聚合物鋰電池充電方法

目前鋰充(chong)(chong)(chong)電(dian)(dian)主(zhu)要是(shi)限壓限流法，初期(qi)恒(heng)(heng)流(CC)充(chong)(chong)(chong)電(dian)(dian)，電(dian)(dian)池接受能(neng)力最(zui)強(qiang)，隨著充(chong)(chong)(chong)電(dian)(dian)過程不(bu)斷(duan)進行(xing)，極(ji)化作用(yong)加(jia)強(qiang)，溫(wen)升(sheng)加(jia)劇，電(dian)(dian)壓上升(sheng)，當荷(he)電(dian)(dian)達到約(yue)70~80%時，電(dian)(dian)壓達到最(zui)高充(chong)(chong)(chong)電(dian)(dian)限制電(dian)(dian)壓，轉入(ru)恒(heng)(heng)壓(CV)充(chong)(chong)(chong)電(dian)(dian)階段(duan)。在恒(heng)(heng)壓階段(duan)，有稱涓流充(chong)(chong)(chong)電(dian)(dian)，大約(yue)花費30%的(de)(de)時間(jian)充(chong)(chong)(chong)入(ru)10%的(de)(de)電(dian)(dian)量，電(dian)(dian)流強(qiang)度減小，溫(wen)升(sheng)不(bu)再增加(jia)。

這種(zhong)過(guo)(guo)程考慮電池(chi)組總電壓或(huo)平(ping)均(jun)電壓控制，其實總有單體(ti)電壓較(jiao)高者，相對(dui)組內其它電池(chi)已(yi)經進入過(guo)(guo)充(chong)電階(jie)段。同(tong)理，在(zai)放(fang)電時，在(zai)組內就有過(guo)(guo)放(fang)電電池(chi)，過(guo)(guo)充(chong)過(guo)(guo)放(fang)對(dui)電池(chi)的損害都是(shi)致命的，不同(tong)之處僅在(zai)于過(guo)(guo)充(chong)產生大量氣體(ti)、易(yi)自燃和爆炸(zha)、表象劇烈(lie)；過(guo)(guo)放(fang)外觀變化和緩、但失效速度卻極快，在(zai)正常使用中都應嚴格避免(mian)出現。

對(dui)此,就有一(yi)(yi)種(zhong)(zhong)稱為并聯控(kong)制、均(jun)(jun)衡(heng)(heng)管理的(de)(de)新的(de)(de)鋰電(dian)(dian)充(chong)電(dian)(dian)方法，能夠對(dui)每一(yi)(yi)節電(dian)(dian)蕊單(dan)獨進(jin)行充(chong)放(fang)電(dian)(dian)管理，均(jun)(jun)衡(heng)(heng)控(kong)制，這種(zhong)(zhong)動態均(jun)(jun)衡(heng)(heng)集中了放(fang)電(dian)(dian)均(jun)(jun)衡(heng)(heng)與充(chong)電(dian)(dian)均(jun)(jun)衡(heng)(heng)兩種(zhong)(zhong)均(jun)(jun)衡(heng)(heng)的(de)(de)優點(dian)，盡管單(dan)體電(dian)(dian)蕊之間初始(shi)容(rong)量、電(dian)(dian)壓、內阻等有差異，在(zai)工作中卻能保證相對(dui)的(de)(de)充(chong)放(fang)電(dian)(dian)強度和(he)深度的(de)(de)一(yi)(yi)致性，漸進(jin)達到共同的(de)(de)壽命終點(dian)。這種(zhong)(zhong)方法對(dui)大電(dian)(dian)流放(fang)電(dian)(dian)特別適用。

因此(ci)，在給鋰(li)電(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)時，一(yi)定要(yao)使(shi)用(yong)(yong)(yong)專用(yong)(yong)(yong)的鋰(li)電(dian)(dian)充(chong)(chong)電(dian)(dian)器，特別是要(yao)注意與所使(shi)用(yong)(yong)(yong)的電(dian)(dian)蕊(rui)的參數(shu)要(yao)配套，要(yao)一(yi)致，當(dang)鋰(li)電(dian)(dian)池(chi)組(zu)合使(shi)用(yong)(yong)(yong)時，一(yi)定要(yao)給電(dian)(dian)池(chi)組(zu)加PCB保護板(ban)，才(cai)可(ke)能避免電(dian)(dian)芯豉(chi)包、漏液、甚至起火、爆(bao)炸，盡可(ke)能的延長(chang)電(dian)(dian)池(chi)的使(shi)用(yong)(yong)(yong)壽命，不過充(chong)(chong)不過放(fang)，增加電(dian)(dian)池(chi)的循環(huan)使(shi)用(yong)(yong)(yong)次數(shu)。

鋰聚合物電池保養方法

作為(wei)鋰離子(zi)電池(chi)之后(hou)進行革(ge)新得到的新電池(chi)產品，鋰聚合(he)物(wu)電池(chi)在(zai)使用中(zhong)有一(yi)些需要注(zhu)意的地方。

首先，是(shi)鋰(li)聚(ju)(ju)合(he)物電(dian)(dian)(dian)(dian)池(chi)的特點。相比較鋰(li)離子電(dian)(dian)(dian)(dian)池(chi)，鋰(li)聚(ju)(ju)合(he)物電(dian)(dian)(dian)(dian)池(chi)改(gai)善(shan)了電(dian)(dian)(dian)(dian)池(chi)漏(lou)液的問(wen)題，但也并(bing)沒有徹底的改(gai)善(shan)。此外鋰(li)聚(ju)(ju)合(he)物電(dian)(dian)(dian)(dian)池(chi)能(neng)夠制作(zuo)成(cheng)超(chao)薄型電(dian)(dian)(dian)(dian)池(chi)，0.5mm的厚(hou)度(du)就可以達到3.6V400毫安時的容量，而(er)且在放(fang)電(dian)(dian)(dian)(dian)量上，鋰(li)聚(ju)(ju)合(he)物電(dian)(dian)(dian)(dian)池(chi)也比傳統(tong)鋰(li)離子電(dian)(dian)(dian)(dian)池(chi)高出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)充電(dian)的(de)時候，電(dian)池(chi)的(de)內部就會不斷的(de)升(sheng)溫(wen)，當溫(wen)度過高的(de)時候，就有(you)可能產生爆炸。

因此(ci)，當使用電池(chi)的時候，盡(jin)量(liang)注意不要(yao)過(guo)充(chong)(chong)過(guo)放，也就是平穩有計劃(hua)的使用電池(chi)，不要(yao)輕易讓電池(chi)電量(liang)耗(hao)盡(jin)，也不要(yao)充(chong)(chong)電的時候連(lian)續充(chong)(chong)太長的時間(jian)（一(yi)般來(lai)說8個(ge)小(xiao)時以內是最(zui)合適的）。
