電池型號尺寸一般是多少

電(dian)(dian)池型(xing)號尺寸有很多，包括一(yi)(yi)號二號五號七號等(deng)等(deng)，其(qi)中5號電(dian)(dian)池和7號電(dian)(dian)池是生活(huo)中最(zui)常見的兩種電(dian)(dian)池。5號電(dian)(dian)池高49.0，直徑(jing)14.0，一(yi)(yi)般用(yong)于電(dian)(dian)子玩具(ju)或數碼(ma)設備。7號電(dian)(dian)池高44.0，直徑(jing)10.0，一(yi)(yi)般用(yong)戶遙控器。

常用電池的類型有哪些

1、干電池

干電(dian)池(chi)(chi)(chi)(chi)(chi)也叫錳(meng)鋅電(dian)池(chi)(chi)(chi)(chi)(chi)，所謂(wei)干電(dian)池(chi)(chi)(chi)(chi)(chi)是相(xiang)對于伏打(da)電(dian)池(chi)(chi)(chi)(chi)(chi)而言，所謂(wei)錳(meng)鋅是指其原(yuan)材料(liao)。針(zhen)對其它(ta)(ta)材料(liao)的(de)干電(dian)池(chi)(chi)(chi)(chi)(chi)如氧化(hua)銀電(dian)池(chi)(chi)(chi)(chi)(chi)，鎳鎘電(dian)池(chi)(chi)(chi)(chi)(chi)而言。錳(meng)鋅電(dian)池(chi)(chi)(chi)(chi)(chi)的(de)電(dian)壓(ya)是15V。干電(dian)池(chi)(chi)(chi)(chi)(chi)是消耗化(hua)學原(yuan)料(liao)產生電(dian)能的(de)，它(ta)(ta)的(de)電(dian)壓(ya)不(bu)高(gao)，所能產生的(de)持續電(dian)流不(bu)能超過(guo)1安培，因此它(ta)(ta)在一(yi)些小電(dian)器(qi)中使(shi)用(yong)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碼設備(bei)。

3、鋰電池

鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)是(shi)指以鋰(li)(li)為負(fu)極的電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。按所用(yong)電(dian)(dian)(dian)解(jie)(jie)質(zhi)不同(tong)分為高(gao)溫(wen)熔融鹽(yan)鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)、有機電(dian)(dian)(dian)解(jie)(jie)質(zhi)鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)、無(wu)機非水電(dian)(dian)(dian)解(jie)(jie)質(zhi)鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)、固體電(dian)(dian)(dian)解(jie)(jie)質(zhi)鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)、鋰(li)(li)水電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)這幾種(zhong)類(lei)型。鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的優點是(shi)單體電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)(dian)壓(ya)高(gao)，比能量大，儲存(cun)壽(shou)命長（可達10年），高(gao)低溫(wen)性(xing)能好，可在-40～150℃使(shi)用(yong)。缺點是(shi)價格昂貴，安全(quan)性(xing)不高(gao)。另外電(dian)(dian)(dian)壓(ya)滯后(hou)和安全(quan)問(wen)題尚待(dai)改善(shan)。

廢電池有什么危害

廢舊電(dian)池中的金屬汞能溶解(jie)于(yu)脂肪，引發動物(wu)中樞神經疾(ji)病，致(zhi)(zhi)畸、致(zhi)(zhi)變(bian)、致(zhi)(zhi)癌(ai)甚至死(si)亡(wang)。鎘使骨(gu)質(zhi)軟化、骨(gu)骼變(bian)形，嚴重時形成(cheng)自然骨(gu)折，以致(zhi)(zhi)死(si)亡(wang)。鋅的鹽(yan)類使蛋白(bai)質(zhi)沉(chen)淀，對皮(pi)膚黏膜有刺激作用。鉛主要是(shi)導致(zhi)(zhi)貧血、神經功(gong)能失調和腎(shen)損傷，抑制血紅蛋白(bai)的合(he)成(cheng)代(dai)謝。鎳溶解(jie)于(yu)血液，會(hui)引起(qi)血管變(bian)異。錳會(hui)引起(qi)神經性功(gong)能障礙，綜(zong)合(he)性功(gong)能紊亂，較重者(zhe)出現精神癥狀。
