電池是用于儲存能量以備設備使用。電池將(jiang)電(dian)(dian)(dian)能轉換(huan)為(wei)化(hua)學能，并且如果(guo)需要，可提供反向轉換(huan)。通過電(dian)(dian)(dian)流為(wei)電(dian)(dian)(dian)池充電(dian)(dian)(dian)。作為(wei)誘導(dao)化(hua)學反應(ying)的結(jie)果(guo)，一個電(dian)(dian)(dian)極獲得正電(dian)(dian)(dian)荷(he)而另一個獲得負(fu)電(dian)(dian)(dian)荷(he)。電(dian)(dian)(dian)池的特征在于以下主(zhu)要參數(shu)如電(dian)(dian)(dian)氣(qi)設備：電(dian)(dian)(dian)化(hua)學系統，電(dian)(dian)(dian)壓(ya)，電(dian)(dian)(dian)容，內阻，自放電(dian)(dian)(dian)電(dian)(dian)(dian)流和壽命。

電(dian)(dian)(dian)(dian)池(chi)容(rong)(rong)(rong)(rong)(rong)量(liang)(liang)是完全充電(dian)(dian)(dian)(dian)的(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)必須具有的(de)(de)(de)能量(liang)(liang)。在(zai)實(shi)(shi)際(ji)計算中，電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)(rong)通常(chang)以(yi)安培為單(dan)位(wei)。安培小時表示電(dian)(dian)(dian)(dian)池(chi)在(zai)1安培電(dian)(dian)(dian)(dian)流下工作(zuo)的(de)(de)(de)時間(jian)。但(dan)是，現代移動設備(bei)使(shi)用的(de)(de)(de)電(dian)(dian)(dian)(dian)流要低得多，因此電(dian)(dian)(dian)(dian)池(chi)容(rong)(rong)(rong)(rong)(rong)量(liang)(liang)通常(chang)以(yi)毫安（或mAh）為單(dan)位(wei)。額定容(rong)(rong)(rong)(rong)(rong)量(liang)(liang)始終顯(xian)示在(zai)電(dian)(dian)(dian)(dian)池(chi)本身或包裝上(shang)。但(dan)是，實(shi)(shi)際(ji)容(rong)(rong)(rong)(rong)(rong)量(liang)(liang)并不總是與標稱(cheng)值(zhi)相匹配。實(shi)(shi)際(ji)電(dian)(dian)(dian)(dian)池(chi)容(rong)(rong)(rong)(rong)(rong)量(liang)(liang)實(shi)(shi)際(ji)上(shang)在(zai)標稱(cheng)值(zhi)的(de)(de)(de)80％和110％之間(jian)。比(bi)容(rong)(rong)(rong)(rong)(rong)量(liang)(liang)指(zhi)的(de)(de)(de)是電(dian)(dian)(dian)(dian)池(chi)容(rong)(rong)(rong)(rong)(rong)量(liang)(liang)與尺寸或質(zhi)量(liang)(liang)的(de)(de)(de)比(bi)率(lv)。循環次數指(zhi)的(de)(de)(de)是電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)一次充電(dian)(dian)(dian)(dian)和放電(dian)(dian)(dian)(dian)次數。

記(ji)憶效應(ying)指的(de)是操作(zuo)期間(jian)電(dian)池(chi)(chi)(chi)容量的(de)損失。這表明電(dian)池(chi)(chi)(chi)具有(you)適應(ying)其工作(zuo)一段時間(jian)的(de)工作(zuo)循(xun)(xun)環的(de)趨(qu)勢。這意味著(zhu)如果您在(zai)沒有(you)完全放(fang)電(dian)的(de)情況下對電(dian)池(chi)(chi)(chi)充電(dian)幾次，容量將會降(jiang)低，因為您將能夠記(ji)住(zhu)該(gai)狀(zhuang)況然(ran)后將其完全放(fang)電(dian)。隨著(zhu)充電(dian)/放(fang)電(dian)循(xun)(xun)環次數的(de)增(zeng)加，記(ji)憶效應(ying)變得更加明顯。

在電(dian)池(chi)(chi)內(nei)部(bu)的這些操作(zuo)條件下(xia)(xia)，板表(biao)面(mian)的晶(jing)體(ti)(ti)增加，這減小(xiao)了電(dian)極的表(biao)面(mian)。在內(nei)部(bu)工作(zuo)物(wu)質的小(xiao)晶(jing)體(ti)(ti)形成(cheng)(cheng)的情(qing)況下(xia)(xia)，由電(dian)池(chi)(chi)的表(biao)面(mian)積最(zui)大(da)(da)，電(dian)池(chi)(chi)存儲的最(zui)大(da)(da)能量也是最(zui)大(da)(da)的。在操作(zuo)期(qi)間晶(jing)體(ti)(ti)形成(cheng)(cheng)的放大(da)(da) – 電(dian)極的表(biao)面(mian)積減小(xiao)并(bing)且實際容量因此降低。
