電池行業簡介

電池型號尺寸一般是多少

電池(chi)(chi)型號尺寸有很多，包(bao)括一(yi)號二號五號七號等等，其中(zhong)5號電池(chi)(chi)和(he)7號電池(chi)(chi)是生活中(zhong)最(zui)常見的兩種(zhong)電池(chi)(chi)。5號電池(chi)(chi)高49.0，直徑14.0，一(yi)般用(yong)(yong)于電子玩具(ju)或數碼設備。7號電池(chi)(chi)高44.0，直徑10.0，一(yi)般用(yong)(yong)戶遙控器。

常用電池的類型有哪些

1、干電池

干電(dian)(dian)池(chi)(chi)(chi)也(ye)叫錳(meng)(meng)(meng)鋅(xin)電(dian)(dian)池(chi)(chi)(chi)，所(suo)(suo)謂干電(dian)(dian)池(chi)(chi)(chi)是(shi)相(xiang)對(dui)于伏打電(dian)(dian)池(chi)(chi)(chi)而言，所(suo)(suo)謂錳(meng)(meng)(meng)鋅(xin)是(shi)指(zhi)其原材料。針對(dui)其它材料的(de)干電(dian)(dian)池(chi)(chi)(chi)如(ru)氧化銀電(dian)(dian)池(chi)(chi)(chi)，鎳鎘電(dian)(dian)池(chi)(chi)(chi)而言。錳(meng)(meng)(meng)鋅(xin)電(dian)(dian)池(chi)(chi)(chi)的(de)電(dian)(dian)壓是(shi)15V。干電(dian)(dian)池(chi)(chi)(chi)是(shi)消耗化學原料產生電(dian)(dian)能的(de)，它的(de)電(dian)(dian)壓不(bu)(bu)高，所(suo)(suo)能產生的(de)持(chi)續電(dian)(dian)流不(bu)(bu)能超過1安培，因此(ci)它在一些小電(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(bu)能用(yong)于數碼設備。

3、鋰電池

鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)指以鋰(li)為負極的電(dian)(dian)(dian)(dian)池(chi)(chi)。按所用電(dian)(dian)(dian)(dian)解質不同分為高溫熔融鹽鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)、有機電(dian)(dian)(dian)(dian)解質鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)、無機非水(shui)(shui)電(dian)(dian)(dian)(dian)解質鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)、固體電(dian)(dian)(dian)(dian)解質鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)、鋰(li)水(shui)(shui)電(dian)(dian)(dian)(dian)池(chi)(chi)這(zhe)幾種類(lei)型。鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)的優點是(shi)單體電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)壓(ya)高，比(bi)能(neng)量大(da)，儲(chu)存壽命長（可達(da)10年），高低(di)溫性(xing)能(neng)好(hao)，可在-40～150℃使用。缺點是(shi)價格昂貴，安(an)全性(xing)不高。另外電(dian)(dian)(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

廢舊(jiu)電池中(zhong)的(de)金屬汞能(neng)(neng)溶(rong)解于脂肪，引(yin)發(fa)動物中(zhong)樞神經疾病(bing)，致(zhi)畸、致(zhi)變(bian)(bian)、致(zhi)癌(ai)甚至死亡。鎘使骨質軟化、骨骼變(bian)(bian)形，嚴重時形成自然骨折，以致(zhi)死亡。鋅的(de)鹽類使蛋白(bai)質沉淀(dian)，對(dui)皮膚黏膜有(you)刺(ci)激作(zuo)用。鉛主要是導致(zhi)貧血(xue)、神經功能(neng)(neng)失調和(he)腎損傷，抑(yi)制血(xue)紅蛋白(bai)的(de)合成代謝(xie)。鎳溶(rong)解于血(xue)液，會(hui)引(yin)起血(xue)管(guan)變(bian)(bian)異。錳(meng)會(hui)引(yin)起神經性功能(neng)(neng)障礙，綜合性功能(neng)(neng)紊亂，較重者出現精(jing)神癥狀(zhuang)。
