動力(li)電(dian)(dian)(dian)(dian)池(chi)(chi)作為(wei)(wei)純電(dian)(dian)(dian)(dian)動汽(qi)車的＂心臟＂，純電(dian)(dian)(dian)(dian)動汽(qi)車的關鍵在于動力(li)電(dian)(dian)(dian)(dian)池(chi)(chi)。對于動力(li)電(dian)(dian)(dian)(dian)池(chi)(chi)而(er)言，動力(li)電(dian)(dian)(dian)(dian)池(chi)(chi)性(xing)能(neng)指標(biao)，容量，使(shi)用壽命(ming)等，都是用來(lai)衡量電(dian)(dian)(dian)(dian)池(chi)(chi)的性(xing)能(neng)指標(biao)之一，電(dian)(dian)(dian)(dian)池(chi)(chi)在長期使(shi)用過程當中，電(dian)(dian)(dian)(dian)池(chi)(chi)容量等會(hui)隨著使(shi)用的時(shi)間而(er)降低，作為(wei)(wei)電(dian)(dian)(dian)(dian)池(chi)(chi)來(lai)說，循環(huan)次數(shu)和電(dian)(dian)(dian)(dian)池(chi)(chi)有什(shen)么關系？

循(xun)環(huan)次數指的是(shi)(shi)電池(chi)在(zai)使用時候的時間和次數，換句(ju)話來(lai)說那么(me)也(ye)就是(shi)(shi)電池(chi)在(zai)充(chong)(chong)滿以后(hou)，然后(hou)又(you)把電池(chi)換光了，然后(hou)再充(chong)(chong)滿，在(zai)放光，然后(hou)在(zai)充(chong)(chong)滿反(fan)復循(xun)環(huan)。對于動(dong)力電池(chi)來(lai)說，一個(ge)完整充(chong)(chong)放電過程才是(shi)(shi)一個(ge)循(xun)環(huan)，根(gen)據這(zhe)個(ge)東(dong)西來(lai)看，電池(chi)都(dou)是(shi)(shi)有循(xun)環(huan)次數的。

根據三(san)元鋰(li)電(dian)(dian)池的(de)(de)(de)使(shi)(shi)用(yong)(yong)壽(shou)命(ming)來說，電(dian)(dian)池的(de)(de)(de)使(shi)(shi)用(yong)(yong)壽(shou)命(ming)是在(zai)1500到2000次(ci)(ci)左右的(de)(de)(de)循環次(ci)(ci)數，而這一循環次(ci)(ci)數，會(hui)隨(sui)著電(dian)(dian)池在(zai)使(shi)(shi)用(yong)(yong)過程(cheng)當中出現(xian)變少(shao)的(de)(de)(de)情(qing)況，循環次(ci)(ci)數減少(shao)，意味著電(dian)(dian)池的(de)(de)(de)使(shi)(shi)用(yong)(yong)壽(shou)命(ming)也是在(zai)不(bu)(bu)斷(duan)的(de)(de)(de)減少(shao)，在(zai)使(shi)(shi)用(yong)(yong)的(de)(de)(de)過程(cheng)中，由(you)于電(dian)(dian)池的(de)(de)(de)循環次(ci)(ci)數在(zai)不(bu)(bu)斷(duan)的(de)(de)(de)減少(shao)，那么(me)也就意味著鋰(li)電(dian)(dian)池內(nei)部會(hui)發(fa)生不(bu)(bu)可(ke)逆的(de)(de)(de)電(dian)(dian)化學反應導致(zhi)容(rong)量下降。

總結：鋰電(dian)池(chi)(chi)生(sheng)命(ming)循環次(ci)數(shu)是根據(ju)電(dian)池(chi)(chi)質量和電(dian)池(chi)(chi)材料(liao)來定，鋰電(dian)池(chi)(chi)的(de)循環次(ci)數(shu)和電(dian)池(chi)(chi)之間(jian)的(de)使用壽命(ming)之類的(de)是密不可分的(de)聯系。每完成一個循環次(ci)數(shu)，對于(yu)電(dian)池(chi)(chi)的(de)容量來說就會(hui)減少一點，相對于(yu)電(dian)池(chi)(chi)的(de)使用壽命(ming)也(ye)會(hui)減少。
