電池行業簡介

電池型號尺寸一般是多少

電(dian)池(chi)(chi)(chi)型號尺寸有很多，包(bao)括一(yi)號二(er)號五號七號等(deng)等(deng)，其(qi)中5號電(dian)池(chi)(chi)(chi)和(he)7號電(dian)池(chi)(chi)(chi)是生活中最常見的兩種電(dian)池(chi)(chi)(chi)。5號電(dian)池(chi)(chi)(chi)高49.0，直徑(jing)14.0，一(yi)般用于電(dian)子玩具或數(shu)碼設備(bei)。7號電(dian)池(chi)(chi)(chi)高44.0，直徑(jing)10.0，一(yi)般用戶遙控器。

常用電池的類型有哪些

1、干電池

干電(dian)(dian)(dian)池(chi)也(ye)叫錳鋅(xin)電(dian)(dian)(dian)池(chi)，所(suo)謂干電(dian)(dian)(dian)池(chi)是(shi)相對于伏打電(dian)(dian)(dian)池(chi)而(er)言，所(suo)謂錳鋅(xin)是(shi)指其(qi)原材料。針對其(qi)它(ta)(ta)材料的干電(dian)(dian)(dian)池(chi)如(ru)氧化銀(yin)電(dian)(dian)(dian)池(chi)，鎳鎘電(dian)(dian)(dian)池(chi)而(er)言。錳鋅(xin)電(dian)(dian)(dian)池(chi)的電(dian)(dian)(dian)壓(ya)是(shi)15V。干電(dian)(dian)(dian)池(chi)是(shi)消(xiao)耗化學原料產(chan)生電(dian)(dian)(dian)能(neng)的，它(ta)(ta)的電(dian)(dian)(dian)壓(ya)不(bu)高，所(suo)能(neng)產(chan)生的持續電(dian)(dian)(dian)流不(bu)能(neng)超(chao)過1安培，因此它(ta)(ta)在一些小電(dian)(dian)(dian)器中使用率較高。

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(neng)用于數碼設(she)備。

3、鋰電池

鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)是(shi)指以鋰為(wei)負(fu)極的電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。按所用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)解(jie)質不(bu)同分(fen)為(wei)高溫熔融(rong)鹽鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)、有(you)機(ji)電(dian)(dian)(dian)(dian)(dian)(dian)解(jie)質鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)、無機(ji)非水電(dian)(dian)(dian)(dian)(dian)(dian)解(jie)質鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)、固體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)解(jie)質鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)、鋰水電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)這幾種類型。鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的優點是(shi)單體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)高，比能(neng)量大，儲存壽(shou)命長（可(ke)達(da)10年(nian)），高低(di)溫性(xing)能(neng)好，可(ke)在(zai)-40～150℃使用(yong)。缺點是(shi)價格昂貴，安(an)全性(xing)不(bu)高。另外電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)滯后和安(an)全問(wen)題尚待改善。

廢電池有什么危害

廢舊電池中的(de)(de)金屬汞能(neng)溶(rong)解(jie)于脂肪，引發動物中樞神(shen)經疾病，致畸、致變(bian)、致癌甚至死亡(wang)。鎘使(shi)骨(gu)質軟化、骨(gu)骼變(bian)形(xing)(xing)，嚴(yan)重時形(xing)(xing)成(cheng)自然骨(gu)折(zhe)，以致死亡(wang)。鋅的(de)(de)鹽類(lei)使(shi)蛋(dan)白質沉淀，對皮膚黏膜有刺激作用(yong)。鉛主要是導致貧血、神(shen)經功能(neng)失調和腎損傷，抑(yi)制血紅蛋(dan)白的(de)(de)合成(cheng)代謝。鎳溶(rong)解(jie)于血液，會引起(qi)血管變(bian)異。錳會引起(qi)神(shen)經性功能(neng)障礙(ai)，綜(zong)合性功能(neng)紊亂(luan)，較重者出(chu)現精神(shen)癥狀(zhuang)。
