事態回顧

在(zai)(zai)美(mei)國銷售(shou)了近百萬部Note7智能手(shou)(shou)機(ji)(ji)。佛羅(luo)里達州(zhou)棕(zong)櫚(lv)灘縣的(de)居民喬納森·斯特羅(luo)貝爾聲稱他(ta)的(de)Note7在(zai)(zai)他(ta)9月(yue)9日的(de)右口袋里發(fa)生(sheng)爆炸，導致(zhi)他(ta)的(de)腿嚴重(zhong)燒傷(shang)(shang)，使他(ta)處于(yu)(yu)休克和(he)極度疼(teng)痛之中(zhong)(zhong)。三星已(yi)經(jing)收到92起關于(yu)(yu)美(mei)國電池(chi)(chi)過熱的(de)報告(gao)(gao)，包(bao)括26起燒傷(shang)(shang)報告(gao)(gao)和(he)55起財產損失報告(gao)(gao)，包(bao)括汽車和(he)車庫火(huo)災。三家(jia)澳大利亞航(hang)空(kong)公(gong)司禁止(zhi)乘客(ke)在(zai)(zai)航(hang)班期間使用三星電子的(de)Galaxy Note 7智能手(shou)(shou)機(ji)(ji)，原因是擔心這(zhe)款(kuan)手(shou)(shou)機(ji)(ji)易受火(huo)災影響。三星Note7手(shou)(shou)機(ji)(ji)電池(chi)(chi)就(jiu)像大多數(shu)手(shou)(shou)機(ji)(ji)電池(chi)(chi)都(dou)是鋰(li)(li)電池(chi)(chi)，鋰(li)(li)離子電池(chi)(chi)在(zai)(zai)我們(men)的(de)日常生(sheng)活中(zhong)(zhong)使用越來越廣泛，比如我們(men)的(de)無人機(ji)(ji)電池(chi)(chi)都(dou)是鋰(li)(li)電池(chi)(chi)，所以學(xue)習如何使用和(he)維護(hu)無人機(ji)(ji)鋰(li)(li)離子電池(chi)(chi)非常重(zhong)要。

為什(shen)么(me)鋰電(dian)池會爆(bao)炸？

鋰(li)(li)離(li)(li)(li)子(zi)(zi)(zi)電池(chi)在(zai)性(xing)能上優(you)于鉛酸電池(chi)，鎳鎘電池(chi)，鎳氫電池(chi)，在(zai)放電時間(jian)優(you)于燃料(liao)電池(chi)。但鋰(li)(li)離(li)(li)(li)子(zi)(zi)(zi)電池(chi)的安(an)全性(xing)仍(reng)有待(dai)提高。鋰(li)(li)離(li)(li)(li)子(zi)(zi)(zi)電池(chi)最大的危(wei)害是如(ru)果過(guo)充電鋰(li)(li)離(li)(li)(li)子(zi)(zi)(zi)陽極在(zai)枝晶中形成并(bing)刺穿隔膜，形成內部(bu)短(duan)路。外(wai)部(bu)短(duan)路，內部(bu)短(duan)路會產生數百(bai)安(an)培(pei)的電流，導致電池(chi)爆(bao)炸過(guo)熱。

如(ru)何使(shi)用(yong)鋰(li)離(li)子電池？
