鉛(qian)(qian)(qian)酸電(dian)池(chi)(VRLA),是一種(zhong)電(dian)極(ji)主(zhu)要由鉛(qian)(qian)(qian)及其氧(yang)化物制成(cheng),電(dian)解(jie)液是硫(liu)酸溶液的(de)蓄(xu)電(dian)池(chi)。鉛(qian)(qian)(qian)酸電(dian)池(chi)放電(dian)狀態下,正極(ji)主(zhu)要成(cheng)分為二氧(yang)化鉛(qian)(qian)(qian),負極(ji)主(zhu)要成(cheng)分為鉛(qian)(qian)(qian);充電(dian)狀態下,正負極(ji)的(de)主(zhu)要成(cheng)分均(jun)為硫(liu)酸鉛(qian)(qian)(qian)。
磷酸(suan)鐵(tie)鋰(li)(li)(li)(li)電池(chi)(chi),是指用磷酸(suan)鐵(tie)鋰(li)(li)(li)(li)作為正極(ji)材(cai)(cai)料(liao)(liao)的鋰(li)(li)(li)(li)離(li)(li)子(zi)電池(chi)(chi)。 鋰(li)(li)(li)(li)離(li)(li)子(zi)電池(chi)(chi)的正極(ji)材(cai)(cai)料(liao)(liao)主要(yao)有鈷酸(suan)鋰(li)(li)(li)(li)、錳酸(suan)鋰(li)(li)(li)(li)、鎳(nie)酸(suan)鋰(li)(li)(li)(li)、三元材(cai)(cai)料(liao)(liao)、磷酸(suan)鐵(tie)鋰(li)(li)(li)(li)等。其(qi)中(zhong)磷酸(suan)鐵(tie)鋰(li)(li)(li)(li)是目前絕大(da)多數鋰(li)(li)(li)(li)離(li)(li)子(zi)電池(chi)(chi)使用的正極(ji)材(cai)(cai)料(liao)(liao)。
鉛酸電(dian)池(chi)充(chong)(chong)放電(dian)過(guo)程中有可燃氣體氫氣析出,根(gen)據《GB 50058-2014爆(bao)(bao)炸(zha)(zha)危險環境電(dian)力裝置設計規范》附(fu)錄B《爆(bao)(bao)炸(zha)(zha)性(xing)氣體環境危險區域范圍典型示例圖》第23條(tiao)規定,屬(shu)于氣體性(xing)爆(bao)(bao)炸(zha)(zha)環境IIC級(ji)別分類(lei),為同類(lei)最高級(ji)別。易燃易爆(bao)(bao)。磷酸鐵鋰(li)電(dian)池(chi)充(chong)(chong)放電(dian)過(guo)程是鋰(li)離(li)子在正負極(ji)之(zhi)間游(you)走,無(wu)可燃氣體產生。安全(quan)可靠。
蓄(xu)電(dian)(dian)池(chi)(chi)經(jing)歷一(yi)次(ci)(ci)充(chong)電(dian)(dian)和放電(dian)(dian),稱為一(yi)次(ci)(ci)循(xun)環(huan)(huan)(一(yi)個周期)。在一(yi)定(ding)放電(dian)(dian)條件下(xia),電(dian)(dian)池(chi)(chi)工作至某一(yi)容量(liang)規定(ding)值之前,電(dian)(dian)池(chi)(chi)所能承受(shou)的循(xun)環(huan)(huan)次(ci)(ci)數(shu),稱為循(xun)環(huan)(huan)壽命(ming),各種(zhong)蓄(xu)電(dian)(dian)池(chi)(chi)使用循(xun)環(huan)(huan)次(ci)(ci)數(shu)都(dou)有差異,傳統鉛(qian)酸(suan)電(dian)(dian)池(chi)(chi)循(xun)環(huan)(huan)壽命(ming)為300~500次(ci)(ci),磷酸(suan)鐵(tie)鋰(li)(li)循(xun)環(huan)(huan)壽命(ming)為2000次(ci)(ci)以上。影(ying)響鉛(qian)酸(suan)電(dian)(dian)池(chi)(chi)循(xun)環(huan)(huan)壽命(ming)的因(yin)素一(yi)是產品(pin)的性能,二是維護(hu)工作的質量(liang),鉛(qian)酸(suan)電(dian)(dian)池(chi)(chi)每季度或半年要進行核對性充(chong)放電(dian)(dian);而磷酸(suan)鐵(tie)鋰(li)(li)電(dian)(dian)池(chi)(chi)真正(zheng)免維護(hu),降(jiang)低了(le)維護(hu)成本。
