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)應該用光了之后再充(chong)電(dian)(dian)”、“過度充(chong)電(dian)(dian)電(dian)(dian)池(chi)會(hui)爆(bao)炸”……很(hen)長(chang)一段時(shi)間里，關(guan)于(yu)手機電(dian)(dian)池(chi)充(chong)電(dian)(dian)的說法眾說紛紜，一些充(chong)電(dian)(dian)誤(wu)區經常弄(nong)得人們一頭霧(wu)水。那(nei)么，如何才能正確充(chong)電(dian)(dian)，既保證安全，又能延長(chang)電(dian)(dian)池(chi)的使用壽命呢？

　　幾(ji)次(ci)完(wan)(wan)全(quan)充(chong)(chong)放電(dian)(dian)來激活。這些(xie)電(dian)(dian)池(chi)(chi)會產生(sheng)“記憶(yi)效(xiao)應”，在不(bu)(bu)完(wan)(wan)全(quan)放電(dian)(dian)的(de)(de)狀態下充(chong)(chong)電(dian)(dian)，易使(shi)電(dian)(dian)池(chi)(chi)過度充(chong)(chong)電(dian)(dian)，時間長了(le)會讓使(shi)用(yong)者覺(jue)得電(dian)(dian)很快就用(yong)完(wan)(wan)了(le)。不(bu)(bu)過，現在的(de)(de)手機和(he)筆記本電(dian)(dian)腦上所用(yong)的(de)(de)電(dian)(dian)池(chi)(chi)，大都(dou)是鋰電(dian)(dian)池(chi)(chi)。它的(de)(de)初(chu)始化過程(cheng)已在制造時完(wan)(wan)成，因此開始使(shi)用(yong)時不(bu)(bu)需要激活。

　　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。
