現在的鋰電(dian)池與鎳氫電(dian)池的對(dui)比(bi)主要如(ru)下(xia):

使用范圍的對比

鋰(li)電(dian)(dian)(dian)(dian)池(chi)和鎳氫(qing)(qing)電(dian)(dian)(dian)(dian)池(chi)的(de)比(bi)(bi)較在(zai)于(yu)，鋰(li)電(dian)(dian)(dian)(dian)池(chi)在(zai)電(dian)(dian)(dian)(dian)流量(liang)(liang)(liang)小的(de)產品(pin)上（比(bi)(bi)如手(shou)機(ji)(ji)）使(shi)用比(bi)(bi)較合適，但如果使(shi)用在(zai)電(dian)(dian)(dian)(dian)流量(liang)(liang)(liang)大(da)(da)(da)的(de)產品(pin)（比(bi)(bi)如數字相(xiang)(xiang)機(ji)(ji)）上，由于(yu)電(dian)(dian)(dian)(dian)流量(liang)(liang)(liang)的(de)需求較大(da)(da)(da)，而(er)且(qie)耗電(dian)(dian)(dian)(dian)量(liang)(liang)(liang)也比(bi)(bi)手(shou)機(ji)(ji)大(da)(da)(da)很多，鋰(li)電(dian)(dian)(dian)(dian)池(chi)供不應(ying)求，所以相(xiang)(xiang)對于(yu)電(dian)(dian)(dian)(dian)流量(liang)(liang)(liang)大(da)(da)(da)，容量(liang)(liang)(liang)大(da)(da)(da)，能(neng)量(liang)(liang)(liang)密度大(da)(da)(da)，電(dian)(dian)(dian)(dian)量(liang)(liang)(liang)輸出大(da)(da)(da)的(de)鎳氫(qing)(qing)電(dian)(dian)(dian)(dian)池(chi)會(hui)更好用一些(xie)。

優勢與缺陷的對比

鋰電池

優勢： 沒有任(ren)何記(ji)憶(yi)效應（指的(de)(de)是(shi)如果電池(chi)屬鎳鎘電池(chi)，長期不充電、放(fang)電，易在電池(chi)內(nei)留(liu)下痕跡，降低電池(chi)容量(liang)的(de)(de)現(xian)象。另外(wai)一種解(jie)釋說的(de)(de)是(shi)：電池(chi)好像記(ji)憶(yi)用戶日常的(de)(de)充、放(fang)電幅度和模式，日久(jiu)就很(hen)難改變這種模式，不能再做(zuo)大幅度充電或放(fang)電。），重(zhong)量(liang)輕。

缺陷： 成(cheng)本高，電流量不(bu)大，不(bu)耐過飽(bao)充(與(yu)鎳氫電池相比) 。

鎳氫電池

優勢： 價格便宜，通用性強，電流(liu)量(liang)大，環(huan)保不污染，穩定性好。

缺陷： 重量(liang)大，電池(chi)壽命較短(duan)。

充電模式的對比

鎳氫電池充電器與鋰電池充(chong)電(dian)器(qi)的(de)設(she)計在原(yuan)理上都(dou)是(shi)以(yi)電(dian)壓(ya)為依據(ju)的(de)，而(er)針對有無記憶效應的(de)設(she)計的(de)充(chong)電(dian)方案也(ye)是(shi)不(bu)同。

在電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)方面，鎳氫電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)終止電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)一(yi)般(ban)設置為1.4V，有的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)還可以(yi)(yi)向(xiang)(xiang)上或向(xiang)(xiang)下(xia)延展一(yi)點，根據(ju)電(dian)(dian)(dian)(dian)(dian)(dian)池的(de)(de)狀況，電(dian)(dian)(dian)(dian)(dian)(dian)池放電(dian)(dian)(dian)(dian)(dian)(dian)如果低于1.1V也(ye)有充(chong)(chong)不(bu)進電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)可能(neng)，最高(gao)的(de)(de)1.4V則(ze)是正常情況下(xia)不(bu)能(neng)突破的(de)(de)上限。對于鎳氫電(dian)(dian)(dian)(dian)(dian)(dian)池來說(shuo)，在1.1V放電(dian)(dian)(dian)(dian)(dian)(dian)意義(yi)不(bu)大，因為在充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時并(bing)不(bu)能(neng)得到容量(liang)補充(chong)(chong)。鋰電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)一(yi)般(ban)是一(yi)對一(yi)生產(chan)，也(ye)就是說(shuo)，單(dan)節鋰電(dian)(dian)(dian)(dian)(dian)(dian)池以(yi)(yi)額定電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)3.6V~3.7V，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)終止電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)4.1V~4.2V來設計，不(bu)同的(de)(de)串聯與并(bing)聯情況，鋰電(dian)(dian)(dian)(dian)(dian)(dian)池組(zu)設計的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)也(ye)不(bu)大相似。

在使用中，由于鋰電池與鎳氫電池的內部結構不同，鋰電池的構成材料是活性物質，因而并沒有記憶效應，切忌過充。而鎳氫電池就(jiu)不同，經(jing)過(guo)一定長(chang)時間(jian)的(de)循環后，其(qi)電(dian)(dian)解液會產生結晶，阻止(zhi)充(chong)(chong)(chong)電(dian)(dian)器將(jiang)電(dian)(dian)充(chong)(chong)(chong)滿，這就(jiu)是(shi)記憶效應開始發生作(zuo)用了(le)。正(zheng)確的(de)做法(fa)是(shi)激(ji)(ji)活，激(ji)(ji)活又分兩種，一種是(shi)在(zai)容(rong)量(liang)(liang)未損失(shi)(shi)的(de)情況(kuang)下的(de)完全充(chong)(chong)(chong)放(fang)電(dian)(dian)，第二種是(shi)在(zai)容(rong)量(liang)(liang)損失(shi)(shi)發生后，如(ru)果容(rong)量(liang)(liang)損失(shi)(shi)1/10以(yi)上，這近于不可使用了(le)，此時可用1.5倍的(de)充(chong)(chong)(chong)電(dian)(dian)時間(jian)激(ji)(ji)活其(qi)內(nei)部已(yi)然結晶的(de)物質，從而重新啟動鎳氫電(dian)(dian)池，相應的(de)，充(chong)(chong)(chong)電(dian)(dian)過(guo)程也伴隨電(dian)(dian)壓的(de)升(sheng)高，鎳氫電(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)器的(de)終止(zhi)電(dian)(dian)壓設計為1.4V為這種1.5倍時長(chang)的(de)充(chong)(chong)(chong)電(dian)(dian)準備了(le)條件。

現在一些充電(dian)器也提供了(le)(le)充電(dian)保護方式(shi),會(hui)根據電(dian)池(chi)(chi)的(de)電(dian)量是否充滿調(diao)理充電(dian)模(mo)式(shi),能夠有(you)效的(de)保護電(dian)池(chi)(chi)。鋰離子電(dian)池(chi)(chi)可(ke)隨用隨充，對壽(shou)命的(de)影(ying)響不大，對PPC等帶電(dian)量計電(dian)池(chi)(chi)，建議(yi)用到沒(mei)電(dian)后(hou)充電(dian)，避(bi)免影(ying)響。可(ke)隨時(shi)充電(dian)、可(ke)隨時(shi)間斷，假如滿電(dian)了(le)(le)繼續充電(dian)，會(hui)對電(dian)池(chi)(chi)壽(shou)命產生(sheng)影(ying)響。

首先要將電池完全放電，必須放電約24小時，等到完全放電后，再充滿電，這樣多次循環，即恢復電池容量，又可避免電池過充，除非電池已經損壞。不過，要避免該現象產生的最佳方法，仍然建議您選擇鎳氫電池或是鋰電池。
