一、蓄電池和鋰電池哪個好

鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)和(he)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)兩款不(bu)同(tong)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，經常被拿(na)來(lai)作(zuo)比較(jiao)。首先是(shi)概念(nian)性(xing)質(zhi)不(bu)同(tong)，鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)一(yi)類由鋰金屬或鋰合金為負(fu)極材料、使用非水(shui)電(dian)(dian)(dian)(dian)(dian)(dian)解質(zhi)溶液的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)也稱二次電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。是(shi)將化學能(neng)直接轉化成電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)的(de)(de)一(yi)種裝(zhuang)置，是(shi)按(an)可(ke)再(zai)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)設計的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，通過可(ke)逆(ni)的(de)(de)化學反應實現(xian)再(zai)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，通常是(shi)指(zhi)鉛酸(suan)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。其(qi)次蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)和(he)鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)在安全性(xing)能(neng)、價格、綠色環保性(xing)、使用循環壽命、重量能(neng)量密(mi)度、體積(ji)能(neng)量、溫度范圍、充(chong)(chong)放電(dian)(dian)(dian)(dian)(dian)(dian)方(fang)面、內部材料等方(fang)面都存在差異。

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(chi)(chi)的(de)設計壽(shou)命是(shi)27個(ge)月(yue)，一(yi)般家庭用車(che)比(bi)較省、新車(che)的(de)電池(chi)(chi)很多用到3-4年，不(bu)過更換(huan)過一(yi)次以后一(yi)般2年左右一(yi)定要更換(huan)了。出租車(che)比(bi)較費，單班車(che)能用一(yi)年出頭(tou)，雙班車(che)8-10個(ge)月(yue)左右就(jiu)差不(bu)多需(xu)要更換(huan)了。
