一、電芯容額和額定容額分別是什么意思

1、電芯容額

電芯容(rong)(rong)額是(shi)指電(dian)(dian)(dian)池中實際儲(chu)存(cun)電(dian)(dian)(dian)能(neng)的(de)(de)(de)容(rong)(rong)量(liang)。電(dian)(dian)(dian)芯是(shi)電(dian)(dian)(dian)池的(de)(de)(de)核心(xin)器件(jian)，電(dian)(dian)(dian)芯容(rong)(rong)額是(shi)指電(dian)(dian)(dian)芯所擁有的(de)(de)(de)真正的(de)(de)(de)儲(chu)存(cun)電(dian)(dian)(dian)能(neng)的(de)(de)(de)容(rong)(rong)量(liang)。由于電(dian)(dian)(dian)池本身也會(hui)存(cun)在一定(ding)的(de)(de)(de)損耗，所以電(dian)(dian)(dian)池輸出的(de)(de)(de)容(rong)(rong)量(liang)常常是(shi)小于電(dian)(dian)(dian)芯容(rong)(rong)額的(de)(de)(de)。這也是(shi)為什么在市(shi)場上比(bi)較靠(kao)譜的(de)(de)(de)產品，會(hui)在包(bao)裝上標注上電(dian)(dian)(dian)芯容(rong)(rong)量(liang)，而(er)不是(shi)單純的(de)(de)(de)額定(ding)容(rong)(rong)量(liang)。

2、額定容額

額定(ding)容(rong)額是(shi)指(zhi)廠(chang)家為電(dian)(dian)(dian)池(chi)規定(ding)的(de)(de)(de)(de)標準容(rong)量，也就是(shi)電(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)正常(chang)(chang)使用(yong)容(rong)量。在低功(gong)率使用(yong)下，電(dian)(dian)(dian)池(chi)可(ke)承受最長的(de)(de)(de)(de)時間(jian)。例如，一塊(kuai)標有1500mAh的(de)(de)(de)(de)AA電(dian)(dian)(dian)池(chi)，在正常(chang)(chang)情(qing)況下，是(shi)可(ke)以提(ti)供1500毫安(an)時的(de)(de)(de)(de)電(dian)(dian)(dian)能(neng)，但(dan)在實際(ji)的(de)(de)(de)(de)使用(yong)過程中，電(dian)(dian)(dian)池(chi)提(ti)供的(de)(de)(de)(de)電(dian)(dian)(dian)能(neng)有可(ke)能(neng)會比額定(ding)容(rong)量少一些，這個因(yin)素(su)涉及到(dao)電(dian)(dian)(dian)池(chi)內阻、放電(dian)(dian)(dian)倍(bei)率等復(fu)雜因(yin)素(su)。

二、電芯容額和額定容額的區別

電芯容額往往小于額定容額。電池容額，又叫實際容額，一般指的是電池在放電的狀態下，它所具備的當前的實際容量。實際容量往往是會不斷變化的，比如在夏天氣溫較高時它的分子比較活躍，此時的電芯容額較(jiao)高，而在(zai)冬(dong)天氣溫(wen)較(jiao)低時活躍(yue)度不夠，容額就會變低。

額定(ding)容(rong)(rong)額是(shi)(shi)電池(chi)(chi)上標注的(de)(de)(de)(de)(de)(de)容(rong)(rong)量(liang)(liang)，比(bi)如我(wo)們使用(yong)的(de)(de)(de)(de)(de)(de)手機(ji)所用(yong)的(de)(de)(de)(de)(de)(de)鋰(li)電池(chi)(chi)的(de)(de)(de)(de)(de)(de)容(rong)(rong)量(liang)(liang)通常會(hui)有一個(ge)額定(ding)值。在(zai)實(shi)際(ji)使用(yong)中(zhong)，電池(chi)(chi)的(de)(de)(de)(de)(de)(de)實(shi)際(ji)容(rong)(rong)量(liang)(liang)是(shi)(shi)要比(bi)額定(ding)容(rong)(rong)額低，原因就是(shi)(shi)使用(yong)過程中(zhong)很(hen)難(nan)達到最理(li)想的(de)(de)(de)(de)(de)(de)狀態(tai)，會(hui)導(dao)致實(shi)際(ji)容(rong)(rong)量(liang)(liang)往(wang)往(wang)達不(bu)到額定(ding)容(rong)(rong)額。另外(wai)，電池(chi)(chi)額定(ding)容(rong)(rong)額是(shi)(shi)指標準(zhun)所標稱電池(chi)(chi)的(de)(de)(de)(de)(de)(de)容(rong)(rong)量(liang)(liang)值大(da)小，而(er)電芯容(rong)(rong)額是(shi)(shi)指電池(chi)(chi)在(zai)一定(ding)電流值放電時的(de)(de)(de)(de)(de)(de)實(shi)際(ji)容(rong)(rong)量(liang)(liang)大(da)小。
