　　鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)分為(wei)鋰(li)(li)離(li)子電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)和鋰(li)(li)聚合(he)(he)物電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。鋰(li)(li)離(li)子電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)解質(zhi)是(shi)流動的(de)，因(yin)此，比鋰(li)(li)聚合(he)(he)物電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)更不穩定(ding)，碰(peng)到外力摔打，或者使用不符合(he)(he)標準的(de)充電(dian)(dian)(dian)(dian)(dian)(dian)器，都(dou)可(ke)能引起電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)爆炸(zha)。很多(duo)手機、手提電(dian)(dian)(dian)(dian)(dian)(dian)腦等便攜式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)子產品，所(suo)用的(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)都(dou)是(shi)鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。也就是(shi)說，很多(duo)人的(de)身邊有一個“危險(xian)品”。為(wei)安全起見，選購時你一定(ding)要(yao)注(zhu)意以下幾點。

　　一、有(you)沒有(you)標示明確容量(liang)。無(wu)明確標示容量(liang)（如1000mAh或1000毫安培小時）的(de)電池很有(you)可(ke)(ke)能就是(shi)使用(yong)(yong)劣(lie)質電池或回(hui)收(shou)電池。市場上充斥的(de)許多廉價的(de)電池，就是(shi)使用(yong)(yong)回(hui)收(shou)電池心做的(de)，價格雖然便宜，但是(shi)壽命短、品(pin)質不穩(wen)定，使用(yong)(yong)不慎可(ke)(ke)能會(hui)損(sun)壞手機。

　　二、有(you)沒(mei)有(you)保證待(dai)機(ji)時間(jian)。待(dai)機(ji)時間(jian)即電池裝(zhuang)入手機(ji)后(hou)到下(xia)一(yi)次充電的(de)(de)連續使用時間(jian)。一(yi)般(ban)市場上銷售的(de)(de)電池都無法對顧客保證待(dai)機(ji)時間(jian)，這是因為電池品(pin)質不穩(wen)定的(de)(de)關系，許多廉價的(de)(de)電池因為是使用品(pin)質不良的(de)(de)電池心，所以(yi)待(dai)機(ji)時間(jian)很短(duan)。

　　三(san)、是(shi)(shi)否(fou)加裝安全保(bao)護電路(lu)板(ban)(ban)。無保(bao)護電路(lu)板(ban)(ban)，則鋰電池就有變形、漏液、爆(bao)炸的危險(xian)。在惡性削價競爭下，各家(jia)尋求更(geng)低價位的保(bao)護電路(lu)板(ban)(ban)，或者(zhe)根本省略了這(zhe)個裝置，使得市(shi)面上充斥著有爆(bao)炸危險(xian)的鋰電池。消費(fei)者(zhe)無法從外觀(guan)分(fen)辨出來(lai)是(shi)(shi)否(fou)有保(bao)護電路(lu)板(ban)(ban)，因此最好選擇有信譽的商家(jia)購買。
