電池型號尺寸一般是多少

電(dian)池(chi)型號(hao)(hao)尺寸有很多，包括一號(hao)(hao)二號(hao)(hao)五號(hao)(hao)七號(hao)(hao)等等，其中5號(hao)(hao)電(dian)池(chi)和7號(hao)(hao)電(dian)池(chi)是(shi)生活中最(zui)常見的兩種電(dian)池(chi)。5號(hao)(hao)電(dian)池(chi)高(gao)49.0，直徑14.0，一般用(yong)于電(dian)子玩具或(huo)數(shu)碼設備(bei)。7號(hao)(hao)電(dian)池(chi)高(gao)44.0，直徑10.0，一般用(yong)戶遙(yao)控器(qi)。

常用電池的類型有哪些

1、干電池

干(gan)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)也叫錳(meng)鋅(xin)(xin)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，所(suo)謂(wei)干(gan)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)相對于伏打(da)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)而(er)言(yan)，所(suo)謂(wei)錳(meng)鋅(xin)(xin)是(shi)指其原(yuan)材料。針對其它(ta)材料的干(gan)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)如氧化銀電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，鎳鎘電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)而(er)言(yan)。錳(meng)鋅(xin)(xin)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的電(dian)(dian)(dian)(dian)(dian)壓(ya)是(shi)15V。干(gan)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)消耗化學原(yuan)料產(chan)生電(dian)(dian)(dian)(dian)(dian)能(neng)的，它(ta)的電(dian)(dian)(dian)(dian)(dian)壓(ya)不高(gao)，所(suo)能(neng)產(chan)生的持續電(dian)(dian)(dian)(dian)(dian)流不能(neng)超過1安培，因此它(ta)在(zai)一些小(xiao)電(dian)(dian)(dian)(dian)(dian)器(qi)中使(shi)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用于數(shu)碼設備。

3、鋰電池

鋰(li)(li)(li)電(dian)(dian)(dian)(dian)(dian)池是指(zhi)以鋰(li)(li)(li)為負(fu)極的電(dian)(dian)(dian)(dian)(dian)池。按(an)所用電(dian)(dian)(dian)(dian)(dian)解(jie)質(zhi)(zhi)不(bu)同分為高溫熔融鹽(yan)鋰(li)(li)(li)電(dian)(dian)(dian)(dian)(dian)池、有機電(dian)(dian)(dian)(dian)(dian)解(jie)質(zhi)(zhi)鋰(li)(li)(li)電(dian)(dian)(dian)(dian)(dian)池、無機非水(shui)電(dian)(dian)(dian)(dian)(dian)解(jie)質(zhi)(zhi)鋰(li)(li)(li)電(dian)(dian)(dian)(dian)(dian)池、固(gu)體電(dian)(dian)(dian)(dian)(dian)解(jie)質(zhi)(zhi)鋰(li)(li)(li)電(dian)(dian)(dian)(dian)(dian)池、鋰(li)(li)(li)水(shui)電(dian)(dian)(dian)(dian)(dian)池這幾種(zhong)類型(xing)。鋰(li)(li)(li)電(dian)(dian)(dian)(dian)(dian)池的優點是單體電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓(ya)高，比能(neng)量大(da)，儲(chu)存壽命長（可(ke)達(da)10年），高低溫性能(neng)好(hao)，可(ke)在-40～150℃使用。缺點是價格昂(ang)貴，安(an)全性不(bu)高。另外電(dian)(dian)(dian)(dian)(dian)壓(ya)滯(zhi)后和安(an)全問題尚待改善。

廢電池有什么危害

廢舊(jiu)電池中(zhong)的金屬汞(gong)能溶解(jie)于脂肪(fang)，引(yin)(yin)發動物(wu)中(zhong)樞神經疾病，致畸、致變、致癌甚至死(si)亡。鎘使(shi)骨(gu)質(zhi)軟化、骨(gu)骼變形(xing)，嚴重(zhong)時形(xing)成(cheng)自然骨(gu)折(zhe)，以致死(si)亡。鋅(xin)的鹽類使(shi)蛋(dan)白(bai)質(zhi)沉淀，對皮膚黏膜有刺激作用。鉛主(zhu)要是(shi)導致貧(pin)血、神經功(gong)(gong)能失調和(he)腎(shen)損傷，抑(yi)制血紅蛋(dan)白(bai)的合(he)成(cheng)代(dai)謝。鎳溶解(jie)于血液，會引(yin)(yin)起(qi)血管變異。錳會引(yin)(yin)起(qi)神經性功(gong)(gong)能障礙，綜合(he)性功(gong)(gong)能紊亂，較重(zhong)者出現(xian)精(jing)神癥狀。
