電池行業簡介

電池型號尺寸一般是多少

電(dian)池(chi)(chi)型號尺寸有很(hen)多，包括一號二號五號七號等等，其中5號電(dian)池(chi)(chi)和7號電(dian)池(chi)(chi)是生(sheng)活中最(zui)常(chang)見的兩種電(dian)池(chi)(chi)。5號電(dian)池(chi)(chi)高(gao)(gao)49.0，直徑(jing)14.0，一般用(yong)于電(dian)子玩具(ju)或數碼設備。7號電(dian)池(chi)(chi)高(gao)(gao)44.0，直徑(jing)10.0，一般用(yong)戶遙控器。

常用電池的類型有哪些

1、干電池

干(gan)電(dian)(dian)池也(ye)叫錳鋅(xin)(xin)電(dian)(dian)池，所謂干(gan)電(dian)(dian)池是(shi)相對于伏打電(dian)(dian)池而(er)言，所謂錳鋅(xin)(xin)是(shi)指(zhi)其原材料。針對其它(ta)材料的干(gan)電(dian)(dian)池如氧化銀電(dian)(dian)池，鎳鎘(ge)電(dian)(dian)池而(er)言。錳鋅(xin)(xin)電(dian)(dian)池的電(dian)(dian)壓(ya)是(shi)15V。干(gan)電(dian)(dian)池是(shi)消(xiao)耗化學原料產生(sheng)電(dian)(dian)能的，它(ta)的電(dian)(dian)壓(ya)不高，所能產生(sheng)的持續電(dian)(dian)流(liu)不能超過1安培(pei)，因此它(ta)在(zai)一些(xie)小電(dian)(dian)器中使(shi)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于數碼設備。

3、鋰電池

鋰電(dian)(dian)(dian)(dian)池(chi)(chi)是指以鋰為(wei)負極的電(dian)(dian)(dian)(dian)池(chi)(chi)。按(an)所用電(dian)(dian)(dian)(dian)解(jie)質不(bu)同分為(wei)高(gao)溫熔(rong)融(rong)鹽鋰電(dian)(dian)(dian)(dian)池(chi)(chi)、有(you)機(ji)電(dian)(dian)(dian)(dian)解(jie)質鋰電(dian)(dian)(dian)(dian)池(chi)(chi)、無(wu)機(ji)非水電(dian)(dian)(dian)(dian)解(jie)質鋰電(dian)(dian)(dian)(dian)池(chi)(chi)、固體電(dian)(dian)(dian)(dian)解(jie)質鋰電(dian)(dian)(dian)(dian)池(chi)(chi)、鋰水電(dian)(dian)(dian)(dian)池(chi)(chi)這幾種類型。鋰電(dian)(dian)(dian)(dian)池(chi)(chi)的優點是單體電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)壓(ya)高(gao)，比能量大，儲存壽命長(chang)（可達10年(nian)），高(gao)低溫性能好，可在-40～150℃使用。缺點是價(jia)格昂貴，安(an)全性不(bu)高(gao)。另外電(dian)(dian)(dian)(dian)壓(ya)滯后和安(an)全問題尚待(dai)改(gai)善。

廢電池有什么危害

廢(fei)舊(jiu)電池(chi)中的(de)(de)(de)金屬汞能(neng)溶解(jie)于脂肪，引發動物中樞(shu)神經疾病，致(zhi)(zhi)畸、致(zhi)(zhi)變、致(zhi)(zhi)癌甚至死(si)亡。鎘(ge)使(shi)骨(gu)質(zhi)軟化、骨(gu)骼變形，嚴重時形成自然骨(gu)折，以致(zhi)(zhi)死(si)亡。鋅的(de)(de)(de)鹽類使(shi)蛋白質(zhi)沉淀，對皮膚黏膜有刺激作用。鉛主(zhu)要(yao)是導致(zhi)(zhi)貧血(xue)、神經功能(neng)失調和腎損(sun)傷，抑(yi)制血(xue)紅蛋白的(de)(de)(de)合成代(dai)謝(xie)。鎳溶解(jie)于血(xue)液，會(hui)引起血(xue)管變異(yi)。錳會(hui)引起神經性功能(neng)障礙，綜(zong)合性功能(neng)紊(wen)亂，較重者出現精神癥狀。
