常用電池的類型有哪些
1、干電池
干(gan)電(dian)(dian)(dian)池(chi)(chi)也叫錳(meng)鋅(xin)電(dian)(dian)(dian)池(chi)(chi),所(suo)謂干(gan)電(dian)(dian)(dian)池(chi)(chi)是(shi)(shi)相(xiang)對于伏打電(dian)(dian)(dian)池(chi)(chi)而(er)言,所(suo)謂錳(meng)鋅(xin)是(shi)(shi)指其原(yuan)材料(liao)。針(zhen)對其它(ta)材料(liao)的干(gan)電(dian)(dian)(dian)池(chi)(chi)如氧(yang)化銀電(dian)(dian)(dian)池(chi)(chi),鎳鎘電(dian)(dian)(dian)池(chi)(chi)而(er)言。錳(meng)鋅(xin)電(dian)(dian)(dian)池(chi)(chi)的電(dian)(dian)(dian)壓(ya)是(shi)(shi)15V。干(gan)電(dian)(dian)(dian)池(chi)(chi)是(shi)(shi)消(xiao)耗化學原(yuan)料(liao)產生電(dian)(dian)(dian)能(neng)的,它(ta)的電(dian)(dian)(dian)壓(ya)不(bu)高(gao),所(suo)能(neng)產生的持(chi)續電(dian)(dian)(dian)流(liu)不(bu)能(neng)超過1安培,因此它(ta)在一些小電(dian)(dian)(dian)器中使用率較高(gao)。
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于數碼設備。
3、鋰電池
鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是指(zhi)以(yi)鋰(li)(li)為負極的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。按所用電(dian)(dian)(dian)(dian)解(jie)質不同(tong)分為高溫(wen)熔融鹽(yan)鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)、有機電(dian)(dian)(dian)(dian)解(jie)質鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)、無(wu)機非水(shui)電(dian)(dian)(dian)(dian)解(jie)質鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)、固體(ti)電(dian)(dian)(dian)(dian)解(jie)質鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)、鋰(li)(li)水(shui)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)這幾種類型。鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)優點是單體(ti)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)壓(ya)高,比能(neng)(neng)量大,儲存壽(shou)命長(可達10年),高低溫(wen)性(xing)能(neng)(neng)好,可在-40~150℃使(shi)用。缺(que)點是價格昂貴,安全性(xing)不高。另(ling)外(wai)電(dian)(dian)(dian)(dian)壓(ya)滯后和安全問題尚待改善(shan)。
廢電池有什么危害
廢(fei)舊(jiu)電池中的金屬汞(gong)能(neng)溶(rong)解(jie)于脂肪,引(yin)發動物中樞神經疾(ji)病,致(zhi)(zhi)畸(ji)、致(zhi)(zhi)變(bian)(bian)、致(zhi)(zhi)癌(ai)甚(shen)至死亡(wang)。鎘使骨質軟化、骨骼變(bian)(bian)形(xing),嚴重(zhong)(zhong)時形(xing)成自然骨折,以致(zhi)(zhi)死亡(wang)。鋅的鹽類使蛋白(bai)質沉淀(dian),對(dui)皮膚(fu)黏(nian)膜(mo)有刺激作用。鉛(qian)主要(yao)是導致(zhi)(zhi)貧血、神經功能(neng)失調和腎損傷,抑制血紅蛋白(bai)的合成代謝(xie)。鎳溶(rong)解(jie)于血液,會引(yin)起血管變(bian)(bian)異。錳(meng)會引(yin)起神經性功能(neng)障(zhang)礙(ai),綜合性功能(neng)紊亂,較重(zhong)(zhong)者出現精神癥狀。
