一、干電池和鋰電池的區別在哪里
電池作為供電裝置,其種類眾多,干電池和鋰電池是常見的兩種,像遙控器、鬧鐘等家用小電器里的電池就是干電池,而鋰(li)電(dian)池則(ze)多用于手機(ji)、數碼相(xiang)機(ji)等,這兩種電(dian)池之間(jian)的區別主要(yao)有:
1、干電(dian)(dian)池的(de)(de)電(dian)(dian)壓(ya)是固(gu)定的(de)(de),通常(chang)為(wei)1.5伏(fu)特;而(er)鋰電(dian)(dian)池的(de)(de)電(dian)(dian)壓(ya)則根據其材(cai)料和工藝的(de)(de)不同而(er)有所差異,通常(chang)在3.0-4.5伏(fu)特之間。
2、干電(dian)(dian)池是一(yi)次性電(dian)(dian)池,電(dian)(dian)量(liang)用(yong)(yong)完后不能充電(dian)(dian);鋰(li)電(dian)(dian)池是可充電(dian)(dian)的電(dian)(dian)池,使用(yong)(yong)壽(shou)命更長。
3、電(dian)池(chi)容(rong)量(liang)方面,干電(dian)池(chi)型號不同,儲電(dian)容(rong)量(liang)也有所不同,但整體來說不如鋰(li)電(dian)池(chi),鋰(li)電(dian)池(chi)屬于新型儲能技術,容(rong)量(liang)更大,也更輕更薄(bo)。
4、環(huan)保(bao)性方面,現(xian)在的干(gan)電池(chi)(chi)已經是無(wu)汞(gong)或(huo)低汞(gong)的了(le),不過(guo)仍含(han)有部分重金屬(shu);鋰電池(chi)(chi)相對(dui)來說(shuo)要更環(huan)保(bao)一些(xie)。
5、應用(yong)方面,干電(dian)(dian)(dian)池因(yin)其(qi)低廉的價格和較(jiao)穩定的性能被(bei)廣(guang)泛(fan)應用(yong)于(yu)各種(zhong)領域,如(ru)遙(yao)控(kong)器、鐘表(biao)、手(shou)電(dian)(dian)(dian)筒等(deng)。而鋰電(dian)(dian)(dian)池則因(yin)其(qi)高能量密度和高性能等(deng)特點被(bei)廣(guang)泛(fan)應用(yong)于(yu)移動(dong)電(dian)(dian)(dian)子設備、電(dian)(dian)(dian)動(dong)汽車等(deng)領域。
二、干電池和鋰電池哪個好
干電池(chi)和鋰電池(chi)對比(bi)起來,各(ge)有各(ge)的優缺點,哪個好并不(bu)能一(yi)(yi)概而論,要根(gen)據應用需要來選(xuan)擇,下面為大家對比(bi)一(yi)(yi)下:
1、干電池的優缺點點
(1)優(you)點(dian):干電(dian)池(chi)制造成(cheng)本低,因此價格較便宜,安全(quan)性方面干電(dian)池(chi)表現(xian)也更(geng)好。
(2)缺點(dian):干(gan)(gan)電(dian)(dian)(dian)池(chi)通常只能使用(yong)一(yi)次,壽命較短(duan),一(yi)旦電(dian)(dian)(dian)池(chi)沒電(dian)(dian)(dian)就需要更換;另外,干(gan)(gan)電(dian)(dian)(dian)池(chi)儲存時間長(chang)會(hui)自己耗電(dian)(dian)(dian)。
2、鋰電池的優缺點
(1)優點:鋰(li)(li)電(dian)(dian)池(chi)(chi)(chi)具有長壽命(ming),可在一定(ding)程度(du)上減少(shao)更換電(dian)(dian)池(chi)(chi)(chi)的頻率;鋰(li)(li)電(dian)(dian)池(chi)(chi)(chi)相(xiang)比干(gan)電(dian)(dian)池(chi)(chi)(chi)更安全,因為它們不會泄(xie)漏(lou)和產生氣體,而(er)且(qie)鋰(li)(li)電(dian)(dian)池(chi)(chi)(chi)內部的化(hua)學反應會自行停止;鋰(li)(li)電(dian)(dian)池(chi)(chi)(chi)比干(gan)電(dian)(dian)池(chi)(chi)(chi)能容納更高的電(dian)(dian)量(liang)。
(2)缺點(dian):鋰電(dian)池(chi)在(zai)過充電(dian)時易發生化學(xue)反應,可能導致電(dian)池(chi)脹氣、漏液、甚至爆炸;鋰電(dian)池(chi)的制造(zao)成本相對較(jiao)高;鋰電(dian)池(chi)的低溫性能不佳。
三、干電池和鋰電池哪個安全
干電池更安全。
干(gan)電池采(cai)用(yong)非可充電的化學反應(ying),相對較穩定且不容易引發(fa)嚴重的安(an)(an)全(quan)問(wen)題(ti)。而鋰電池具(ju)有較高(gao)的能量密度,雖然(ran)在(zai)(zai)正常使用(yong)情況下(xia)是相對安(an)(an)全(quan)的,但過度充電、損壞或高(gao)溫等(deng)極端條件(jian)下(xia)存在(zai)(zai)熱失控、起火或爆炸的風險(xian)。
