　　鋰(li)(li)離子(zi)(zi)(zi)電(dian)池(chi)具有單只端電(dian)壓(ya)高、比(bi)容量(liang)大(da)等(deng)優點，但其充(chong)(chong)(chong)電(dian)必須使(shi)用(yong)專用(yong)充(chong)(chong)(chong)電(dian)器，因為它在過充(chong)(chong)(chong)電(dian)時極易損壞。鋰(li)(li)離子(zi)(zi)(zi)電(dian)池(chi)充(chong)(chong)(chong)電(dian)器之所以(yi)稱“新創意”，是(shi)因為它除監視電(dian)池(chi)的充(chong)(chong)(chong)電(dian)狀態(tai)外，還能分階(jie)段控制(zhi)電(dian)池(chi)的最大(da)充(chong)(chong)(chong)電(dian)電(dian)流。用(yong)本充(chong)(chong)(chong)電(dian)器充(chong)(chong)(chong)電(dian)開始時，充(chong)(chong)(chong)電(dian)電(dian)流從10mA依(yi)次遞增至(zhi)270mA，當電(dian)量(liang)充(chong)(chong)(chong)至(zhi)70%左右時，自動改用(yong)最大(da)220mA充(chong)(chong)(chong)電(dian)，然后依(yi)次改為最大(da)170mA、120mA和70mA，最后以(yi)10mA左右的涓(juan)流結束(shu)充(chong)(chong)(chong)電(dian)。這(zhe)種充(chong)(chong)(chong)電(dian)方法(fa)可以(yi)較大(da)限度地(di)將鋰(li)(li)離子(zi)(zi)(zi)電(dian)池(chi)充(chong)(chong)(chong)足。
