電池型號尺寸一般是多少

電池型(xing)號(hao)尺寸有很多，包(bao)括一(yi)號(hao)二(er)號(hao)五號(hao)七號(hao)等等，其中5號(hao)電池和(he)7號(hao)電池是生活中最常見的兩種電池。5號(hao)電池高49.0，直徑(jing)14.0，一(yi)般用于電子玩(wan)具或(huo)數碼設備。7號(hao)電池高44.0，直徑(jing)10.0，一(yi)般用戶(hu)遙控器。

常用電池的類型有哪些

1、干電池

干電(dian)(dian)池(chi)也叫錳鋅(xin)電(dian)(dian)池(chi)，所(suo)(suo)謂(wei)干電(dian)(dian)池(chi)是(shi)相對于伏打電(dian)(dian)池(chi)而(er)言(yan)(yan)，所(suo)(suo)謂(wei)錳鋅(xin)是(shi)指其原材(cai)料。針對其它材(cai)料的(de)干電(dian)(dian)池(chi)如氧化銀電(dian)(dian)池(chi)，鎳鎘電(dian)(dian)池(chi)而(er)言(yan)(yan)。錳鋅(xin)電(dian)(dian)池(chi)的(de)電(dian)(dian)壓(ya)是(shi)15V。干電(dian)(dian)池(chi)是(shi)消耗化學原料產生(sheng)電(dian)(dian)能的(de)，它的(de)電(dian)(dian)壓(ya)不(bu)(bu)高(gao)，所(suo)(suo)能產生(sheng)的(de)持(chi)續電(dian)(dian)流(liu)不(bu)(bu)能超過1安培，因此它在(zai)一些(xie)小電(dian)(dian)器中使用率較高(gao)。

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(ma)設(she)備。

3、鋰電池

鋰電(dian)(dian)(dian)(dian)(dian)池是指以鋰為負極(ji)的(de)電(dian)(dian)(dian)(dian)(dian)池。按所(suo)用電(dian)(dian)(dian)(dian)(dian)解(jie)質(zhi)不(bu)同分(fen)為高(gao)溫熔融鹽鋰電(dian)(dian)(dian)(dian)(dian)池、有機電(dian)(dian)(dian)(dian)(dian)解(jie)質(zhi)鋰電(dian)(dian)(dian)(dian)(dian)池、無機非水電(dian)(dian)(dian)(dian)(dian)解(jie)質(zhi)鋰電(dian)(dian)(dian)(dian)(dian)池、固體(ti)電(dian)(dian)(dian)(dian)(dian)解(jie)質(zhi)鋰電(dian)(dian)(dian)(dian)(dian)池、鋰水電(dian)(dian)(dian)(dian)(dian)池這幾(ji)種類型。鋰電(dian)(dian)(dian)(dian)(dian)池的(de)優點是單體(ti)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓高(gao)，比(bi)能量大，儲存壽命(ming)長（可(ke)達(da)10年），高(gao)低溫性(xing)能好，可(ke)在-40～150℃使用。缺點是價格昂貴，安全性(xing)不(bu)高(gao)。另外電(dian)(dian)(dian)(dian)(dian)壓滯(zhi)后(hou)和安全問題(ti)尚(shang)待改善。

廢電池有什么危害

廢舊電(dian)池中(zhong)的金屬汞能溶解于脂肪(fang)，引發動物中(zhong)樞神(shen)(shen)經疾病(bing)，致畸(ji)、致變(bian)、致癌甚至死(si)亡(wang)。鎘使(shi)骨(gu)(gu)質軟化(hua)、骨(gu)(gu)骼(ge)變(bian)形，嚴重時形成自然(ran)骨(gu)(gu)折，以致死(si)亡(wang)。鋅的鹽類(lei)使(shi)蛋(dan)白質沉淀，對(dui)皮膚黏膜有刺激作(zuo)用。鉛(qian)主要是導致貧血、神(shen)(shen)經功能失調和腎損傷，抑制(zhi)血紅蛋(dan)白的合(he)成代謝。鎳溶解于血液，會引起血管變(bian)異。錳(meng)會引起神(shen)(shen)經性功能障礙，綜(zong)合(he)性功能紊亂，較重者出現精神(shen)(shen)癥狀。
