電(dian)池內部采(cai)用化學物質構成,在與酸(suan)堿性、帶鹽物或者水中(zhong)時,容易不(bu)穩定發生化學反應(ying)或者短路(lu),損壞電(dian)池甚至發生燃燒(shao)和爆炸。不(bu)同(tong)電(dian)池會有不(bu)同(tong)的(de)充(chong)(chong)電(dian)器(qi),一定要使(shi)用原裝的(de)充(chong)(chong)電(dian)器(qi)。不(bu)匹配的(de)充(chong)(chong)電(dian)器(qi)不(bu)僅(jin)影響充(chong)(chong)電(dian)速(su)度,還(huan)損壞電(dian)瓶,使(shi)電(dian)瓶壽(shou)命縮短。
鋰電(dian)池在一定溫度下會因熱漲冷縮產(chan)生膨脹,同時(shi)(shi)膨脹體積大(da)時(shi)(shi)會爆(bao)炸,炎熱的(de)(de)天氣,再加上充電(dian)時(shi)(shi)候產(chan)生的(de)(de)熱量,會導致電(dian)池表(biao)面的(de)(de)溫度非常高,燙化電(dian)池表(biao)面的(de)(de)保(bao)護殼,甚至是起火,所以充電(dian)的(de)(de)時(shi)(shi)候一定要在陰涼通風的(de)(de)地方充電(dian)。
充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)是電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)重(zhong)復使用的重(zhong)要步驟,鋰(li)離子電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)過程分為(wei)兩個階(jie)段(duan)(duan):恒(heng)流(liu)(liu)快充(chong)(chong)階(jie)段(duan)(duan)和恒(heng)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)遞減階(jie)段(duan)(duan)。恒(heng)流(liu)(liu)快充(chong)(chong)階(jie)段(duan)(duan),電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)逐步升(sheng)高到(dao)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的標準(zhun)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya),隨后在控(kong)制芯(xin)片下轉(zhuan)入(ru)恒(heng)壓(ya)(ya)階(jie)段(duan)(duan),電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)不再升(sheng)高以(yi)確(que)保不會(hui)過充(chong)(chong),電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)則隨著(zhu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)量(liang)的上升(sheng)逐步減弱到(dao)設(she)定的值(zhi),而最(zui)終完成充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)(dian)量(liang)統計芯(xin)片通過記錄放電(dian)(dian)(dian)(dian)(dian)曲(qu)線可以(yi)抽樣(yang)計算出電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的電(dian)(dian)(dian)(dian)(dian)量(liang)。鋰(li)離子電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)在多次使用后,放電(dian)(dian)(dian)(dian)(dian)曲(qu)線會(hui)發生(sheng)改變,鋰(li)離子電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)雖然不存在記憶效應,但(dan)是充(chong)(chong)、放電(dian)(dian)(dian)(dian)(dian)不當會(hui)嚴重(zhong)影響(xiang)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)性能。
