不同型號(hào)(特別是不同體積)的電池,他的容量越高,提供使用的時(shí)間越長.拋開體積和重量的因素,當(dāng)然容量越高越好. 但是同樣的電池型號(hào),標(biāo)稱容量(比如600mAh)也相同,鋰離子電池實(shí)際測(cè)的初始容量不同:比如一個(gè)為660mAh,另一個(gè)是605mAh,那么660mAh的就比605mAh的好嗎. 實(shí)際情況可能是容量高的是因?yàn)殡姌O材料中多了增加初始容量的東西,而減少了電極穩(wěn)定用的東西,其結(jié)果就是循環(huán)使用幾十次以后,容量高的電池迅速容量衰竭,而容量低的電池卻依然堅(jiān)挺.許多國內(nèi)的電芯廠家往往以這個(gè)方式來獲得高容量的電池.而用戶使用半年以后待機(jī)時(shí)間卻是差得一塌糊涂. 民用的那些AA鎳氫電池(就是五號(hào)電池),一般18650鋰電池是1400mAh,卻也有標(biāo)超高容量的(1600mAh),道理也是一樣. 其實(shí):提高容量的代價(jià)就是犧牲循環(huán)壽命,廠家不在電池材料的改性上下文章,是不可能真正"提高"電池容量的
