常用電池的類型有哪些
1、干電池
干(gan)(gan)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)也(ye)叫錳(meng)鋅(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi),所(suo)謂干(gan)(gan)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)是(shi)相對于伏打電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)而(er)言(yan),所(suo)謂錳(meng)鋅(xin)(xin)是(shi)指(zhi)其(qi)原材料(liao)。針對其(qi)它材料(liao)的干(gan)(gan)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)如氧化銀(yin)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi),鎳鎘電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)而(er)言(yan)。錳(meng)鋅(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的電(dian)(dian)(dian)(dian)(dian)(dian)壓是(shi)15V。干(gan)(gan)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)是(shi)消耗化學原料(liao)產生電(dian)(dian)(dian)(dian)(dian)(dian)能的,它的電(dian)(dian)(dian)(dian)(dian)(dian)壓不高,所(suo)能產生的持續(xu)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)不能超過1安培,因此(ci)它在一些小電(dian)(dian)(dian)(dian)(dian)(dian)器中使用(yong)率較高。
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)于數(shu)碼設(she)備。
3、鋰電池
鋰(li)電(dian)(dian)池(chi)是(shi)指以鋰(li)為(wei)負極的(de)電(dian)(dian)池(chi)。按所用電(dian)(dian)解質不同分為(wei)高(gao)(gao)溫(wen)熔融鹽鋰(li)電(dian)(dian)池(chi)、有(you)機電(dian)(dian)解質鋰(li)電(dian)(dian)池(chi)、無(wu)機非水電(dian)(dian)解質鋰(li)電(dian)(dian)池(chi)、固體電(dian)(dian)解質鋰(li)電(dian)(dian)池(chi)、鋰(li)水電(dian)(dian)池(chi)這幾種(zhong)類型。鋰(li)電(dian)(dian)池(chi)的(de)優(you)點是(shi)單體電(dian)(dian)池(chi)電(dian)(dian)壓(ya)高(gao)(gao),比能量大,儲存壽命長(chang)(可(ke)達10年),高(gao)(gao)低(di)溫(wen)性能好,可(ke)在(zai)-40~150℃使用。缺點是(shi)價(jia)格昂(ang)貴,安(an)全性不高(gao)(gao)。另外電(dian)(dian)壓(ya)滯后和安(an)全問題尚待(dai)改善。
廢電池有什么危害
廢(fei)舊電(dian)池中的金(jin)屬汞(gong)能(neng)溶解于(yu)脂肪(fang),引(yin)發動(dong)物(wu)中樞神(shen)經疾(ji)病,致畸(ji)、致變、致癌甚(shen)至(zhi)死(si)亡(wang)。鎘使骨質(zhi)軟化、骨骼(ge)變形,嚴重(zhong)時形成自然骨折,以(yi)致死(si)亡(wang)。鋅的鹽類使蛋(dan)白質(zhi)沉淀,對皮膚黏膜(mo)有刺激作用。鉛主要是導致貧血(xue)(xue)、神(shen)經功能(neng)失調和腎損傷,抑(yi)制(zhi)血(xue)(xue)紅(hong)蛋(dan)白的合成代謝。鎳(nie)溶解于(yu)血(xue)(xue)液,會(hui)引(yin)起血(xue)(xue)管變異。錳會(hui)引(yin)起神(shen)經性功能(neng)障礙,綜(zong)合性功能(neng)紊亂,較重(zhong)者出(chu)現精(jing)神(shen)癥狀(zhuang)。
