電池行業簡介

電池型號尺寸一般是多少

電(dian)(dian)池型(xing)號(hao)(hao)尺寸有(you)很多，包(bao)括一(yi)(yi)號(hao)(hao)二號(hao)(hao)五號(hao)(hao)七號(hao)(hao)等等，其中(zhong)5號(hao)(hao)電(dian)(dian)池和7號(hao)(hao)電(dian)(dian)池是生活中(zhong)最常見的兩種電(dian)(dian)池。5號(hao)(hao)電(dian)(dian)池高49.0，直徑14.0，一(yi)(yi)般用(yong)于電(dian)(dian)子玩具或數碼設備。7號(hao)(hao)電(dian)(dian)池高44.0，直徑10.0，一(yi)(yi)般用(yong)戶遙控器。

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)(chi)也叫錳鋅(xin)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，所(suo)(suo)謂干(gan)(gan)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)相(xiang)對(dui)于伏打(da)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)而言，所(suo)(suo)謂錳鋅(xin)是(shi)指(zhi)其原材料(liao)。針對(dui)其它材料(liao)的干(gan)(gan)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)如氧化銀電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，鎳鎘電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)而言。錳鋅(xin)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)是(shi)15V。干(gan)(gan)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)消(xiao)耗化學原料(liao)產(chan)生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)的，它的電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)不高(gao)，所(suo)(suo)能(neng)產(chan)生(sheng)的持續電(dian)(dian)(dian)(dian)(dian)(dian)流不能(neng)超(chao)過1安培(pei)，因(yin)此(ci)它在一些小電(dian)(dian)(dian)(dian)(dian)(dian)器中使用率較(jiao)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(neng)用于數碼設備(bei)。

3、鋰電池

鋰電(dian)(dian)(dian)池(chi)(chi)(chi)是指(zhi)以鋰為負極(ji)的電(dian)(dian)(dian)池(chi)(chi)(chi)。按所(suo)用電(dian)(dian)(dian)解(jie)質不(bu)同分為高(gao)(gao)(gao)溫(wen)熔融鹽鋰電(dian)(dian)(dian)池(chi)(chi)(chi)、有機電(dian)(dian)(dian)解(jie)質鋰電(dian)(dian)(dian)池(chi)(chi)(chi)、無機非水電(dian)(dian)(dian)解(jie)質鋰電(dian)(dian)(dian)池(chi)(chi)(chi)、固體電(dian)(dian)(dian)解(jie)質鋰電(dian)(dian)(dian)池(chi)(chi)(chi)、鋰水電(dian)(dian)(dian)池(chi)(chi)(chi)這幾(ji)種類(lei)型。鋰電(dian)(dian)(dian)池(chi)(chi)(chi)的優點是單體電(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)壓(ya)高(gao)(gao)(gao)，比能量大(da)，儲存(cun)壽命長（可(ke)達10年），高(gao)(gao)(gao)低(di)溫(wen)性能好，可(ke)在-40～150℃使(shi)用。缺點是價格昂貴，安全性不(bu)高(gao)(gao)(gao)。另外電(dian)(dian)(dian)壓(ya)滯后和安全問題尚(shang)待改善。

廢電池有什么危害

廢舊(jiu)電池(chi)中的(de)金屬汞(gong)能(neng)溶解于(yu)(yu)脂肪，引(yin)發(fa)動物中樞(shu)神經(jing)疾病，致(zhi)(zhi)畸(ji)、致(zhi)(zhi)變(bian)、致(zhi)(zhi)癌甚(shen)至死亡。鎘使骨(gu)(gu)質(zhi)軟(ruan)化、骨(gu)(gu)骼(ge)變(bian)形，嚴(yan)重時形成自然骨(gu)(gu)折，以(yi)致(zhi)(zhi)死亡。鋅的(de)鹽類使蛋白質(zhi)沉淀，對皮膚黏(nian)膜(mo)有刺(ci)激作用。鉛主要是導致(zhi)(zhi)貧血(xue)(xue)、神經(jing)功(gong)能(neng)失調和腎損(sun)傷(shang)，抑制血(xue)(xue)紅蛋白的(de)合成代謝。鎳溶解于(yu)(yu)血(xue)(xue)液，會(hui)引(yin)起(qi)血(xue)(xue)管變(bian)異(yi)。錳會(hui)引(yin)起(qi)神經(jing)性功(gong)能(neng)障(zhang)礙，綜合性功(gong)能(neng)紊亂(luan)，較重者(zhe)出現精神癥狀。
