目前聚合物鋰離子電池充電主要是限壓限流法，初期恒流(CC)充電，電池接受能力最強，隨著充電過程不斷進行，極化作用加強，溫升加劇，電壓上升，當荷電達到約70~80%時，電壓達到最高充電限制電壓，轉入恒壓(CV)充電階段。在恒壓階段，有稱涓流充電，大約花費30%的時間充入10%的電量，電流強度減小，溫升不再增加。

這(zhe)種過程(cheng)考慮(lv)電(dian)(dian)池組總電(dian)(dian)壓或平均電(dian)(dian)壓控制，其實總有單體電(dian)(dian)壓較高(gao)者，相對組內其它(ta)電(dian)(dian)池已經進入過充電(dian)(dian)階段。同理(li)，在(zai)(zai)放(fang)電(dian)(dian)時(shi)，在(zai)(zai)組內就有過放(fang)電(dian)(dian)電(dian)(dian)池，過充過放(fang)對電(dian)(dian)池的損害都是致命的，不同之(zhi)處僅在(zai)(zai)于過充產生(sheng)大量(liang)氣(qi)體、易自燃和(he)爆炸、表象劇烈;過放(fang)外觀變化和(he)緩、但失效速度卻極(ji)快(kuai)，在(zai)(zai)正常使(shi)用中都應嚴格避(bi)免出現。

對此,就(jiu)有一(yi)種(zhong)稱為并聯控制、均衡(heng)(heng)(heng)管理的(de)新的(de)鋰電(dian)(dian)(dian)(dian)(dian)(dian)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)方法，能夠對每一(yi)節(jie)電(dian)(dian)(dian)(dian)(dian)(dian)蕊單獨進(jin)行(xing)充(chong)放電(dian)(dian)(dian)(dian)(dian)(dian)管理，均衡(heng)(heng)(heng)控制，這(zhe)種(zhong)動態均衡(heng)(heng)(heng)集(ji)中了(le)放電(dian)(dian)(dian)(dian)(dian)(dian)均衡(heng)(heng)(heng)與充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)均衡(heng)(heng)(heng)兩種(zhong)均衡(heng)(heng)(heng)的(de)優點，盡管單體電(dian)(dian)(dian)(dian)(dian)(dian)蕊之間初始容(rong)量、電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)、內(nei)阻等有差異(yi)，在工(gong)作中卻能保(bao)證相對的(de)充(chong)放電(dian)(dian)(dian)(dian)(dian)(dian)強(qiang)度(du)和深(shen)度(du)的(de)一(yi)致(zhi)性(xing)，漸(jian)進(jin)達(da)到共同的(de)壽命(ming)終點。這(zhe)種(zhong)方法對大電(dian)(dian)(dian)(dian)(dian)(dian)流放電(dian)(dian)(dian)(dian)(dian)(dian)特別適用，我公司(si)現已研制出對多(duo)達(da)20節(jie)的(de)串聯鋰電(dian)(dian)(dian)(dian)(dian)(dian)進(jin)行(xing)PCB均衡(heng)(heng)(heng)保(bao)護(hu)，最高放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流可達(da)100A。

因(yin)此，在給鋰電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)時，一定要使用(yong)專(zhuan)用(yong)的(de)(de)鋰電(dian)(dian)(dian)(dian)充(chong)電(dian)(dian)(dian)(dian)器，特(te)別是要注意與所使用(yong)的(de)(de)電(dian)(dian)(dian)(dian)蕊(rui)(rui)的(de)(de)參數要配套，要一致(zhi)，當鋰電(dian)(dian)(dian)(dian)池(chi)組(zu)合使用(yong)時，一定要給電(dian)(dian)(dian)(dian)池(chi)組(zu)加PCB保護板，才可(ke)能避免電(dian)(dian)(dian)(dian)蕊(rui)(rui)豉包、漏液(ye)、甚至起(qi)火(huo)、爆炸，盡可(ke)能長地(di)延長電(dian)(dian)(dian)(dian)池(chi)的(de)(de)使用(yong)壽命，不(bu)(bu)過充(chong)不(bu)(bu)過放，增加電(dian)(dian)(dian)(dian)池(chi)的(de)(de)循環使用(yong)次數。

聚合物(wu)鋰離(li)子電池激活

關于聚(ju)合(he)物鋰(li)(li)離(li)子(zi)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是否激活(huo)的(de)問題一直都存在爭(zheng)議。有部分(fen)網友覺得(de)一般鋰(li)(li)離(li)子(zi)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)不用激活(huo)，假設電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)擱置時(shi)間太久了(le)，可以(yi)在充(chong)完(wan)電(dian)(dian)(dian)(dian)后(hou)再充(chong)幾(ji)個小(xiao)(xiao)時(shi)。超過(guo)12小(xiao)(xiao)時(shi)就不行了(le)。大(da)家知(zhi)道的(de)常識說(shuo)前三次充(chong)12小(xiao)(xiao)時(shi)那個說(shuo)法是對原(yuan)來的(de)鎳(nie)鎘(ge)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)而言。鋰(li)(li)離(li)子(zi)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)并不是，因為鋰(li)(li)離(li)子(zi)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)沒有記(ji)憶效應。專家說(shuo)過(guo)：一般化成(cheng)過(guo)程中需要(yao)一段時(shi)間的(de)小(xiao)(xiao)電(dian)(dian)(dian)(dian)流充(chong)放，為了(le)電(dian)(dian)(dian)(dian)極表面SEI膜(mo)的(de)形(xing)成(cheng)，這(zhe)(zhe)個當然是普(pu)通用戶的(de)充(chong)電(dian)(dian)(dian)(dian)器無法完(wan)成(cheng)的(de)，如(ru)果真的(de)有激活(huo)這(zhe)(zhe)種(zhong)說(shuo)法，那么(me)這(zhe)(zhe)么(me)重(zhong)要(yao)的(de)過(guo)程，生產商(shang)怎(zen)么(me)可能(neng)交給用戶自己完(wan)成(cheng)呢?

于(yu)是(shi)乎(hu)又(you)有用(yong)戶反映：跟據實踐(jian)經驗，鋰(li)(li)電池(chi)需要激(ji)(ji)(ji)活，因(yin)為(wei)記憶效應(ying)不(bu)(bu)可恢復(fu)，但如果鋰(li)(li)電池(chi)沒(mei)有激(ji)(ji)(ji)活的(de)(de)(de)話會導致(zhi)的(de)(de)(de)容(rong)(rong)量不(bu)(bu)足問題還可以(yi)恢復(fu)的(de)(de)(de)。不(bu)(bu)論什么數碼設備(bei)標配的(de)(de)(de)鋰(li)(li)電池(chi)，在(zai)啟用(yong)時(shi)都必(bi)須激(ji)(ji)(ji)活。很多用(yong)戶在(zai)使用(yong)鋰(li)(li)電池(chi)的(de)(de)(de)過(guo)程(cheng)時(shi)，沒(mei)有科學地(di)激(ji)(ji)(ji)活，導致(zhi)鋰(li)(li)電池(chi)不(bu)(bu)能達(da)到最佳(jia)容(rong)(rong)量，容(rong)(rong)易讓人錯以(yi)為(wei)這是(shi)記憶效應(ying)。

一般(ban)電池有如下激活過程：

激活過程一：剛(gang)使(shi)用的(de)(de)鋰電(dian)(dian)一般都有剩余的(de)(de)電(dian)(dian)量，這時(shi)候就不要(yao)充電(dian)(dian)。把(ba)電(dian)(dian)池裝(zhuang)進產品正常使(shi)用，直到電(dian)(dian)量低至完全無法開機。

激活過程二：第(di)一(yi)次充(chong)電(dian)，最(zui)好使用(yong)原配的(de)充(chong)電(dian)器充(chong)電(dian)，而且關(guan)機充(chong)比較好，很多人為了方便使用(yong)，不(bu)關(guan)機充(chong)電(dian)，這樣不(bu)利于激活鋰電(dian)容(rong)量。并且提(ti)醒(xing)大(da)家(jia)的(de)是要連續充(chong)電(dian)12小時(shi)以上15小時(shi)以下(xia)。期間若(ruo)提(ti)示已經充(chong)滿，不(bu)要理拔掉，讓(rang)它一(yi)直保持充(chong)電(dian)狀態!

激活過(guo)程三(san)：首次(ci)充滿電之(zhi)后(hou)，如果正(zheng)常使用至無法開(kai)機。可以再按按過(guo)程二繼續(xu)操作!

激(ji)活(huo)過程四：完全放電(dian)，完全充電(dian)(即重復過程二和過程三)反復三次。這時(shi)電(dian)池被激(ji)活(huo)成功(gong)，能達到最好的容量狀態。

注(zhu)意事項有(you)：鋰電(dian)(dian)(dian)池常(chang)常(chang)在(zai)出廠(chang)時就已(yi)經進行激(ji)活(huo)，所以不需要(yao)買家(jia)再(zai)次進行激(ji)活(huo)。如果激(ji)活(huo)期(qi)建(jian)議(yi)不要(yao)用(yong)(yong)萬(wan)能充電(dian)(dian)(dian)器(qi)。如果達到正常(chang)使用(yong)(yong)期(qi)后(hou)，能不用(yong)(yong)用(yong)(yong)萬(wan)能充電(dian)(dian)(dian)器(qi)就不用(yong)(yong)。因為原配的(de)充電(dian)(dian)(dian)器(qi)是最合(he)適的(de)。萬(wan)能充電(dian)(dian)(dian)器(qi)，電(dian)(dian)(dian)流不的(de)穩(wen)定性，與鋰電(dian)(dian)(dian)池電(dian)(dian)(dian)壓并不一定相符，有(you)加速鋰電(dian)(dian)(dian)老化的(de)可能。

聚合物鋰離子電(dian)池可分(fen)為(wei)三類：

（1）固體(ti)聚(ju)合物(wu)電(dian)(dian)解質鋰離子(zi)(zi)電(dian)(dian)池。電(dian)(dian)解質為聚(ju)合物(wu)與鹽的(de)混合物(wu)，這種電(dian)(dian)池在(zai)常溫下的(de)離子(zi)(zi)電(dian)(dian)導率低，適于高溫使用。

（2）凝膠聚(ju)合(he)物電(dian)(dian)解(jie)質鋰(li)離子電(dian)(dian)池。即在固體聚(ju)合(he)物電(dian)(dian)解(jie)質中加入增塑劑(ji)等添加劑(ji)，從而(er)提高離子電(dian)(dian)導率，使電(dian)(dian)池可在常溫下使用。

（3）聚(ju)合物正極材料(liao)的(de)鋰離(li)子電(dian)池。采用導(dao)電(dian)聚(ju)合物作為(wei)正極材料(liao)，其比能(neng)量是現有鋰離(li)子電(dian)池的(de)3倍，是最新一代的(de)鋰離(li)子電(dian)池。

新一代(dai)的(de)(de)聚合(he)物(wu)鋰離子(zi)電池(chi)(chi)在聚合(he)物(wu)化的(de)(de)程度上(shang)已經很高(gao)，所以(yi)(yi)形狀上(shang)可(ke)做到薄形化（最薄0.5毫米）、任意(yi)面積化和任意(yi)形狀化，大大提高(gao)了電池(chi)(chi)造型(xing)設計的(de)(de)靈活性(xing)(xing)，從而可(ke)以(yi)(yi)配合(he)產品需求，做成任何形狀與容量的(de)(de)電池(chi)(chi)。同時(shi)，聚合(he)物(wu)鋰離子(zi)電池(chi)(chi)的(de)(de)單位能量比目前(qian)的(de)(de)一般鋰離子(zi)電池(chi)(chi)提高(gao)了50%，其(qi)容量、充放(fang)電特(te)性(xing)(xing)、安全(quan)性(xing)(xing)、工作溫(wen)度范(fan)圍、循環壽命與環保性(xing)(xing)能等方(fang)面都(dou)較(jiao)鋰離子(zi)電池(chi)(chi)有大幅度的(de)(de)提高(gao)。
