常用電池的類型有哪些
1、干電池
干(gan)電(dian)(dian)(dian)(dian)(dian)池(chi)也叫錳鋅電(dian)(dian)(dian)(dian)(dian)池(chi),所謂干(gan)電(dian)(dian)(dian)(dian)(dian)池(chi)是(shi)相(xiang)對于伏打電(dian)(dian)(dian)(dian)(dian)池(chi)而(er)言(yan),所謂錳鋅是(shi)指其原材料(liao)。針(zhen)對其它材料(liao)的(de)(de)干(gan)電(dian)(dian)(dian)(dian)(dian)池(chi)如氧(yang)化銀電(dian)(dian)(dian)(dian)(dian)池(chi),鎳鎘電(dian)(dian)(dian)(dian)(dian)池(chi)而(er)言(yan)。錳鋅電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓是(shi)15V。干(gan)電(dian)(dian)(dian)(dian)(dian)池(chi)是(shi)消(xiao)耗化學原料(liao)產生電(dian)(dian)(dian)(dian)(dian)能的(de)(de),它的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓不高,所能產生的(de)(de)持(chi)續電(dian)(dian)(dian)(dian)(dian)流不能超過1安培(pei),因此它在一些(xie)小電(dian)(dian)(dian)(dian)(dian)器(qi)中使(shi)用率較(jiao)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于數碼設(she)備。
3、鋰電池
鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)是(shi)指以鋰(li)(li)為(wei)負極的電(dian)(dian)(dian)池(chi)(chi)(chi)。按(an)所用電(dian)(dian)(dian)解質(zhi)不同分為(wei)高溫熔融鹽鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)、有機電(dian)(dian)(dian)解質(zhi)鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)、無機非水(shui)電(dian)(dian)(dian)解質(zhi)鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)、固體(ti)電(dian)(dian)(dian)解質(zhi)鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)、鋰(li)(li)水(shui)電(dian)(dian)(dian)池(chi)(chi)(chi)這幾種類型。鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)的優點是(shi)單體(ti)電(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)壓高,比能量大,儲存壽命長(可達10年),高低溫性(xing)(xing)能好,可在-40~150℃使(shi)用。缺點是(shi)價格昂貴,安全性(xing)(xing)不高。另外電(dian)(dian)(dian)壓滯后(hou)和安全問題尚待改(gai)善。
廢電池有什么危害
廢(fei)舊電(dian)池中的(de)金(jin)屬汞(gong)能(neng)溶(rong)解于脂肪,引(yin)發動物(wu)中樞神經疾病,致(zhi)畸、致(zhi)變(bian)、致(zhi)癌甚至死亡。鎘使骨質(zhi)軟(ruan)化、骨骼變(bian)形(xing),嚴重時形(xing)成自然骨折,以致(zhi)死亡。鋅的(de)鹽類使蛋白(bai)質(zhi)沉淀,對皮膚(fu)黏膜有刺激作用。鉛(qian)主要是導致(zhi)貧血(xue)、神經功能(neng)失調和(he)腎損傷(shang),抑制血(xue)紅蛋白(bai)的(de)合成代謝。鎳溶(rong)解于血(xue)液,會引(yin)起(qi)血(xue)管變(bian)異(yi)。錳(meng)會引(yin)起(qi)神經性功能(neng)障礙,綜合性功能(neng)紊亂,較重者出現精神癥狀(zhuang)。
