一、蓄電池和鋰電池哪個好

鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)和蓄(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是(shi)(shi)(shi)兩款不同的電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，經常(chang)被拿來作比(bi)較。首先是(shi)(shi)(shi)概念(nian)性質不同，鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是(shi)(shi)(shi)一類由鋰(li)金屬(shu)或鋰(li)合金為負極材料(liao)、使用非(fei)水電(dian)(dian)(dian)(dian)解質溶液的電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。蓄(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)也稱二次電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。是(shi)(shi)(shi)將化學能(neng)直(zhi)接轉化成電(dian)(dian)(dian)(dian)能(neng)的一種(zhong)裝置，是(shi)(shi)(shi)按可再(zai)充電(dian)(dian)(dian)(dian)設計的電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，通過(guo)可逆(ni)的化學反(fan)應(ying)實現再(zai)充電(dian)(dian)(dian)(dian)，通常(chang)是(shi)(shi)(shi)指鉛酸蓄(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。其次蓄(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)和鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)在安全性能(neng)、價(jia)格、綠(lv)色環(huan)(huan)保性、使用循環(huan)(huan)壽命(ming)、重量能(neng)量密度、體積能(neng)量、溫度范(fan)圍(wei)、充放電(dian)(dian)(dian)(dian)方面、內部材料(liao)等方面都存在差(cha)異。

二、蓄電池怎么充電

蓄電池投進使用后，必須定期地進行充電和放電。充電的目的是使蓄電池貯存電能及時地恢復容量，以滿足用電設備的需要。放電的目的是及時地檢驗蓄電池容量參數，及促進電極活性物質的活化反應。蓄電池充電和放電狀況的好壞，將直接影響到蓄電池的電性能及使用壽命。目前對蓄電池充電的方法很多，如恒定電流充電法、恒定電壓充電法、有固定電阻的恒定電壓充電、階段等流充電法、浮充電法等幾種。選擇科學公道的充電方法將會大大進步蓄電池的維護效果。想要延長蓄電池使用壽命，除了定期充放電外，還要在選擇時優先選知名蓄電池品牌。

三、蓄電池壽命一般是幾年

壽(shou)命蓄電池的(de)(de)設計壽(shou)命是(shi)27個月，一般(ban)家庭用車比較省、新車的(de)(de)電池很多(duo)用到3-4年(nian)(nian)，不過更(geng)換過一次以后一般(ban)2年(nian)(nian)左(zuo)右(you)一定要(yao)更(geng)換了(le)。出(chu)租車比較費(fei)，單班車能(neng)用一年(nian)(nian)出(chu)頭，雙班車8-10個月左(zuo)右(you)就差(cha)不多(duo)需要(yao)更(geng)換了(le)。
