電池虧電是指電池深度(du)放電(dian)(dian)(dian)后（電(dian)(dian)(dian)量顯示(shi)完全沒(mei)有電(dian)(dian)(dian)了），沒(mei)有對其充電(dian)(dian)(dian)，讓(rang)其長時(shi)間處(chu)在這(zhe)樣的(de)狀態(tai)下的(de)意思，而不是指電(dian)(dian)(dian)量顯示(shi)表顯示(shi)有電(dian)(dian)(dian)量或是什(shen)么電(dian)(dian)(dian)量剩余40%的(de)狀態(tai)。那么電(dian)(dian)(dian)池長期處(chu)于(yu)虧(kui)電(dian)(dian)(dian)狀態(tai)下會發生什(shen)么不好(hao)的(de)事情呢(ni)？

電池不(bu)能長期(qi)虧電的原因有以下幾個(ge)：

1、化學反應限制

電(dian)池(chi)內部的(de)化(hua)學(xue)反(fan)應是產(chan)(chan)生電(dian)能(neng)的(de)基礎。當電(dian)池(chi)電(dian)量(liang)減(jian)少時，化(hua)學(xue)反(fan)應會逆轉(zhuan)，將(jiang)電(dian)荷(he)流回(hui)電(dian)池(chi)中。然而，這種逆轉(zhuan)反(fan)應只能(neng)持續一定(ding)時間(jian)，因為反(fan)應物會逐漸耗盡，電(dian)池(chi)內部化(hua)學(xue)反(fan)應停止，電(dian)池(chi)就無法再(zai)產(chan)(chan)生電(dian)能(neng)了。

2、內部自放電

即使電(dian)(dian)(dian)池(chi)沒(mei)有連接到負載，它(ta)仍然(ran)會(hui)自(zi)行放電(dian)(dian)(dian)。電(dian)(dian)(dian)池(chi)內部(bu)的(de)化學反應會(hui)使電(dian)(dian)(dian)荷流出電(dian)(dian)(dian)池(chi)，導致電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)量下降(jiang)。這種自(zi)放電(dian)(dian)(dian)的(de)速度通常比較緩慢，但長(chang)時間虧電(dian)(dian)(dian)會(hui)使電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)量徹底(di)耗盡。

3、電池損傷

長(chang)時間(jian)虧電(dian)(dian)會(hui)(hui)使(shi)電(dian)(dian)池內部的化學物質結(jie)構發生(sheng)改變，從而(er)損傷電(dian)(dian)池。例如(ru)(ru)，鋰離子電(dian)(dian)池如(ru)(ru)果(guo)長(chang)時間(jian)放置在低電(dian)(dian)量狀態下，其鋰離子會(hui)(hui)發生(sheng)結(jie)晶(jing)，導致(zhi)電(dian)(dian)池無法充電(dian)(dian)或(huo)損壞。

因此，長期虧電會對(dui)電池(chi)的性(xing)能和壽(shou)命產生負面(mian)影響。為(wei)了保護(hu)電池(chi)，建(jian)議(yi)在(zai)長期存儲前將電池(chi)充(chong)滿，并將其存儲在(zai)干(gan)燥、溫(wen)度適宜的環境(jing)中。
