動力(li)電(dian)池(chi)(chi)(chi)(chi)(chi)作為純(chun)電(dian)動汽車的(de)(de)＂心臟(zang)＂，純(chun)電(dian)動汽車的(de)(de)關鍵在于動力(li)電(dian)池(chi)(chi)(chi)(chi)(chi)。對于動力(li)電(dian)池(chi)(chi)(chi)(chi)(chi)而(er)言，動力(li)電(dian)池(chi)(chi)(chi)(chi)(chi)性(xing)能指(zhi)標，容(rong)量，使用壽命等，都(dou)是(shi)用來衡量電(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)性(xing)能指(zhi)標之一，電(dian)池(chi)(chi)(chi)(chi)(chi)在長期使用過(guo)程(cheng)當中，電(dian)池(chi)(chi)(chi)(chi)(chi)容(rong)量等會隨著使用的(de)(de)時間而(er)降低，作為電(dian)池(chi)(chi)(chi)(chi)(chi)來說，循環(huan)次數(shu)和電(dian)池(chi)(chi)(chi)(chi)(chi)有什么關系？

循環(huan)(huan)次數指的是(shi)電(dian)(dian)池(chi)在使用時(shi)(shi)候的時(shi)(shi)間和次數，換(huan)句話來說那么(me)也就是(shi)電(dian)(dian)池(chi)在充(chong)(chong)(chong)滿以(yi)后(hou)，然(ran)(ran)后(hou)又把電(dian)(dian)池(chi)換(huan)光(guang)了，然(ran)(ran)后(hou)再(zai)充(chong)(chong)(chong)滿，在放光(guang)，然(ran)(ran)后(hou)在充(chong)(chong)(chong)滿反復循環(huan)(huan)。對于動力電(dian)(dian)池(chi)來說，一個(ge)完整充(chong)(chong)(chong)放電(dian)(dian)過程才是(shi)一個(ge)循環(huan)(huan)，根(gen)據這個(ge)東西來看(kan)，電(dian)(dian)池(chi)都是(shi)有(you)循環(huan)(huan)次數的。

根據三(san)元(yuan)鋰電(dian)池(chi)的使用(yong)壽命(ming)來說，電(dian)池(chi)的使用(yong)壽命(ming)是在1500到2000次(ci)(ci)左右的循環次(ci)(ci)數(shu)(shu)，而這一循環次(ci)(ci)數(shu)(shu)，會(hui)隨著電(dian)池(chi)在使用(yong)過程當中(zhong)出現變少的情況，循環次(ci)(ci)數(shu)(shu)減少，意(yi)味(wei)著電(dian)池(chi)的使用(yong)壽命(ming)也(ye)是在不斷的減少，在使用(yong)的過程中(zhong)，由(you)于電(dian)池(chi)的循環次(ci)(ci)數(shu)(shu)在不斷的減少，那么也(ye)就意(yi)味(wei)著鋰電(dian)池(chi)內部會(hui)發生不可逆(ni)的電(dian)化學反應(ying)導(dao)致容量下降。

總(zong)結(jie)：鋰電池(chi)(chi)(chi)(chi)生命(ming)循環次(ci)(ci)數(shu)是根據電池(chi)(chi)(chi)(chi)質(zhi)量(liang)和(he)電池(chi)(chi)(chi)(chi)材(cai)料來定，鋰電池(chi)(chi)(chi)(chi)的循環次(ci)(ci)數(shu)和(he)電池(chi)(chi)(chi)(chi)之間的使用(yong)壽命(ming)之類的是密不可分的聯系(xi)。每完成一(yi)個循環次(ci)(ci)數(shu)，對(dui)于(yu)電池(chi)(chi)(chi)(chi)的容量(liang)來說就會減少一(yi)點(dian)，相對(dui)于(yu)電池(chi)(chi)(chi)(chi)的使用(yong)壽命(ming)也會減少。
