對于很多不做鋰電池的盆友來說，鋰電池壽命有多長，其實并沒有什么很好的了解，就手機鋰電池壽命有多長，大家普遍的習慣是一般2年左右吧。其實這個也不能說不對，因為對于好的手機品牌，三兩年的使用壽命是沒什么問題的。但就目前來說，鋰電池行業比較認可的說法是循環使用500到600次這樣，再加上現在手機鋰電池容量一般都是比較高的，如果一天不是使用的很頻繁的話，一般也就用個50%左右的電，也就是說你每天手機用電是50%左右，一天充一次，基本上正常使用都是兩年以上了。

鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)循環使(shi)用(yong)壽命(ming)理論上是(shi)完(wan)全(quan)(quan)充放電(dian)(dian)(dian)(dian)500次左(zuo)右，相信(xin)絕大部(bu)分消費(fei)者都聽說過(guo)，超過(guo)這(zhe)個次數，電(dian)(dian)(dian)(dian)池(chi)(chi)就(jiu)(jiu)“壽終正(zheng)寢”了，其(qi)實(shi)這(zhe)個應該說電(dian)(dian)(dian)(dian)池(chi)(chi)會變得很(hen)不(bu)耐用(yong)，就(jiu)(jiu)是(shi)充電(dian)(dian)(dian)(dian)發熱嚴重，用(yong)又(you)(you)電(dian)(dian)(dian)(dian)發熱又(you)(you)耗(hao)電(dian)(dian)(dian)(dian)快。許多朋友就(jiu)(jiu)誤解了，誤以為為了能夠延長電(dian)(dian)(dian)(dian)池(chi)(chi)的壽命(ming)，每次都在(zai)電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)量完(wan)全(quan)(quan)耗(hao)盡時才(cai)進行(xing)充電(dian)(dian)(dian)(dian)，這(zhe)樣可以延長鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)的壽命(ming)真。

其實是(shi)(shi)理(li)解錯(cuo)了，鋰(li)電(dian)(dian)(dian)(dian)池(chi)的(de)壽(shou)(shou)命是(shi)(shi)“500次(ci)(ci)循(xun)環”，指的(de)不(bu)(bu)是(shi)(shi)充(chong)電(dian)(dian)(dian)(dian)的(de)次(ci)(ci)數，而(er)是(shi)(shi)一(yi)(yi)(yi)個(ge)充(chong)放電(dian)(dian)(dian)(dian)的(de)周(zhou)(zhou)(zhou)期(qi)(qi)(qi)，比如(ru)手機有60%的(de)電(dian)(dian)(dian)(dian)量(liang)(liang)，進行充(chong)電(dian)(dian)(dian)(dian)充(chong)滿100%，這樣要重(zhong)復2.5次(ci)(ci)之后，總(zong)共累計才是(shi)(shi)完(wan)成(cheng)一(yi)(yi)(yi)個(ge)充(chong)電(dian)(dian)(dian)(dian)周(zhou)(zhou)(zhou)期(qi)(qi)(qi)，之后是(shi)(shi)下一(yi)(yi)(yi)個(ge)周(zhou)(zhou)(zhou)期(qi)(qi)(qi)。一(yi)(yi)(yi)塊(kuai)(kuai)鋰(li)電(dian)(dian)(dian)(dian)在第(di)一(yi)(yi)(yi)天只(zhi)用(yong)(yong)了一(yi)(yi)(yi)半的(de)電(dian)(dian)(dian)(dian)量(liang)(liang)，然后又為它(ta)(ta)充(chong)滿電(dian)(dian)(dian)(dian)。如(ru)果第(di)二天還如(ru)此，即用(yong)(yong)一(yi)(yi)(yi)半就充(chong)，總(zong)共兩次(ci)(ci)充(chong)電(dian)(dian)(dian)(dian)下來(lai)，這只(zhi)能算作一(yi)(yi)(yi)個(ge)充(chong)電(dian)(dian)(dian)(dian)周(zhou)(zhou)(zhou)期(qi)(qi)(qi)，而(er)不(bu)(bu)是(shi)(shi)兩個(ge)。因(yin)此，通常可能要經過(guo)(guo)好幾次(ci)(ci)充(chong)電(dian)(dian)(dian)(dian)才完(wan)成(cheng)一(yi)(yi)(yi)個(ge)周(zhou)(zhou)(zhou)期(qi)(qi)(qi)。每完(wan)成(cheng)一(yi)(yi)(yi)個(ge)充(chong)電(dian)(dian)(dian)(dian)周(zhou)(zhou)(zhou)期(qi)(qi)(qi)，電(dian)(dian)(dian)(dian)量(liang)(liang)就會減(jian)少一(yi)(yi)(yi)點。不(bu)(bu)過(guo)(guo)，減(jian)少幅度非(fei)常小(xiao)，高品(pin)質的(de)電(dian)(dian)(dian)(dian)池(chi)充(chong)過(guo)(guo)多次(ci)(ci)周(zhou)(zhou)(zhou)期(qi)(qi)(qi)后，仍然會保留原(yuan)始(shi)電(dian)(dian)(dian)(dian)量(liang)(liang)的(de)80%。假設一(yi)(yi)(yi)次(ci)(ci)完(wan)全(quan)放電(dian)(dian)(dian)(dian)的(de)電(dian)(dian)(dian)(dian)量(liang)(liang)是(shi)(shi)Q，一(yi)(yi)(yi)塊(kuai)(kuai)電(dian)(dian)(dian)(dian)池(chi)的(de)周(zhou)(zhou)(zhou)期(qi)(qi)(qi)為500次(ci)(ci)，那么它(ta)(ta)在壽(shou)(shou)命中提供的(de)總(zong)電(dian)(dian)(dian)(dian)量(liang)(liang)是(shi)(shi)500Q，如(ru)果我(wo)們將電(dian)(dian)(dian)(dian)量(liang)(liang)用(yong)(yong)到一(yi)(yi)(yi)半時充(chong)電(dian)(dian)(dian)(dian)，設充(chong)電(dian)(dian)(dian)(dian)次(ci)(ci)數為A，簡(jian)單地求解，1/2Q*A=500Q，A應該是(shi)(shi)1000次(ci)(ci)。因(yin)此對于電(dian)(dian)(dian)(dian)池(chi)壽(shou)(shou)命，我(wo)們可以用(yong)(yong)周(zhou)(zhou)(zhou)期(qi)(qi)(qi)來(lai)衡量(liang)(liang)，但是(shi)(shi)絕不(bu)(bu)要用(yong)(yong)次(ci)(ci)數來(lai)衡量(liang)(liang)。

對(dui)于(yu)(yu)鋰電(dian)(dian)池性(xing)能(neng)在(zai)100次使用(yong)之后，達到(dao)一(yi)(yi)(yi)個(ge)峰(feng)值的(de)說法是錯誤的(de)，對(dui)于(yu)(yu)鋰離子電(dian)(dian)池，根本不存在(zai)這(zhe)樣(yang)一(yi)(yi)(yi)個(ge)循(xun)環容(rong)量的(de)駝(tuo)峰(feng)現(xian)象(xiang)，從鋰離子電(dian)(dian)池出廠到(dao)最終報(bao)廢(fei)，其(qi)容(rong)量的(de)表現(xian)就(jiu)是用(yong)一(yi)(yi)(yi)次少一(yi)(yi)(yi)次，循(xun)環時不會出現(xian)性(xing)能(neng)回升的(de)現(xian)象(xiang)。

還有就認為應該將手機(ji)電(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)盡(jin)(jin)可能用(yong)光再充電(dian)(dian)(dian)，這種(zhong)說法(fa)是(shi)錯誤的(de)！其實過(guo)多的(de)對鋰(li)電(dian)(dian)(dian)池(chi)(chi)深度放電(dian)(dian)(dian)反而是(shi)對電(dian)(dian)(dian)池(chi)(chi)最(zui)大的(de)傷害，會造成材(cai)料析鋰(li)，電(dian)(dian)(dian)池(chi)(chi)提前進(jin)入老化而報廢，因此我(wo)們使用(yong)手機(ji)鋰(li)電(dian)(dian)(dian)池(chi)(chi)的(de)時候(hou)盡(jin)(jin)量按下面(mian)的(de)方法(fa)去做：

1.不必刻意保(bao)證每一(yi)次都放完電了再(zai)充(chong)；

2.一(yi)段(duan)時間可做一(yi)次保護電(dian)(dian)路(lu)控制下(xia)的深充放以修(xiu)正電(dian)(dian)池的電(dian)(dian)量(liang)統計，但這不(bu)會提高你電(dian)(dian)池的實(shi)際容

3.長期(qi)不用的電(dian)池，應(ying)放在陰涼的地方(fang)以減(jian)弱其內部自身鈍化反應(ying)的速(su)度。

4.保護(hu)電(dian)(dian)路也無力監(jian)控電(dian)(dian)池的自(zi)放電(dian)(dian)，長期(qi)不用(yong)的電(dian)(dian)池，應充入一定的電(dian)(dian)量以(yi)防電(dian)(dian)池在存(cun)貯中自(zi)放電(dian)(dian)過量導(dao)致過度放電(dian)(dian)的損壞(huai)。
