有許多消費者有這樣的經歷，在冬天，天氣較冷的時候，有時會出現手機充不了電，或者開不了機的狀況。這是什么原因呢？接下來電源適配器廠家就(jiu)來給大家講解一下吧(ba)。

許多電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)用(yong)戶(hu)并不知道，消(xiao)費(fei)級鋰(li)離子電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)在低于0℃時(shi)不能(neng)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。盡管電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組看起(qi)來在正(zheng)常充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，但(dan)在低溫充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)過(guo)程中，陽極上可能(neng)會發生金(jin)屬鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)鍍。這(zhe)個電(dian)(dian)(dian)(dian)(dian)(dian)鍍是永久的，不會伴隨充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)周期(qi)消(xiao)除。如果暴露在振動(dong)或其他壓力條件下(xia)，鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)更容易出現故障(zhang)。

 先(xian)進的(de)(de)(de)充(chong)(chong)電(dian)器可以(yi)(yi)防止鋰(li)離子電(dian)池在(zai)(zai)(zai)低于結冰(bing)(bing)溫(wen)度(du)時(shi)(shi)充(chong)(chong)電(dian)。  對低于冰(bing)(bing)凍溫(wen)度(du)的(de)(de)(de)鋰(li)離子電(dian)池充(chong)(chong)電(dian)，正在(zai)(zai)(zai)取得進展。對于大(da)多數鋰(li)離子電(dian)池來說，充(chong)(chong)電(dian)確實是(shi)可能的(de)(de)(de)，但是(shi)以(yi)(yi)非常低的(de)(de)(de)電(dian)流(liu)(liu)進行(xing)。例(li)如(ru)：2500mAh的(de)(de)(de)電(dian)池在(zai)(zai)(zai)零下30 度(du)時(shi)(shi)需要(yao)以(yi)(yi)50mA的(de)(de)(de)電(dian)流(liu)(liu)充(chong)(chong)電(dian)，在(zai)(zai)(zai)這樣低的(de)(de)(de)電(dian)流(liu)(liu)下，充(chong)(chong)電(dian)時(shi)(shi)間需要(yao)延長到50小時(shi)(shi)以(yi)(yi)上。

所(suo)以在冬天的(de)(de)時候當室內溫度(du)過低的(de)(de)時候我們就(jiu)(jiu)會發現手機充不了(le)電(dian)或者充電(dian)很慢(man)的(de)(de)情況。以后再(zai)遇(yu)到這種情況也不必太過擔(dan)心(xin)了(le)，就(jiu)(jiu)像電(dian)源(yuan)適配器廠(chang)家說的(de)(de)一樣，這是一種正常現象。
