由(you)于采(cai)用安全的“防爆"材料,鋰(li)電(dian)(dian)與空(kong)氣(qi)接(jie)觸后,空(kong)氣(qi)中(zhong)和電(dian)(dian)池內部會形(xing)成(cheng)正負(fu)極。因(yin)此(ci),即(ji)使在(zai)高(gao)溫(wen)的環(huan)境(jing)下,鋰(li)電(dian)(dian)池仍(reng)具有一(yi)定(ding)壽命。并且由(you)于其(qi)(qi)有較低的能量(liang)密度(du),因(yin)而(er)在(zai)很大(da)程度(du)上可(ke)以減(jian)少電(dian)(dian)池使用時(shi)產(chan)生的熱量(liang)并保(bao)護電(dian)(dian)池不被燒毀。目前,我國主(zhu)要采(cai)用鋰(li)離子電(dian)(dian)池,由(you)于其(qi)(qi)價(jia)格(ge)昂貴且安全問題,多數(shu)廠家均采(cai)用tan酸(suan)鋰(li)作為(wei)負(fu)極材料,導致負(fu)極材料價(jia)格(ge)較高(gao),但由(you)于其(qi)(qi)具有良(liang)好的循環(huan)性能和能量(liang)密度(du),因(yin)此(ci)成(cheng)為(wei)工業生產(chan)應用中(zhong)的主(zhu)要動力(li)來源。
礦用(yong)(yong)(yong)(yong)(yong)防(fang)爆(bao)鋰(li)(li)(li)電(dian)(dian)池的(de)工(gong)(gong)作(zuo)溫度(du)范圍寬(kuan),在(zai)(zai)-40℃~+85℃范圍內均能(neng)(neng)正常使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong),但-40℃時,鋰(li)(li)(li)離子電(dian)(dian)池就開始工(gong)(gong)作(zuo),鋰(li)(li)(li)電(dian)(dian)池也開始冒煙。為使(shi)(shi)(shi)(shi)(shi)鋰(li)(li)(li)電(dian)(dian)池能(neng)(neng)正常工(gong)(gong)作(zuo),鋰(li)(li)(li)電(dian)(dian)池必須有足夠的(de)能(neng)(neng)量(liang)(liang),以保證能(neng)(neng)夠進(jin)行(xing)充電(dian)(dian)。溫度(du)升高時,電(dian)(dian)流和(he)電(dian)(dian)壓隨(sui)之增(zeng)大(da)(da),鋰(li)(li)(li)充電(dian)(dian)的(de)能(neng)(neng)量(liang)(liang)也隨(sui)之增(zeng)加(jia)。但電(dian)(dian)壓過(guo)(guo)高或過(guo)(guo)低,都會使(shi)(shi)(shi)(shi)(shi)鋰(li)(li)(li)電(dian)(dian)池的(de)容量(liang)(liang)下降,產生(sheng)過(guo)(guo)熱;過(guo)(guo)高會使(shi)(shi)(shi)(shi)(shi)電(dian)(dian)池在(zai)(zai)充電(dian)(dian)時膨脹(zhang)爆(bao)炸,或者因過(guo)(guo)熱而(er)燒(shao)壞鋰(li)(li)(li)電(dian)(dian)池;因此使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)命會縮短。同時對電(dian)(dian)池的(de)安(an)全(quan)壽(shou)命也會造成一定程(cheng)度(du)影(ying)響。根據鋰(li)(li)(li)價格而(er)定,目(mu)前市場上有多種防(fang)爆(bao)型鋰(li)(li)(li)電(dian)(dian)池,礦用(yong)(yong)(yong)(yong)(yong)防(fang)爆(bao)鋰(li)(li)(li)電(dian)(dian)池分(fen)為單次循環(huan)使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)式(shi)和(he)多次循環(huan)使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)式(shi)(雙倍型)兩種方式(shi)。在(zai)(zai)充電(dian)(dian)時具有安(an)全(quan)可(ke)(ke)靠、容量(liang)(liang)大(da)(da)、耐高溫、使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)命長等特點(dian);可(ke)(ke)反復使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong);在(zai)(zai)使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)過(guo)(guo)程(cheng)中不會發(fa)生(sheng)危險;因此很受市場歡迎(ying),尤其是在(zai)(zai)煤礦環(huan)境下使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)價值更大(da)(da)!
