一、18650鋰電池能耐多少度溫度
隨著鋰離子電池工業的繼續發展,目前在市場中,鋰離子電池憑借著眾多的優點被普及。2010年起,投放1000多億元在鋰離子電池市場,促使了鋰離子電池的快速發展和使用。其中18650鋰電池是一種圓柱形鋰電池,直徑為18毫米,高度為65.0毫米,額定電壓為3.7V,那么18650鋰電池能耐多(duo)少度(du)溫度(du)呢?
過電(dian)(dian)溫(wen)(wen)度(du)(du)范圍(wei):0℃—+60℃、充(chong)電(dian)(dian)溫(wen)(wen)度(du)(du):0℃—+45℃、工作(zuo)溫(wen)(wen)度(du)(du):-20℃-50℃,最佳工作(zuo)溫(wen)(wen)度(du)(du)為(wei)20℃-40℃,60攝(she)(she)氏(shi)度(du)(du)是保證電(dian)(dian)池壽(shou)命的溫(wen)(wen)度(du)(du),高溫(wen)(wen)會折壽(shou),高于100攝(she)(she)氏(shi)度(du)(du)才會有危險(xian),一般140攝(she)(she)氏(shi)度(du)(du)會燃(ran)燒(shao)或者爆炸。
二、18650鋰電池使用時要注意什么
前(qian)文已經簡單了解了18650鋰(li)電池的(de)耐溫度數,接著(zhu)就來(lai)看看18650鋰(li)電池使用(yong)時要注(zhu)意什么(me)?
1、先充電,避免電池過度充電
第一次充(chong)(chong)(chong)(chong)電(dian)(dian)時(shi)(shi),選擇(ze)白天(tian)充(chong)(chong)(chong)(chong)電(dian)(dian)。夜間充(chong)(chong)(chong)(chong)電(dian)(dian)時(shi)(shi)容(rong)易發生過(guo)充(chong)(chong)(chong)(chong),損壞電(dian)(dian)池。而且白天(tian)充(chong)(chong)(chong)(chong)電(dian)(dian)的(de)時(shi)(shi)候很(hen)容(rong)易控制(zhi)充(chong)(chong)(chong)(chong)電(dian)(dian)時(shi)(shi)間,充(chong)(chong)(chong)(chong)電(dian)(dian)的(de)時(shi)(shi)候要(yao)注意時(shi)(shi)間。
2、充電時間
最好選擇白天的充電器,盡(jin)量不要(yao)給18650鋰電(dian)(dian)池充(chong)電(dian)(dian)一晚上,注(zhu)意充(chong)電(dian)(dian)器(qi)的(de)時(shi)間,這樣(yang)有時(shi)間處理危(wei)險(xian)的(de)時(shi)候。
3、避免過充
充(chong)電器的時(shi)間要(yao)控(kong)制好(hao),最好(hao)不要(yao)超過(guo)8小(xiao)時(shi)。過(guo)度(du)充(chong)電會縮短18650鋰電池(chi)的壽命,也可(ke)能導致(zhi)負電壓過(guo)大。
