鋰電池和蓄電池是我們日常經常用的電池,我們也非常關心它的安全性問題。凡事有個比較,常用的電池鋰電池和鉛酸蓄電池到底哪個更安全呢?而且為什么一個比另一個更安全?
下面就讓電池生產廠家朗達小編和大家說說吧!
一、影響電池安全的因素(su)
鋰離子(zi)電(dian)池(chi)(chi)儲存(cun)的總能(neng)量(liang)與其安(an)全性成反比。隨(sui)著(zhu)電(dian)池(chi)(chi)容(rong)量(liang)的增(zeng)加,電(dian)池(chi)(chi)體(ti)積也在增(zeng)大,其散熱(re)性能(neng)變差,發生事(shi)故的可能(neng)性也會大大增(zeng)加。對(dui)于大容(rong)量(liang)鋰離子(zi)電(dian)池(chi)(chi),尤其是汽車(che)電(dian)池(chi)(chi),采(cai)用強制(zhi)散熱(re)尤為重要。有(you)時,盡(jin)管(guan)電(dian)池(chi)(chi)本身有(you)安(an)全控制(zhi)措施,但由于某(mou)些原因,控制(zhi)失敗(bai),缺少安(an)全閥或無法通過安(an)全閥釋放氣(qi)體(ti),電(dian)池(chi)(chi)外部壓力會急劇(ju)上升,并(bing)導致爆炸。
二(er)、鉛(qian)酸蓄電池更安全一(yi)些(xie)
鉛酸(suan)蓄電(dian)池(chi)(chi)更安全(quan)。鋰離(li)子(zi)電(dian)池(chi)(chi)儲存的總能(neng)量與其安全(quan)性(xing)成反(fan)比。隨著(zhu)電(dian)池(chi)(chi)容(rong)量的增加,電(dian)池(chi)(chi)體積也(ye)在增大,其散熱性(xing)能(neng)變差,發(fa)生事故的可(ke)能(neng)性(xing)也(ye)會大大增加。對于大容(rong)量鋰離(li)子(zi)電(dian)池(chi)(chi),尤其是汽車(che)電(dian)池(chi)(chi),采用強(qiang)制散熱尤為(wei)重要(yao)。
有(you)時,盡管電(dian)(dian)(dian)池(chi)(chi)本身有(you)安全(quan)控(kong)制措施,但由于(yu)某些原因(yin),控(kong)制失敗。如果沒有(you)安全(quan)閥(fa)(fa)或無法通過(guo)安全(quan)閥(fa)(fa)釋放氣體,蓄電(dian)(dian)(dian)池(chi)(chi)的外部(bu)壓力將急劇(ju)升高并導致(zhi)爆炸(zha)。鉛酸(suan)蓄電(dian)(dian)(dian)池(chi)(chi)相對(dui)安全(quan)。維護簡(jian)單,使(shi)用(yong)(yong)壽(shou)命長。采用(yong)(yong)鉛鈣合(he)金胸板,防腐(fu)結構。閥(fa)(fa)控(kong)鉛酸(suan)蓄電(dian)(dian)(dian)池(chi)(chi)可(ke)浮充電(dian)(dian)(dian)10-15年。質量穩(wen)定,可(ke)靠(kao)性高。VRLA電(dian)(dian)(dian)池(chi)(chi)具有(you)先(xian)進的生產技術和(he)(he)嚴(yan)格的質量控(kong)制體系(xi),質量穩(wen)定,性能可(ke)靠(kao)。電(dian)(dian)(dian)壓、容量和(he)(he)密封應在(zai)線(xian)路之上進行100%檢查(cha)。所有(you)閥(fa)(fa)控(kong)密封鉛酸(suan)蓄電(dian)(dian)(dian)池(chi)(chi)均通過(guo)UL認證。總(zong)的而言鉛酸(suan)蓄電(dian)(dian)(dian)池(chi)(chi)稍勝一(yi)籌,而使(shi)用(yong)(yong)鋰電(dian)(dian)(dian)池(chi)(chi)那(nei)就(jiu)要在(zai)保(bao)證鋰電(dian)(dian)(dian)池(chi)(chi)安全(quan)措施上多(duo)花(hua)一(yi)些心思!
