鋰電池充電講究少食多餐,長時間充傷手機電量耗光損壽命
　　“手機電(dian)(dian)池(chi)應該(gai)用光了之(zhi)后再充電(dian)(dian)”、“過度充電(dian)(dian)電(dian)(dian)池(chi)會爆炸”……很(hen)長(chang)一(yi)段時間里(li)，關于手機電(dian)(dian)池(chi)充電(dian)(dian)的說(shuo)法眾說(shuo)紛(fen)紜，一(yi)些(xie)充電(dian)(dian)誤區經常弄(nong)得人們(men)一(yi)頭霧(wu)水。那(nei)么，如何才能正確充電(dian)(dian)，既(ji)保證安全，又能延長(chang)電(dian)(dian)池(chi)的使(shi)用壽命呢？

　　幾次(ci)完(wan)(wan)全充(chong)(chong)放(fang)電(dian)(dian)(dian)(dian)來激活(huo)。這些(xie)電(dian)(dian)(dian)(dian)池會(hui)(hui)產生“記憶(yi)效應”，在(zai)不完(wan)(wan)全放(fang)電(dian)(dian)(dian)(dian)的狀態下充(chong)(chong)電(dian)(dian)(dian)(dian)，易使電(dian)(dian)(dian)(dian)池過(guo)(guo)度(du)充(chong)(chong)電(dian)(dian)(dian)(dian)，時間長了(le)會(hui)(hui)讓使用者覺得電(dian)(dian)(dian)(dian)很快(kuai)就用完(wan)(wan)了(le)。不過(guo)(guo)，現(xian)在(zai)的手機和筆記本電(dian)(dian)(dian)(dian)腦上所用的電(dian)(dian)(dian)(dian)池，大都是(shi)鋰電(dian)(dian)(dian)(dian)池。它的初始(shi)化(hua)過(guo)(guo)程(cheng)已在(zai)制造時完(wan)(wan)成(cheng)，因此開始(shi)使用時不需(xu)要激活(huo)。

　　一般鋰電池的壽命可達到幾百次充放電循環，這里的充放電循環是指將電量用光后再充滿的過程，而不是插上充電器再拔掉就算一次。鋰電池沒有記憶效應，可以隨時充電，為了減少充電次數而刻意將電池用光后再充滿，并不能延長電池壽命，反而對電池的壽命有負面影響。鋰電池充電講究“少食多餐”，頻繁的淺度充放電更有助于延長其壽命。同時，充滿電后要盡快拔掉電源，否則電池一直保持滿電狀態，會加快電池容量的損失速度。
