鐵鋰放電(dian)(dian)(dian)(dian)(dian)(dian)曲線很平直，只靠電(dian)(dian)(dian)(dian)(dian)(dian)壓來(lai)判斷電(dian)(dian)(dian)(dian)(dian)(dian)量是不(bu)(bu)可能(neng)(neng)(neng)的(de)，均衡只能(neng)(neng)(neng)靠單體補滿(man)電(dian)(dian)(dian)(dian)(dian)(dian)來(lai)均衡，補滿(man)后放電(dian)(dian)(dian)(dian)(dian)(dian)還不(bu)(bu)均衡，就(jiu)(jiu)(jiu)是單體內阻(zu)和容(rong)(rong)量不(bu)(bu)一(yi)致了(le)(le)，只能(neng)(neng)(neng)靠分容(rong)(rong)更換(huan)來(lai)解(jie)決，別無他(ta)法(fa)。先串(chuan)聯一(yi)個電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)直接從(cong)(cong)電(dian)(dian)(dian)(dian)(dian)(dian)池那(nei)里充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)半(ban)小時，保護(hu)板就(jiu)(jiu)(jiu)打開了(le)(le)。再從(cong)(cong)保護(hu)板充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)口(kou)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，或者想辦(ban)法(fa)從(cong)(cong)放電(dian)(dian)(dian)(dian)(dian)(dian)口(kou)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)半(ban)小時，就(jiu)(jiu)(jiu)可以(yi)正(zheng)常充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)了(le)(le)。需要從(cong)(cong)放電(dian)(dian)(dian)(dian)(dian)(dian)口(kou)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，注意(yi)極性不(bu)(bu)要弄反了(le)(le)，如(ru)果紅燈了(le)(le)，就(jiu)(jiu)(jiu)行了(le)(le)。也可以(yi)用另一(yi)組電(dian)(dian)(dian)(dian)(dian)(dian)池組給(gei)他(ta)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，36/48 的(de)都(dou)行，電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu) 50 歐 100 歐 200 歐都(dou)行，把電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)到(dao) 30v 以(yi)上(shang)就(jiu)(jiu)(jiu)可以(yi)正(zheng)常充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)了(le)(le)，手靠近(jin)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)會熱的(de)，不(bu)(bu)能(neng)(neng)(neng)太熱。磷酸鐵鋰電(dian)(dian)(dian)(dian)(dian)(dian)池鼓包主要有四大因(yin)素造成。

1、過充導致的(de)鋰離子電池鼓包

過(guo)度(du)充電會導致正極(ji)材(cai)料里(li)的(de)鋰原(yuan)(yuan)子全部(bu)跑到負極(ji)材(cai)料里(li)面，導致正極(ji)原(yuan)(yuan)本飽滿的(de)柵格(ge)發生(sheng)變形垮塌，這也是磷酸(suan)鐵(tie)鋰離(li)子電池(chi)包(bao)電量下(xia)降的(de)一個(ge)重要原(yuan)(yuan)因(yin)。在這個(ge)過(guo)程中，負極(ji)的(de)鋰離(li)子越來(lai)越多，過(guo)度(du)堆積使得鋰原(yuan)(yuan)子長出樹樁結晶，使得鋰離(li)子電池(chi)包(bao)發生(sheng)鼓脹。

2、過(guo)放導(dao)致的鼓(gu)包

在液態鋰離子電池充放電過程中，電極材料與電解液在固液相界面上發生反應，形成一層覆蓋于電極材料表面的鈍化層。形成的鈍化層膜能有效地阻止電解液分子的通過，但Li+卻可以經過該鈍化層自由地嵌入和脫出，具有固體電解質的特點，因此這層鈍化膜被稱為SEI。

SEI膜并(bing)非一成不(bu)變，在充放(fang)電(dian)過(guo)程中會有(you)少許的變化，重要(yao)是部(bu)分有(you)機物會發生可(ke)逆的變化。磷(lin)酸鐵鋰離子電(dian)池包(bao)過(guo)度放(fang)電(dian)后使得SEI膜發生可(ke)逆性破(po)環，保(bao)護負極材料(liao)的SEI破(po)壞后使得負極材料(liao)崩塌，從(cong)而形成鼓包(bao)現象。

3、制(zhi)造水平問題

鋰離(li)子電池鼓包可(ke)能是磷酸鐵鋰離(li)子電池包制造水平的問(wen)題，電極涂層不均勻，生(sheng)產工(gong)藝比較(jiao)粗糙(cao)。

4、久(jiu)置不用

長時間不用也會發生(sheng)鼓包的(de)現象，因為空氣(qi)在一(yi)定程度上是導電(dian)的(de)，因此，放(fang)的(de)時間過長就(jiu)相當于電(dian)池的(de)正負(fu)極直接接觸，進行(xing)了慢性的(de)短(duan)路。

以上(shang)就是朗達鋰(li)電(dian)池(chi)對(dui)于磷酸(suan)鐵鋰(li)電(dian)池(chi)鼓包(bao)原因的(de)簡單講(jiang)解(jie)，如需(xu)要了解(jie)更(geng)多關于鋰(li)電(dian)池(chi)的(de)知識可以關注我們喔！
