電池型號尺寸一般是多少

電(dian)(dian)池型號(hao)(hao)(hao)(hao)尺(chi)寸有很多，包括一(yi)(yi)(yi)號(hao)(hao)(hao)(hao)二號(hao)(hao)(hao)(hao)五號(hao)(hao)(hao)(hao)七號(hao)(hao)(hao)(hao)等等，其(qi)中(zhong)5號(hao)(hao)(hao)(hao)電(dian)(dian)池和7號(hao)(hao)(hao)(hao)電(dian)(dian)池是生活中(zhong)最常見的兩種(zhong)電(dian)(dian)池。5號(hao)(hao)(hao)(hao)電(dian)(dian)池高(gao)(gao)49.0，直徑14.0，一(yi)(yi)(yi)般(ban)用于電(dian)(dian)子玩(wan)具或(huo)數碼設備。7號(hao)(hao)(hao)(hao)電(dian)(dian)池高(gao)(gao)44.0，直徑10.0，一(yi)(yi)(yi)般(ban)用戶遙(yao)控器。

常用電池的類型有哪些

1、干電池

干電(dian)(dian)池(chi)(chi)(chi)也叫錳鋅電(dian)(dian)池(chi)(chi)(chi)，所(suo)謂(wei)干電(dian)(dian)池(chi)(chi)(chi)是(shi)相對(dui)于伏打電(dian)(dian)池(chi)(chi)(chi)而言，所(suo)謂(wei)錳鋅是(shi)指其原材料。針對(dui)其它材料的(de)(de)干電(dian)(dian)池(chi)(chi)(chi)如氧化銀(yin)電(dian)(dian)池(chi)(chi)(chi)，鎳鎘電(dian)(dian)池(chi)(chi)(chi)而言。錳鋅電(dian)(dian)池(chi)(chi)(chi)的(de)(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)(de)，它的(de)(de)電(dian)(dian)壓不高，所(suo)能產生的(de)(de)持續(xu)電(dian)(dian)流不能超過1安培，因此(ci)它在一些小電(dian)(dian)器(qi)中(zhong)使用(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(neng)用(yong)于數(shu)碼設(she)備。

3、鋰電池

鋰(li)(li)(li)電(dian)(dian)池(chi)(chi)(chi)是(shi)指以(yi)鋰(li)(li)(li)為負(fu)極的電(dian)(dian)池(chi)(chi)(chi)。按所用(yong)電(dian)(dian)解(jie)質(zhi)不同分為高溫熔融(rong)鹽鋰(li)(li)(li)電(dian)(dian)池(chi)(chi)(chi)、有機電(dian)(dian)解(jie)質(zhi)鋰(li)(li)(li)電(dian)(dian)池(chi)(chi)(chi)、無機非水電(dian)(dian)解(jie)質(zhi)鋰(li)(li)(li)電(dian)(dian)池(chi)(chi)(chi)、固體電(dian)(dian)解(jie)質(zhi)鋰(li)(li)(li)電(dian)(dian)池(chi)(chi)(chi)、鋰(li)(li)(li)水電(dian)(dian)池(chi)(chi)(chi)這幾(ji)種類(lei)型。鋰(li)(li)(li)電(dian)(dian)池(chi)(chi)(chi)的優點是(shi)單(dan)體電(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)壓高，比能量大，儲存壽命長（可(ke)達10年），高低溫性(xing)(xing)能好，可(ke)在-40～150℃使用(yong)。缺點是(shi)價格昂貴，安全性(xing)(xing)不高。另外電(dian)(dian)壓滯(zhi)后和安全問題尚(shang)待改善。

廢電池有什么危害

廢舊(jiu)電池中的金屬汞能溶(rong)解于脂肪(fang)，引(yin)發動物(wu)中樞神經(jing)疾病，致畸、致變、致癌甚至死亡。鎘使骨(gu)(gu)(gu)質(zhi)軟化、骨(gu)(gu)(gu)骼變形(xing)，嚴(yan)重時形(xing)成(cheng)(cheng)自(zi)然骨(gu)(gu)(gu)折，以致死亡。鋅的鹽類使蛋白質(zhi)沉淀，對皮膚黏膜有(you)刺(ci)激作用。鉛主(zhu)要是(shi)導致貧血、神經(jing)功能失調(diao)和腎損傷，抑制(zhi)血紅蛋白的合(he)(he)成(cheng)(cheng)代謝(xie)。鎳(nie)溶(rong)解于血液，會引(yin)起血管變異。錳會引(yin)起神經(jing)性(xing)功能障礙，綜合(he)(he)性(xing)功能紊亂，較重者出現精神癥狀。
