電池型號尺寸一般是多少

電(dian)池型號(hao)(hao)(hao)(hao)(hao)尺寸有很多，包(bao)括一號(hao)(hao)(hao)(hao)(hao)二號(hao)(hao)(hao)(hao)(hao)五號(hao)(hao)(hao)(hao)(hao)七號(hao)(hao)(hao)(hao)(hao)等等，其中5號(hao)(hao)(hao)(hao)(hao)電(dian)池和7號(hao)(hao)(hao)(hao)(hao)電(dian)池是(shi)生活中最常見的兩種電(dian)池。5號(hao)(hao)(hao)(hao)(hao)電(dian)池高49.0，直(zhi)徑14.0，一般(ban)用于電(dian)子玩具或數碼設備。7號(hao)(hao)(hao)(hao)(hao)電(dian)池高44.0，直(zhi)徑10.0，一般(ban)用戶遙控器。

常用電池的類型有哪些

1、干電池

干(gan)電(dian)(dian)池(chi)(chi)(chi)也叫(jiao)錳(meng)鋅(xin)電(dian)(dian)池(chi)(chi)(chi)，所謂干(gan)電(dian)(dian)池(chi)(chi)(chi)是(shi)相對于伏打電(dian)(dian)池(chi)(chi)(chi)而言，所謂錳(meng)鋅(xin)是(shi)指其原材(cai)料。針對其它材(cai)料的(de)干(gan)電(dian)(dian)池(chi)(chi)(chi)如氧化(hua)銀電(dian)(dian)池(chi)(chi)(chi)，鎳鎘(ge)電(dian)(dian)池(chi)(chi)(chi)而言。錳(meng)鋅(xin)電(dian)(dian)池(chi)(chi)(chi)的(de)電(dian)(dian)壓是(shi)15V。干(gan)電(dian)(dian)池(chi)(chi)(chi)是(shi)消耗化(hua)學(xue)原料產生電(dian)(dian)能的(de)，它的(de)電(dian)(dian)壓不高，所能產生的(de)持續電(dian)(dian)流不能超過(guo)1安(an)培，因此它在一(yi)些小電(dian)(dian)器中(zhong)使(shi)用率較(jiao)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用(yong)于(yu)數碼設備。

3、鋰電池

鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)是(shi)指以鋰(li)(li)為負極的電(dian)(dian)(dian)池(chi)(chi)。按所用電(dian)(dian)(dian)解(jie)質(zhi)(zhi)不同分為高溫熔融鹽鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)、有機電(dian)(dian)(dian)解(jie)質(zhi)(zhi)鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)、無機非水電(dian)(dian)(dian)解(jie)質(zhi)(zhi)鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)、固體(ti)電(dian)(dian)(dian)解(jie)質(zhi)(zhi)鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)、鋰(li)(li)水電(dian)(dian)(dian)池(chi)(chi)這幾(ji)種類型。鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)的優點是(shi)單體(ti)電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)壓(ya)高，比能(neng)量大，儲存壽命(ming)長（可達10年），高低溫性(xing)能(neng)好，可在-40～150℃使用。缺點是(shi)價格昂貴，安(an)全(quan)(quan)性(xing)不高。另外電(dian)(dian)(dian)壓(ya)滯后和安(an)全(quan)(quan)問題尚待改善。

廢電池有什么危害

廢(fei)舊電池中的金屬汞能溶解(jie)于(yu)脂肪，引發(fa)動物中樞神經(jing)(jing)疾(ji)病，致(zhi)(zhi)畸、致(zhi)(zhi)變、致(zhi)(zhi)癌甚至(zhi)死亡(wang)。鎘使骨質(zhi)軟化(hua)、骨骼變形(xing)，嚴重(zhong)時形(xing)成自然骨折(zhe)，以致(zhi)(zhi)死亡(wang)。鋅(xin)的鹽類使蛋白質(zhi)沉淀，對皮膚黏膜有刺激作用。鉛主(zhu)要是導致(zhi)(zhi)貧血、神經(jing)(jing)功(gong)能失調和腎損傷，抑制血紅(hong)蛋白的合成代(dai)謝(xie)。鎳溶解(jie)于(yu)血液，會(hui)引起(qi)血管(guan)變異。錳會(hui)引起(qi)神經(jing)(jing)性功(gong)能障礙，綜合性功(gong)能紊亂，較重(zhong)者(zhe)出現精(jing)神癥狀。
