鋰電池與鉛酸電池都可作為ups電源的蓄電池，但這兩種電池有何區別呢？我們從以下幾個方面來看看：

一、在標(biao)稱電壓方面，鋰電(dian)池與鉛(qian)酸(suan)電(dian)池的標稱(cheng)電(dian)壓(ya)不同，單(dan)體(ti)鉛(qian)酸(suan)電(dian)池2.0V，單(dan)體(ti)鋰電(dian)池3.6V。

二、在(zai)能(neng)量密度方面，鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)與鉛酸電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)能(neng)量(liang)(liang)密度不同，鉛酸電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)30WH/KG，一般在(zai)50~70wh/g，能(neng)量(liang)(liang)密度低，過于笨重。而鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)110WH/KG，一般在(zai)200~260wh/g，鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)就是鉛酸的3~5倍，這就意(yi)味(wei)著相(xiang)同容量(liang)(liang)的情況下(xia)，鉛酸電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)是鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的3~5倍，所以在(zai)儲(chu)能(neng)裝置輕量(liang)(liang)化上(shang)，鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)占(zhan)居(ju)絕對優(you)勢。

三、在(zai)循環壽命方面，鋰電(dian)池(chi)的循環次(ci)(ci)數(shu)一般在2000-3000次(ci)(ci)左右。鉛酸(suan)電(dian)池(chi)平均300-500次(ci)(ci)，鋰電(dian)池(chi)多達千(qian)次(ci)(ci)以上，從鋰電(dian)自行車的兩個主流技術路線來看，三元鋰電(dian)池(chi)和磷酸(suan)鐵鋰電(dian)池(chi)區(qu)別也比較大，三元鋰電(dian)池(chi)放(fang)電(dian)壽命1000次(ci)(ci)，磷酸(suan)鐵鋰電(dian)池(chi)的壽命則(ze)可達到2000次(ci)(ci)。

四、在充電(dian)方面，鋰電(dian)(dian)(dian)池(chi)采用限壓限流法(fa)，也就是對電(dian)(dian)(dian)流和電(dian)(dian)(dian)壓均給(gei)定一個限制的閾值，而鉛酸電(dian)(dian)(dian)池(chi)的充(chong)(chong)電(dian)(dian)(dian)方法(fa)就比較多，主要有：恒流充(chong)(chong)電(dian)(dian)(dian)法(fa)、恒壓充(chong)(chong)電(dian)(dian)(dian)法(fa)、階段等(deng)流充(chong)(chong)電(dian)(dian)(dian)法(fa)和浮充(chong)(chong)。

五、在體(ti)積(ji)質量方面，一(yi)般鉛酸電(dian)池(chi)重量是(shi)16—30公斤(jin),體積(ji)較大，而鋰電(dian)池(chi)一(yi)般在2.5—3公斤(jin),體積(ji)相對較小,所以更便(bian)(bian)于搬運(yun)方便(bian)(bian)。

六、在耐用性方面，鉛酸電(dian)池(chi)一般深(shen)充(chong)深(shen)放電(dian)300次(ci)以(yi)內(nei),有記(ji)憶(yi)(yi),壽命(ming)在兩(liang)年左右。并且(qie)(qie)鉛酸電(dian)池(chi)內(nei)有液(ye)體(ti),消耗一段時間(jian)后,如果發現電(dian)池(chi)發燙或者充(chong)電(dian)時間(jian)變短,就需要(yao)補充(chong)液(ye)體(ti);而磷酸鐵鋰電(dian)池(chi)耐用性較強,消耗慢(man),充(chong)放超過500次(ci),并且(qie)(qie)無記(ji)憶(yi)(yi),一般壽命(ming)在4—5年。

七、在安全(quan)性能方面，鋰(li)電(dian)(dian)池(chi)(chi)來自(zi)于正(zheng)極材料的穩定(ding)性(xing)及可(ke)靠地安(an)全(quan)性(xing)設計，磷酸(suan)鐵鋰(li)電(dian)(dian)池(chi)(chi)已(yi)經過嚴格的安(an)全(quan)測試，即(ji)使在劇烈的碰撞中(zhong)也(ye)不會(hui)(hui)產生(sheng)爆(bao)炸，磷酸(suan)鐵鋰(li)熱(re)穩定(ding)高，電(dian)(dian)解液氧化能力(li)低，因(yin)而安(an)全(quan)性(xing)高。而鉛酸(suan)電(dian)(dian)池(chi)(chi)在充(chong)放電(dian)(dian)或者使用中(zhong)會(hui)(hui)排(pai)(pai)出氣體(ti)(ti)(ti)，如(ru)果(guo)排(pai)(pai)氣孔被堵塞，就會(hui)(hui)導致氣體(ti)(ti)(ti)排(pai)(pai)不出處發(fa)生(sheng)爆(bao)炸，內部(bu)的液體(ti)(ti)(ti)是(shi)噴濺出的電(dian)(dian)解液（稀(xi)硫(liu)酸(suan)）是(shi)有腐蝕(shi)性(xing)的液體(ti)(ti)(ti)，會(hui)(hui)對很多物體(ti)(ti)(ti)有腐蝕(shi)性(xing)，而且在充(chong)電(dian)(dian)過程中(zhong)產生(sheng)的氣體(ti)(ti)(ti)是(shi)會(hui)(hui)爆(bao)炸的。

八、在綠(lv)色環保方(fang)面，兩者綠色環(huan)(huan)保(bao)性不(bu)同。鋰(li)電(dian)池(chi)(chi)材料無(wu)(wu)任何有毒有害物質，被世(shi)界認為綠色環(huan)(huan)保(bao)電(dian)池(chi)(chi)，該電(dian)池(chi)(chi)無(wu)(wu)論在(zai)(zai)生產及(ji)使用中均無(wu)(wu)污(wu)染，符合歐(ou)洲RoHS規定(ding)，為綠色環(huan)(huan)保(bao)電(dian)池(chi)(chi)。而鉛(qian)(qian)酸電(dian)池(chi)(chi)是由鉛(qian)(qian)和硫酸構成，其中存在(zai)(zai)著大量的鉛(qian)(qian)，在(zai)(zai)廢棄后如果處理不(bu)當，將對環(huan)(huan)境造成污(wu)染。

鋰(li)電(dian)池可(ke)以做ups電(dian)源電(dian)池嗎？

經過以上分析，答案(an)是(shi)鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)可以做ups電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的。鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)是(shi)綠(lv)色(se)環保的首(shou)選電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)中不(bu)含(han)有(you)任何鉛、鎳、鉻等重(zhong)金屬（有(you)害物質），相對鉛酸電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)來講，鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的重(zhong)量輕、儲能高(gao)(gao)并且自放電(dian)(dian)(dian)(dian)(dian)(dian)低、壽命長、性(xing)(xing)能好等，但是(shi)唯一的缺(que)點價(jia)格相對較高(gao)(gao)。隨著鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)ups技(ji)術(shu)發展，鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)技(ji)術(shu)水平(ping)、性(xing)(xing)價(jia)比(bi)逐步提高(gao)(gao)、尺寸越(yue)來越(yue)小(xiao)。
