聚合物鋰電池充電方法

目(mu)前鋰充電(dian)(dian)(dian)(dian)主(zhu)要(yao)是限(xian)(xian)壓(ya)限(xian)(xian)流法，初期恒(heng)流(CC)充電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)池(chi)接(jie)受能力最強，隨著充電(dian)(dian)(dian)(dian)過(guo)程(cheng)不斷進行，極化作用加(jia)強，溫升(sheng)加(jia)劇，電(dian)(dian)(dian)(dian)壓(ya)上升(sheng)，當荷(he)電(dian)(dian)(dian)(dian)達到(dao)約70~80%時(shi)，電(dian)(dian)(dian)(dian)壓(ya)達到(dao)最高充電(dian)(dian)(dian)(dian)限(xian)(xian)制電(dian)(dian)(dian)(dian)壓(ya)，轉入恒(heng)壓(ya)(CV)充電(dian)(dian)(dian)(dian)階段。在(zai)恒(heng)壓(ya)階段，有稱(cheng)涓流充電(dian)(dian)(dian)(dian)，大約花費30%的(de)(de)時(shi)間充入10%的(de)(de)電(dian)(dian)(dian)(dian)量，電(dian)(dian)(dian)(dian)流強度減小，溫升(sheng)不再(zai)增加(jia)。

這種過程考慮電(dian)(dian)池(chi)組總(zong)電(dian)(dian)壓(ya)或平均電(dian)(dian)壓(ya)控制(zhi)，其實總(zong)有單體(ti)電(dian)(dian)壓(ya)較高者，相對(dui)(dui)組內其它電(dian)(dian)池(chi)已(yi)經進入過充電(dian)(dian)階段。同理，在放(fang)電(dian)(dian)時(shi)，在組內就有過放(fang)電(dian)(dian)電(dian)(dian)池(chi)，過充過放(fang)對(dui)(dui)電(dian)(dian)池(chi)的(de)損害都是致命的(de)，不同之(zhi)處僅在于過充產生大量氣體(ti)、易自燃和(he)爆炸、表象(xiang)劇烈(lie)；過放(fang)外觀變化和(he)緩、但失效(xiao)速度卻(que)極快，在正常使用中(zhong)都應嚴格避(bi)免出現。

對此,就有(you)一種(zhong)稱為并聯控(kong)制(zhi)、均(jun)衡(heng)(heng)管理的新的鋰電(dian)充(chong)電(dian)方(fang)法，能(neng)夠對每一節電(dian)蕊單獨進行(xing)充(chong)放電(dian)管理，均(jun)衡(heng)(heng)控(kong)制(zhi)，這種(zhong)動態均(jun)衡(heng)(heng)集中了放電(dian)均(jun)衡(heng)(heng)與充(chong)電(dian)均(jun)衡(heng)(heng)兩種(zhong)均(jun)衡(heng)(heng)的優點(dian)，盡管單體電(dian)蕊之間初始容量、電(dian)壓、內阻等有(you)差異，在工作中卻(que)能(neng)保(bao)證相對的充(chong)放電(dian)強度(du)和深度(du)的一致性，漸進達(da)到共同的壽命終點(dian)。這種(zhong)方(fang)法對大電(dian)流放電(dian)特別適用(yong)。

因此，在給鋰(li)電(dian)池充電(dian)時，一定要(yao)使(shi)用專用的(de)鋰(li)電(dian)充電(dian)器，特(te)別是要(yao)注意與所使(shi)用的(de)電(dian)蕊的(de)參數(shu)要(yao)配套，要(yao)一致，當鋰(li)電(dian)池組(zu)合使(shi)用時，一定要(yao)給電(dian)池組(zu)加PCB保(bao)護板，才可能避免電(dian)芯豉(chi)包(bao)、漏(lou)液、甚至起火、爆炸，盡可能的(de)延長(chang)電(dian)池的(de)使(shi)用壽(shou)命，不(bu)(bu)過(guo)充不(bu)(bu)過(guo)放，增加電(dian)池的(de)循環(huan)使(shi)用次數(shu)。

鋰聚合物電池保養方法

作(zuo)為鋰(li)離子電池之后進(jin)行革新得到的新電池產品，鋰(li)聚合物電池在使用中有一些需(xu)要注意的地(di)方。

首先(xian)，是鋰(li)(li)(li)(li)(li)聚(ju)(ju)合(he)物電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)特點。相比(bi)較(jiao)鋰(li)(li)(li)(li)(li)離子電(dian)(dian)(dian)池(chi)(chi)(chi)，鋰(li)(li)(li)(li)(li)聚(ju)(ju)合(he)物電(dian)(dian)(dian)池(chi)(chi)(chi)改(gai)善(shan)了電(dian)(dian)(dian)池(chi)(chi)(chi)漏液的(de)問(wen)題(ti)，但也并沒有徹(che)底的(de)改(gai)善(shan)。此外鋰(li)(li)(li)(li)(li)聚(ju)(ju)合(he)物電(dian)(dian)(dian)池(chi)(chi)(chi)能夠制作(zuo)成超薄型電(dian)(dian)(dian)池(chi)(chi)(chi)，0.5mm的(de)厚度就可以達到(dao)3.6V400毫安(an)時的(de)容量，而且(qie)在放(fang)電(dian)(dian)(dian)量上(shang)，鋰(li)(li)(li)(li)(li)聚(ju)(ju)合(he)物電(dian)(dian)(dian)池(chi)(chi)(chi)也比(bi)傳(chuan)統鋰(li)(li)(li)(li)(li)離子電(dian)(dian)(dian)池(chi)(chi)(chi)高出(chu)10%。

而在日常使用中，同樣作為鋰離子電池的一種，鋰聚合物電池也常害怕電池內部的短、外部短、過充這些情況的。原因是因為鋰的化學性質非常的活躍，當電池放電(dian)(dian)充(chong)電(dian)(dian)的時候，電(dian)(dian)池的內部就會不斷(duan)的升溫，當溫度(du)過高的時候，就有(you)可(ke)能產生(sheng)爆炸(zha)。

因此(ci)，當使(shi)用電(dian)(dian)池(chi)的(de)時(shi)(shi)(shi)候(hou)，盡量注意不要過充過放，也就是平穩有(you)計劃的(de)使(shi)用電(dian)(dian)池(chi)，不要輕易讓電(dian)(dian)池(chi)電(dian)(dian)量耗盡，也不要充電(dian)(dian)的(de)時(shi)(shi)(shi)候(hou)連續充太長的(de)時(shi)(shi)(shi)間（一般來(lai)說8個小時(shi)(shi)(shi)以(yi)內是最合適(shi)的(de)）。
