常用電池的類型有哪些
1、干電池
干電(dian)(dian)(dian)池也叫錳鋅(xin)電(dian)(dian)(dian)池,所(suo)(suo)謂干電(dian)(dian)(dian)池是相對于伏打電(dian)(dian)(dian)池而(er)言(yan),所(suo)(suo)謂錳鋅(xin)是指其(qi)原材料(liao)。針對其(qi)它材料(liao)的(de)干電(dian)(dian)(dian)池如氧(yang)化銀(yin)電(dian)(dian)(dian)池,鎳(nie)鎘電(dian)(dian)(dian)池而(er)言(yan)。錳鋅(xin)電(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)壓是15V。干電(dian)(dian)(dian)池是消耗化學(xue)原料(liao)產生電(dian)(dian)(dian)能的(de),它的(de)電(dian)(dian)(dian)壓不高,所(suo)(suo)能產生的(de)持續電(dian)(dian)(dian)流(liu)不能超過1安培,因此它在一些小電(dian)(dian)(dian)器中(zhong)使用(yong)率(lv)較高。
2、蓄電池
蓄電池是應用最廣泛的電池之一,它的正負極之間有2伏的電壓。蓄電池的好處是可以反復多次使用,不斷進行充放電。另外,由于它的內阻極小,所以可以提供很大的電流。用它給汽車的發動機供電,瞬時電流可達20多安培。蓄電池充電時能將電能貯存起來,放電時又把化學能轉化為電能。但是蓄電池存在記憶效應,在充放電過程中如果處理不當,會使得其服務壽命大大縮短,這個缺點導致這類電池品牌產品不能用(yong)于(yu)數碼設備。
3、鋰電池
鋰電(dian)(dian)(dian)池(chi)(chi)是(shi)指以鋰為負(fu)極的電(dian)(dian)(dian)池(chi)(chi)。按所用電(dian)(dian)(dian)解質(zhi)(zhi)不(bu)同分為高(gao)(gao)溫(wen)熔融鹽鋰電(dian)(dian)(dian)池(chi)(chi)、有機(ji)電(dian)(dian)(dian)解質(zhi)(zhi)鋰電(dian)(dian)(dian)池(chi)(chi)、無機(ji)非(fei)水電(dian)(dian)(dian)解質(zhi)(zhi)鋰電(dian)(dian)(dian)池(chi)(chi)、固體電(dian)(dian)(dian)解質(zhi)(zhi)鋰電(dian)(dian)(dian)池(chi)(chi)、鋰水電(dian)(dian)(dian)池(chi)(chi)這幾種(zhong)類型。鋰電(dian)(dian)(dian)池(chi)(chi)的優點(dian)是(shi)單體電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)壓高(gao)(gao),比能(neng)量大,儲存壽命長(可達10年(nian)),高(gao)(gao)低溫(wen)性(xing)能(neng)好,可在-40~150℃使用。缺點(dian)是(shi)價格昂貴,安(an)全(quan)性(xing)不(bu)高(gao)(gao)。另(ling)外(wai)電(dian)(dian)(dian)壓滯后和安(an)全(quan)問題尚待改善。
廢電池有什么危害
廢(fei)舊(jiu)電池中的(de)金屬汞能溶(rong)(rong)解于(yu)脂肪(fang),引(yin)發動(dong)物中樞神(shen)經(jing)疾(ji)病(bing),致(zhi)畸、致(zhi)變(bian)、致(zhi)癌甚至死亡。鎘使(shi)骨質軟化、骨骼變(bian)形,嚴重(zhong)時形成自然骨折(zhe),以致(zhi)死亡。鋅的(de)鹽類使(shi)蛋白(bai)質沉淀(dian),對皮膚黏膜有刺激作用。鉛主要是導致(zhi)貧(pin)血(xue)、神(shen)經(jing)功能失調和腎(shen)損(sun)傷,抑制(zhi)血(xue)紅蛋白(bai)的(de)合成代謝。鎳溶(rong)(rong)解于(yu)血(xue)液,會引(yin)起血(xue)管(guan)變(bian)異(yi)。錳(meng)會引(yin)起神(shen)經(jing)性功能障(zhang)礙,綜合性功能紊亂,較(jiao)重(zhong)者出現精(jing)神(shen)癥狀。
