一、蓄電池和鋰電池哪個好

鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)和(he)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是(shi)(shi)(shi)兩款(kuan)不同(tong)的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，經常(chang)被拿來作(zuo)比較。首先(xian)是(shi)(shi)(shi)概念性質不同(tong)，鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是(shi)(shi)(shi)一類由鋰(li)金屬或鋰(li)合金為負極(ji)材(cai)料(liao)、使(shi)用(yong)非水(shui)電(dian)(dian)(dian)(dian)(dian)解質溶液的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)也(ye)稱(cheng)二次電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。是(shi)(shi)(shi)將化(hua)學能(neng)直(zhi)接轉化(hua)成(cheng)電(dian)(dian)(dian)(dian)(dian)能(neng)的(de)一種(zhong)裝置，是(shi)(shi)(shi)按可(ke)再(zai)充(chong)電(dian)(dian)(dian)(dian)(dian)設計(ji)的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，通過(guo)可(ke)逆的(de)化(hua)學反應實現再(zai)充(chong)電(dian)(dian)(dian)(dian)(dian)，通常(chang)是(shi)(shi)(shi)指鉛(qian)酸蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。其次蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)和(he)鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)在安全性能(neng)、價(jia)格、綠色環保性、使(shi)用(yong)循環壽命、重量能(neng)量密度(du)、體積能(neng)量、溫度(du)范圍、充(chong)放電(dian)(dian)(dian)(dian)(dian)方面(mian)、內(nei)部(bu)材(cai)料(liao)等方面(mian)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

壽命(ming)蓄電池的(de)設(she)計壽命(ming)是27個月，一(yi)(yi)般家庭用車(che)(che)比較省、新車(che)(che)的(de)電池很多(duo)用到(dao)3-4年(nian)，不過(guo)更(geng)換過(guo)一(yi)(yi)次以后(hou)一(yi)(yi)般2年(nian)左右(you)一(yi)(yi)定要更(geng)換了。出(chu)租車(che)(che)比較費，單班車(che)(che)能(neng)用一(yi)(yi)年(nian)出(chu)頭，雙班車(che)(che)8-10個月左右(you)就(jiu)差不多(duo)需要更(geng)換了。
