目前使用相對較多的鋰電池組是磷酸鐵鋰電池組，因為大家都知道鋰電池本身的穩定性較差，相對來講其安全系數并不是很高，而磷酸鐵鋰電池則是在原有的鋰離子電池的正極材料基礎上對其進行改進，讓其的安全系數更高，常見的磷酸鐵鋰電池組正極材料有鉆酸鋰，錳酸鋰以及鎳酸鋰等等，最為常用的則是鉆酸鋰。雖然磷酸鐵鋰電池組也屬于鋰離子電池，但是從正極材料上我們可以看出，磷酸鐵鋰電池是目前鋰離子電池中穩定性較高的電池，而且就成本來講，也不算很高，所以磷酸鐵鋰電池組在一些大型工業以及移動移動基站中使用的越來越多。

但是(shi)(shi)磷酸(suan)(suan)鐵(tie)鋰(li)電(dian)(dian)池(chi)(chi)的(de)振實密度較低，也正是(shi)(shi)這(zhe)一(yi)(yi)特點(dian)(dian)決(jue)定了磷酸(suan)(suan)鐵(tie)鋰(li)電(dian)(dian)池(chi)(chi)在電(dian)(dian)動工(gong)(gong)具方面上的(de)使(shi)用有所成效(xiao)，相對(dui)(dui)來講如果將(jiang)磷酸(suan)(suan)鐵(tie)鋰(li)電(dian)(dian)池(chi)(chi)應(ying)用在手(shou)機上，那么(me)它的(de)弊端則暴露無遺，最(zui)(zui)為明顯的(de)一(yi)(yi)個缺點(dian)(dian)就(jiu)是(shi)(shi)容(rong)量(liang)不(bu)足(zu)。在工(gong)(gong)作(zuo)(zuo)的(de)時候，磷酸(suan)(suan)鐵(tie)鋰(li)電(dian)(dian)池(chi)(chi)組(zu)難(nan)免(mian)會(hui)產(chan)生(sheng)熱(re)量(liang)，一(yi)(yi)般來講，磷酸(suan)(suan)鐵(tie)鋰(li)電(dian)(dian)池(chi)(chi)組(zu)的(de)工(gong)(gong)作(zuo)(zuo)環境是(shi)(shi)-50℃到(dao)+80℃之間，但是(shi)(shi)實際(ji)情況中，磷酸(suan)(suan)鐵(tie)鋰(li)電(dian)(dian)池(chi)(chi)組(zu)在工(gong)(gong)作(zuo)(zuo)的(de)過(guo)程中以及國祚過(guo)程之后都是(shi)(shi)需要產(chan)生(sheng)熱(re)量(liang)的(de)，所以，我們(men)最(zui)(zui)好將(jiang)磷酸(suan)(suan)鐵(tie)鋰(li)電(dian)(dian)池(chi)(chi)組(zu)的(de)溫度控制在+50攝氏度之下，然而磷酸(suan)(suan)鐵(tie)鋰(li)電(dian)(dian)池(chi)(chi)組(zu)最(zui)(zui)大的(de)一(yi)(yi)個缺點(dian)(dian)就(jiu)是(shi)(shi)對(dui)(dui)于低溫的(de)耐性很低，通(tong)俗的(de)講就(jiu)是(shi)(shi)磷酸(suan)(suan)鐵(tie)鋰(li)電(dian)(dian)池(chi)(chi)組(zu)不(bu)耐低溫，所以盡(jin)量(liang)不(bu)要在超過(guo)的(de)溫度范圍內工(gong)(gong)作(zuo)(zuo)。

所以我們在使用磷酸鐵鋰電池(chi)組的(de)(de)時候要盡量把工作(zuo)環境(jing)控(kong)制在一個較好的(de)(de)溫度(du)環境(jing)之下。這樣才能讓我們的(de)(de)電池(chi)組使用的(de)(de)更持久。
