電池行業簡介

電池型號尺寸一般是多少

電(dian)(dian)池型號(hao)尺寸有很多，包括一號(hao)二號(hao)五號(hao)七號(hao)等等，其(qi)中5號(hao)電(dian)(dian)池和7號(hao)電(dian)(dian)池是生活中最(zui)常見的(de)兩種電(dian)(dian)池。5號(hao)電(dian)(dian)池高49.0，直徑14.0，一般用于電(dian)(dian)子玩具或數碼設備。7號(hao)電(dian)(dian)池高44.0，直徑10.0，一般用戶遙控器(qi)。

常用電池的類型有哪些

1、干電池

干(gan)(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)也叫錳(meng)(meng)鋅(xin)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，所謂(wei)干(gan)(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)是相對(dui)于伏打電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)而言(yan)，所謂(wei)錳(meng)(meng)鋅(xin)是指(zhi)其原(yuan)材(cai)料(liao)。針對(dui)其它(ta)材(cai)料(liao)的(de)干(gan)(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)如氧化銀電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，鎳鎘(ge)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)而言(yan)。錳(meng)(meng)鋅(xin)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)是15V。干(gan)(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)是消耗化學原(yuan)料(liao)產(chan)(chan)生(sheng)電(dian)(dian)(dian)(dian)能(neng)的(de)，它(ta)的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)不(bu)高，所能(neng)產(chan)(chan)生(sheng)的(de)持續電(dian)(dian)(dian)(dian)流(liu)不(bu)能(neng)超過1安培，因此它(ta)在一些小(xiao)電(dian)(dian)(dian)(dian)器中使用(yong)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備。

3、鋰電池

鋰(li)電(dian)池(chi)(chi)是指以鋰(li)為(wei)負極的電(dian)池(chi)(chi)。按所用(yong)電(dian)解(jie)質不(bu)同分為(wei)高(gao)(gao)溫熔融鹽鋰(li)電(dian)池(chi)(chi)、有機電(dian)解(jie)質鋰(li)電(dian)池(chi)(chi)、無機非水電(dian)解(jie)質鋰(li)電(dian)池(chi)(chi)、固體(ti)電(dian)解(jie)質鋰(li)電(dian)池(chi)(chi)、鋰(li)水電(dian)池(chi)(chi)這幾(ji)種類型。鋰(li)電(dian)池(chi)(chi)的優點是單體(ti)電(dian)池(chi)(chi)電(dian)壓高(gao)(gao)，比(bi)能(neng)量(liang)大，儲(chu)存壽命長（可(ke)達10年(nian)），高(gao)(gao)低溫性能(neng)好，可(ke)在-40～150℃使用(yong)。缺點是價格(ge)昂貴，安全性不(bu)高(gao)(gao)。另外電(dian)壓滯后和安全問題尚待(dai)改(gai)善。

廢電池有什么危害

廢舊電池中(zhong)(zhong)的金(jin)屬汞能溶(rong)(rong)解于(yu)脂肪，引發動物中(zhong)(zhong)樞(shu)神經疾(ji)病，致(zhi)畸、致(zhi)變、致(zhi)癌甚至死(si)亡(wang)。鎘使骨(gu)(gu)質軟(ruan)化、骨(gu)(gu)骼變形(xing)，嚴重時形(xing)成自(zi)然(ran)骨(gu)(gu)折，以致(zhi)死(si)亡(wang)。鋅的鹽類使蛋白(bai)質沉淀，對皮膚(fu)黏(nian)膜有刺激(ji)作用。鉛(qian)主要是(shi)導(dao)致(zhi)貧(pin)血(xue)、神經功(gong)能失調和腎損(sun)傷，抑制血(xue)紅蛋白(bai)的合(he)成代謝。鎳溶(rong)(rong)解于(yu)血(xue)液，會(hui)引起血(xue)管變異。錳會(hui)引起神經性功(gong)能障礙，綜(zong)合(he)性功(gong)能紊亂，較重者出現精神癥(zheng)狀(zhuang)。
