核心提示： “鋰電池放電放得越盡，電池的損耗就會越大，”艾克郎大學，幫助美國太空總署NASA研究延長電池壽命的電子工程教授Tom Hartley，說到，“給電池充電充得越滿，電池的損耗也會越大。鋰電池最好是處于電量的中間狀態，那樣的話電池壽命最長。”
　　淺談鋰電(dian)池放電(dian)的誤區

　　“鋰電(dian)(dian)(dian)池放電(dian)(dian)(dian)放得越(yue)盡，電(dian)(dian)(dian)池的損耗就會越(yue)大，”艾克郎大學，幫(bang)助美(mei)國太空總署NASA研究延長(chang)電(dian)(dian)(dian)池壽命的電(dian)(dian)(dian)子工程教(jiao)授Tom Hartley，說(shuo)到，“給電(dian)(dian)(dian)池充電(dian)(dian)(dian)充得越(yue)滿，電(dian)(dian)(dian)池的損耗也會越(yue)大。鋰電(dian)(dian)(dian)池最好是處(chu)于電(dian)(dian)(dian)量的中間狀態(tai)，那樣的話電(dian)(dian)(dian)池壽命最長(chang)。”

　　首先，過高(gao)和過低的電(dian)(dian)(dian)量(liang)(liang)(liang)狀(zhuang)態(tai)對鋰(li)(li)電(dian)(dian)(dian)池的壽(shou)命(ming)有(you)最不利的影響，而充(chong)放(fang)(fang)電(dian)(dian)(dian)循(xun)環次數(shu)反而是(shi)次要 的。其實(shi)(shi)，大多數(shu)售賣電(dian)(dian)(dian)器(qi)或(huo)電(dian)(dian)(dian)池上(shang)標識的可反復充(chong)電(dian)(dian)(dian)次數(shu)，都是(shi)以放(fang)(fang)電(dian)(dian)(dian)百(bai)分之(zhi)80為基準(zhun)測試得出的。實(shi)(shi)驗表明，對于一些(xie)筆記本電(dian)(dian)(dian)腦的鋰(li)(li)電(dian)(dian)(dian)池，經常(chang)讓(rang)電(dian)(dian)(dian)池電(dian)(dian)(dian)壓 超過標準(zhun)電(dian)(dian)(dian)壓0.1伏(fu)特(te)，即從(cong)4.1伏(fu)上(shang)升到4.2伏(fu)，那么電(dian)(dian)(dian)池的壽(shou)命(ming)會減半，再提(ti)高(gao)0.1伏(fu)，則壽(shou)命(ming)減為原來的3分之(zhi)一;長(chang)期低電(dian)(dian)(dian)量(liang)(liang)(liang)或(huo)者無電(dian)(dian)(dian)量(liang)(liang)(liang)的狀(zhuang)態(tai)則 會使(shi)電(dian)(dian)(dian)池內部對電(dian)(dian)(dian)子移(yi)動的阻力越來越大，于是(shi)導致電(dian)(dian)(dian)池容(rong)量(liang)(liang)(liang)變小。美國宇航(hang)局NASA讓(rang)其哈勃太空望遠鏡上(shang)電(dian)(dian)(dian)池的消耗(hao)電(dian)(dian)(dian)量(liang)(liang)(liang)設定在總容(rong)量(liang)(liang)(liang)的百(bai)分之(zhi)10，以確保 電(dian)(dian)(dian)池可以反復充(chong)放(fang)(fang)電(dian)(dian)(dian)10萬(wan)次而不必(bi)更新(xin)。

　　其次，溫度對(dui)(dui)鋰電池(chi)(chi)壽命(ming)也(ye)有較(jiao)大的(de)影響(xiang)(手機和其他小型電子設備對(dui)(dui)此點(dian)可忽略(lve))。冰點(dian)以下的(de)環境(jing)有可能使鋰電池(chi)(chi)在電子產品打開的(de)瞬間燒(shao)毀(hui)，而過熱的(de) 環境(jing)則會(hui)(hui)縮(suo)減電池(chi)(chi)的(de)容(rong)量(liang)。因此，如果筆(bi)(bi)電長(chang)(chang)期使用(yong)外接電源也(ye)不(bu)將電池(chi)(chi)取(qu)下來，電池(chi)(chi)就(jiu)長(chang)(chang)期處(chu)于筆(bi)(bi)記本排出的(de)高熱當中，更主要(yao)的(de)是，電池(chi)(chi)長(chang)(chang)期處(chu)于百分之(zhi)100 的(de)電量(liang)狀態(tai)，很(hen)快(kuai)就(jiu)會(hui)(hui)報廢。

　　由以上(shang)，我們可以總結出以下幾點確保鋰(li)電池(chi)容量和壽命的注意(yi)事項：

　　目前(qian)大(da)多數電(dian)(dian)子產品的(de)(de)(de)(de)電(dian)(dian)池(chi)(chi)都采(cai)用鋰(li)(li)電(dian)(dian)池(chi)(chi)，鋰(li)(li)離子電(dian)(dian)池(chi)(chi)自(zi)1990年問(wen)世以來，因(yin)其(qi)卓越的(de)(de)(de)(de)性能得到(dao)了(le)迅(xun)猛(meng)的(de)(de)(de)(de)發展，并廣泛(fan)地應用于社會，鋰(li)(li)電(dian)(dian)池(chi)(chi)生產商也因(yin)此得到(dao)了(le)最大(da)規(gui)模的(de)(de)(de)(de)發展。不(bu)需(xu)要將鋰(li)(li)電(dian)(dian)池(chi)(chi)充(chong)到(dao)百(bai)分之100滿(man)電(dian)(dian)，更不(bu)要將電(dian)(dian)量使用殆(dai)盡(jin)。在情況(kuang)允許的(de)(de)(de)(de)情況(kuang)下，盡(jin)量使電(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)電(dian)(dian)量維持在半(ban)滿(man)狀態附近，充(chong)電(dian)(dian)與(yu)放(fang)電(dian)(dian)的(de)(de)(de)(de)幅(fu)度越小(xiao)越好;

　　通用(yong)Chevy Volt電(dian)(dian)動車的出廠設計就(jiu)是強(qiang)制(zhi)將電(dian)(dian)池(chi)(chi)電(dian)(dian)量維持在20%至(zhi)80%，而(er)蘋果筆電(dian)(dian)的內(nei)置電(dian)(dian)池(chi)(chi)可能也是運用(yong)了這一方法(包括其他一些筆電(dian)(dian)和電(dian)(dian)子產品)，讓(rang)電(dian)(dian)池(chi)(chi)的可充放電(dian)(dian)周期(qi)數增加。

　　不要將鋰電池(尤其是筆記本鋰電池)長期在設備使用外接電源、充電器的情況下工作。就算您的筆記本散熱良好(hao)，長期百分之100的電量就等于對鋰電池的謀(mou)殺。

　　1. 如果(guo)你長期用外接電(dian)(dian)(dian)源(yuan)為筆記(ji)本電(dian)(dian)(dian)腦供電(dian)(dian)(dian)，或(huo)者電(dian)(dian)(dian)池電(dian)(dian)(dian)量(liang)已(yi)經超過80%，馬(ma)上取下(xia)你筆記(ji)本的電(dian)(dian)(dian)池、平(ping)(ping)時充(chong)(chong)(chong)電(dian)(dian)(dian)不(bu)需將(jiang)電(dian)(dian)(dian)池充(chong)(chong)(chong)滿(man)，充(chong)(chong)(chong)至80%左右即(ji)(ji)可;調整操作系統的電(dian)(dian)(dian)源(yuan)選項(xiang)，將(jiang)電(dian)(dian)(dian)量(liang)警報調至20%以上，平(ping)(ping)時電(dian)(dian)(dian)池電(dian)(dian)(dian)量(liang)最低(di)不(bu)要(yao)低(di)于20%，在下(xia)降到(dao)20%以前即(ji)(ji)要(yao)進行(xing)充(chong)(chong)(chong)電(dian)(dian)(dian);

　　2. 手機等小型電(dian)子(zi)設備，充好電(dian)了就應立刻斷開電(dian)源線(xian)(包括充電(dian)功能的USB接口(kou))，一(yi)直接著會損害(hai)電(dian)池(chi);要(yao)經常充電(dian)，記起來就充，但不必非得把電(dian)池(chi)充滿;

　　3. 無論(lun)是對筆記本(ben)還是手機等(deng)，都(dou)一定不要讓電池耗盡;

　　4. 如果要外出旅行，用電池充電器充滿吧，但(dan)請記得在(zai)條件允許(xu)的情(qing)況下隨(sui)時為電(dian)器充電(dian)，為了電(dian)池壽命(ming)，一定不(bu)要等到電(dian)池放干(gan)。
