聚合物鋰電池充電方法

目前鋰充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)主要是限(xian)壓限(xian)流法，初期(qi)恒流(CC)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池接受能力最強，隨著(zhu)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)過(guo)程不斷進行(xing)，極化作用加(jia)強，溫升(sheng)加(jia)劇(ju)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓上升(sheng)，當荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)達到約(yue)70~80%時，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓達到最高充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)限(xian)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，轉入恒壓(CV)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)階段。在恒壓階段，有稱涓流充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，大約(yue)花費30%的(de)時間充入10%的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流強度(du)減小，溫升(sheng)不再增加(jia)。

這(zhe)種過(guo)(guo)程考慮電(dian)(dian)池組(zu)總電(dian)(dian)壓(ya)或平均電(dian)(dian)壓(ya)控制，其實總有(you)單(dan)體電(dian)(dian)壓(ya)較高者，相(xiang)對(dui)組(zu)內其它(ta)電(dian)(dian)池已(yi)經進入過(guo)(guo)充電(dian)(dian)階段。同理，在(zai)放電(dian)(dian)時，在(zai)組(zu)內就有(you)過(guo)(guo)放電(dian)(dian)電(dian)(dian)池，過(guo)(guo)充過(guo)(guo)放對(dui)電(dian)(dian)池的損害都是致命的，不同之處僅在(zai)于過(guo)(guo)充產生大量氣體、易自(zi)燃(ran)和爆(bao)炸、表象(xiang)劇烈；過(guo)(guo)放外觀變(bian)化和緩、但失效速度卻極快(kuai)，在(zai)正常使用中(zhong)都應嚴格避免出現。

對(dui)此,就有(you)一(yi)種稱(cheng)為并聯控(kong)制、均(jun)(jun)衡管(guan)(guan)理的新的鋰(li)電(dian)充(chong)電(dian)方(fang)法(fa)，能夠對(dui)每一(yi)節電(dian)蕊(rui)單(dan)獨進(jin)行(xing)充(chong)放(fang)(fang)電(dian)管(guan)(guan)理，均(jun)(jun)衡控(kong)制，這(zhe)種動態均(jun)(jun)衡集中了放(fang)(fang)電(dian)均(jun)(jun)衡與充(chong)電(dian)均(jun)(jun)衡兩(liang)種均(jun)(jun)衡的優點，盡管(guan)(guan)單(dan)體電(dian)蕊(rui)之間初始容量(liang)、電(dian)壓、內阻等有(you)差異，在工作(zuo)中卻能保證相對(dui)的充(chong)放(fang)(fang)電(dian)強度和深度的一(yi)致(zhi)性，漸進(jin)達到共(gong)同(tong)的壽命終(zhong)點。這(zhe)種方(fang)法(fa)對(dui)大電(dian)流放(fang)(fang)電(dian)特別適(shi)用。

因(yin)此(ci)，在(zai)給鋰電(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)時，一定要(yao)使(shi)用(yong)專用(yong)的(de)鋰電(dian)(dian)(dian)(dian)充電(dian)(dian)(dian)(dian)器，特別是要(yao)注意(yi)與(yu)所(suo)使(shi)用(yong)的(de)電(dian)(dian)(dian)(dian)蕊的(de)參數要(yao)配(pei)套，要(yao)一致，當(dang)鋰電(dian)(dian)(dian)(dian)池(chi)(chi)組合使(shi)用(yong)時，一定要(yao)給電(dian)(dian)(dian)(dian)池(chi)(chi)組加PCB保護板，才(cai)可能(neng)避免電(dian)(dian)(dian)(dian)芯(xin)豉包、漏液、甚至(zhi)起火、爆炸，盡可能(neng)的(de)延長電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)使(shi)用(yong)壽命，不過(guo)(guo)充不過(guo)(guo)放(fang)，增加電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)循環使(shi)用(yong)次數。

鋰聚合物電(dian)池保養方法

作為(wei)鋰(li)離子電池之(zhi)后進行革新得(de)到(dao)的(de)(de)新電池產品，鋰(li)聚(ju)合(he)物電池在使用(yong)中有一些需要注意的(de)(de)地(di)方。

首先，是鋰(li)聚合物(wu)電(dian)池(chi)的特點。相(xiang)比較(jiao)鋰(li)離(li)子(zi)(zi)電(dian)池(chi)，鋰(li)聚合物(wu)電(dian)池(chi)改(gai)善了(le)電(dian)池(chi)漏液的問題，但也并(bing)沒有徹底的改(gai)善。此外鋰(li)聚合物(wu)電(dian)池(chi)能夠(gou)制作成超薄型電(dian)池(chi)，0.5mm的厚度就可以達到3.6V400毫(hao)安時的容量，而(er)且在放電(dian)量上(shang)，鋰(li)聚合物(wu)電(dian)池(chi)也比傳統鋰(li)離(li)子(zi)(zi)電(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，當電池放電充(chong)電的時候，電池的內部就會不斷的升溫，當溫度過(guo)高的時候，就有可能(neng)產生(sheng)爆炸(zha)。

因此，當使(shi)用(yong)電(dian)池的(de)(de)時(shi)候，盡量注意不要過(guo)(guo)充過(guo)(guo)放，也就是平穩有計劃(hua)的(de)(de)使(shi)用(yong)電(dian)池，不要輕(qing)易(yi)讓電(dian)池電(dian)量耗盡，也不要充電(dian)的(de)(de)時(shi)候連續充太長的(de)(de)時(shi)間（一般來說8個小(xiao)時(shi)以內是最合適的(de)(de)）。
