一、堿性干電池和碳性干電池有什么區別
干電池按照電解質性質不同,可分為堿性和碳性兩種,它們雖然都是干電池,但在很多方面有(you)所不同,堿(jian)性(xing)干電(dian)池(chi)和碳性(xing)干電(dian)池(chi)的區(qu)別主要(yao)有(you):
1、結構原理不同
碳(tan)性(xing)干電池和(he)堿性(xing)干電池的結(jie)構和(he)原理都是(shi)(shi)基于鋅-錳體系(xi),但是(shi)(shi)有(you)一(yi)些不同之(zhi)處。碳(tan)性(xing)干電池的正極是(shi)(shi)由(you)二氧化錳和(he)石墨組成的炭(tan)棒,負極是(shi)(shi)由(you)鋅皮制(zhi)成的外(wai)殼,電解質是(shi)(shi)含有(you)氯(lv)化銨和(he)氯(lv)化鋅的水(shui)溶(rong)液。
堿(jian)性(xing)干(gan)電(dian)(dian)池(chi)的(de)正極(ji)(ji)是由(you)(you)二氧(yang)化(hua)(hua)錳和碳粉(fen)組成的(de)環形極(ji)(ji)片,負極(ji)(ji)是由(you)(you)鋅(xin)粉(fen)和添加劑制成的(de)鋅(xin)膏,電(dian)(dian)解(jie)質(zhi)是含(han)有(you)氫(qing)氧(yang)化(hua)(hua)鉀的(de)水溶液。碳性(xing)干(gan)電(dian)(dian)池(chi)和堿(jian)性(xing)干(gan)電(dian)(dian)池(chi)的(de)放電(dian)(dian)反應都是鋅(xin)和二氧(yang)化(hua)(hua)錳在電(dian)(dian)解(jie)質(zhi)中發生(sheng)氧(yang)化(hua)(hua)還原反應,產生(sheng)電(dian)(dian)流(liu)和電(dian)(dian)壓。
2、電池容量不同
碳(tan)性(xing)(xing)(xing)干電(dian)(dian)池(chi)(chi)(chi)和堿(jian)(jian)性(xing)(xing)(xing)干電(dian)(dian)池(chi)(chi)(chi)的(de)輸出電(dian)(dian)壓(ya)都是(shi)1.5伏,但是(shi)它們的(de)容(rong)量(liang)卻有(you)很大的(de)差(cha)別,堿(jian)(jian)性(xing)(xing)(xing)干電(dian)(dian)池(chi)(chi)(chi)的(de)容(rong)量(liang)是(shi)碳(tan)性(xing)(xing)(xing)干電(dian)(dian)池(chi)(chi)(chi)的(de)4-7倍,這意味著堿(jian)(jian)性(xing)(xing)(xing)干電(dian)(dian)池(chi)(chi)(chi)可(ke)以持續使(shi)用的(de)時(shi)間更長,或者可(ke)以為更大功率的(de)電(dian)(dian)器提供電(dian)(dian)能。堿(jian)(jian)性(xing)(xing)(xing)干電(dian)(dian)池(chi)(chi)(chi)的(de)容(rong)量(liang)會隨(sui)著放(fang)電(dian)(dian)電(dian)(dian)流的(de)增加(jia)而減(jian)小,但是(shi)仍然高于碳(tan)性(xing)(xing)(xing)干電(dian)(dian)池(chi)(chi)(chi)。
3、重量不同
由于堿性(xing)(xing)干電(dian)池(chi)的內部材料和結構比(bi)碳性(xing)(xing)干電(dian)池(chi)更復(fu)雜(za),堿性(xing)(xing)干電(dian)池(chi)的重量一般比(bi)碳性(xing)(xing)干電(dian)池(chi)重。
4、價格不同
堿性(xing)干(gan)(gan)電(dian)(dian)(dian)池的價格也比碳性(xing)干(gan)(gan)電(dian)(dian)(dian)池高,一(yi)般(ban)是碳性(xing)干(gan)(gan)電(dian)(dian)(dian)池的1.5-2倍,不過(guo)堿性(xing)干(gan)(gan)電(dian)(dian)(dian)池的使用壽命通常要更(geng)長一(yi)些(xie),性(xing)價比還是比較高的。
5、適用范圍不同
碳性(xing)干(gan)電(dian)(dian)池適合用于低(di)電(dian)(dian)流(liu)和低(di)功率的(de)(de)電(dian)(dian)器(qi),如手電(dian)(dian)筒(tong)、收音機(ji)、遙控(kong)器(qi)、鐘表等。這些電(dian)(dian)器(qi)的(de)(de)特(te)點(dian)是用電(dian)(dian)量小,對電(dian)(dian)池的(de)(de)性(xing)能要求(qiu)不(bu)高(gao),使(shi)用碳性(xing)干(gan)電(dian)(dian)池可以滿足基本的(de)(de)需求(qiu)。
堿性(xing)干(gan)電(dian)池(chi)適合用(yong)于(yu)高(gao)電(dian)流和(he)(he)高(gao)功率的電(dian)器(qi),如數碼相(xiang)機、閃光燈、電(dian)動玩具、剃須刀、無(wu)線鼠標等。這些電(dian)器(qi)的特點是用(yong)電(dian)量大,對電(dian)池(chi)的性(xing)能要求高(gao),使用(yong)堿性(xing)干(gan)電(dian)池(chi)可(ke)以(yi)保證電(dian)器(qi)的正常工(gong)作和(he)(he)良好(hao)的性(xing)能。
6、保質期和自放電不同
保質期是(shi)(shi)指電(dian)池(chi)在(zai)未(wei)使用的(de)(de)情況下,能夠保持一定的(de)(de)電(dian)量(liang)和性能的(de)(de)時間(jian)。自放電(dian)是(shi)(shi)指電(dian)池(chi)在(zai)未(wei)使用的(de)(de)情況下,由于(yu)內部化學反應而逐(zhu)漸損(sun)失電(dian)量(liang)的(de)(de)現象。
一(yi)般來說,堿性(xing)干(gan)(gan)(gan)電(dian)(dian)池的(de)保(bao)(bao)質期(qi)要遠遠超過碳(tan)性(xing)干(gan)(gan)(gan)電(dian)(dian)池的(de)保(bao)(bao)質期(qi)。碳(tan)性(xing)干(gan)(gan)(gan)電(dian)(dian)池的(de)保(bao)(bao)質期(qi)一(yi)般為(wei)1-2年(nian)(nian)(nian),而堿性(xing)干(gan)(gan)(gan)電(dian)(dian)池的(de)保(bao)(bao)質期(qi)一(yi)般為(wei)5-10年(nian)(nian)(nian),甚至更(geng)長。堿性(xing)干(gan)(gan)(gan)電(dian)(dian)池的(de)自放(fang)電(dian)(dian)也比碳(tan)性(xing)干(gan)(gan)(gan)電(dian)(dian)池低,一(yi)般為(wei)每年(nian)(nian)(nian)2-3%,而碳(tan)性(xing)干(gan)(gan)(gan)電(dian)(dian)池的(de)自放(fang)電(dian)(dian)一(yi)般為(wei)每年(nian)(nian)(nian)10-15%。這意味著(zhu)堿性(xing)干(gan)(gan)(gan)電(dian)(dian)池可以更(geng)長時間(jian)地保(bao)(bao)存(cun)和(he)使(shi)用,不會因為(wei)時間(jian)過長而失效。
7、環保性不同
碳性干電池中含(han)有重金屬鎘(ge)和水銀,這些物質(zhi)對(dui)人體(ti)和環境都有危害,如果不經過回收處(chu)理,就直(zhi)接丟棄,會污染土壤和水源(yuan),影響生態平衡。堿(jian)性干電池中不含(han)重金屬鎘(ge)和水銀,相對(dui)來說要環保一(yi)些。
二、堿性干電池和碳性干電池哪個好
堿性干(gan)電池和碳(tan)性干(gan)電池對(dui)比(bi)起來,在很(hen)多方面(mian)都有所區(qu)別(bie),不過并不一定(ding)堿性干(gan)電池就更(geng)好(hao)(hao),或者碳(tan)性干(gan)電池更(geng)好(hao)(hao),要根據(ju)設(she)備功(gong)率需求、使用時(shi)間和環(huan)境考(kao)慮(lv)選擇(ze):
一般來說(shuo),堿性(xing)干電(dian)池通常具有更高的(de)能量(liang)密度和較(jiao)長的(de)壽命(ming),適合(he)高耗能設備;而碳性(xing)干電(dian)池價格便宜,適用于低功率設備。
三、堿性干電池和碳性干電池可以共用嗎
堿性干電池和(he)碳性干電池(chi)很(hen)多(duo)在外表上并沒有(you)多(duo)大(da)區(qu)別,有(you)用(yong)(yong)戶可能會(hui)混用(yong)(yong),不過一般這兩種干電池(chi)是不建議(yi)共用(yong)(yong)的。
由(you)于堿性(xing)干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)和碳(tan)性(xing)干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)正極、負(fu)極及電(dian)(dian)(dian)(dian)解質均不(bu)同,因(yin)此(ci)他們的(de)操(cao)作電(dian)(dian)(dian)(dian)壓和儲電(dian)(dian)(dian)(dian)量(liang)都有所不(bu)同,一般(ban)(ban)來說,堿性(xing)干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)容量(liang)是碳(tan)性(xing)干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)五到六倍,而電(dian)(dian)(dian)(dian)流也(ye)比碳(tan)性(xing)干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)要大,混用的(de)話可能(neng)影響供電(dian)(dian)(dian)(dian);而且碳(tan)性(xing)干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)會更(geng)早用完,頻繁(fan)更(geng)換也(ye)麻煩,因(yin)此(ci)一般(ban)(ban)建議(yi)不(bu)要混用。
