鋰電(dian)(dian)(dian)池(chi)內部會(hui)發生不可逆(ni)的電(dian)(dian)(dian)化學反應導致容量下降。

總結：鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)生命循(xun)環次(ci)數(shu)是(shi)根據電(dian)(dian)(dian)(dian)池(chi)(chi)質量和電(dian)(dian)(dian)(dian)池(chi)(chi)材料來定(ding)，鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)的循(xun)環次(ci)數(shu)和電(dian)(dian)(dian)(dian)池(chi)(chi)之間的使(shi)(shi)用壽命之類的是(shi)密不可分的聯(lian)系。每完成一個循(xun)環次(ci)數(shu)，對于電(dian)(dian)(dian)(dian)池(chi)(chi)的容量來說就(jiu)會(hui)減少一點(dian)，相對于電(dian)(dian)(dian)(dian)池(chi)(chi)的使(shi)(shi)用壽命也會(hui)減少。
