電池行業簡介

電池型號尺寸一般是多少

電(dian)池型號(hao)(hao)尺(chi)寸(cun)有很(hen)多(duo)，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)池和7號(hao)(hao)電(dian)池是生活中最(zui)常(chang)見的兩種(zhong)電(dian)池。5號(hao)(hao)電(dian)池高(gao)49.0，直徑(jing)14.0，一般用于電(dian)子玩(wan)具或(huo)數碼設備。7號(hao)(hao)電(dian)池高(gao)44.0，直徑(jing)10.0，一般用戶遙控器。

常用電池的類型有哪些

1、干電池

干電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)也叫錳(meng)(meng)鋅電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，所謂(wei)干電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是(shi)(shi)相對于伏打電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)而言，所謂(wei)錳(meng)(meng)鋅是(shi)(shi)指其(qi)(qi)原(yuan)(yuan)材(cai)料(liao)。針對其(qi)(qi)它材(cai)料(liao)的干電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)如氧化銀電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，鎳鎘電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)而言。錳(meng)(meng)鋅電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的電(dian)(dian)(dian)(dian)壓(ya)是(shi)(shi)15V。干電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是(shi)(shi)消耗化學原(yuan)(yuan)料(liao)產生電(dian)(dian)(dian)(dian)能(neng)的，它的電(dian)(dian)(dian)(dian)壓(ya)不(bu)高，所能(neng)產生的持續電(dian)(dian)(dian)(dian)流不(bu)能(neng)超過1安培，因此它在一些小電(dian)(dian)(dian)(dian)器中使用(yong)率(lv)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用于(yu)數碼設備。

3、鋰電池

鋰(li)(li)電(dian)池(chi)(chi)(chi)是(shi)指以(yi)鋰(li)(li)為負極的(de)電(dian)池(chi)(chi)(chi)。按所用電(dian)解(jie)(jie)質不同分為高(gao)溫熔融鹽(yan)鋰(li)(li)電(dian)池(chi)(chi)(chi)、有機(ji)電(dian)解(jie)(jie)質鋰(li)(li)電(dian)池(chi)(chi)(chi)、無機(ji)非水電(dian)解(jie)(jie)質鋰(li)(li)電(dian)池(chi)(chi)(chi)、固(gu)體電(dian)解(jie)(jie)質鋰(li)(li)電(dian)池(chi)(chi)(chi)、鋰(li)(li)水電(dian)池(chi)(chi)(chi)這幾(ji)種類型。鋰(li)(li)電(dian)池(chi)(chi)(chi)的(de)優點是(shi)單體電(dian)池(chi)(chi)(chi)電(dian)壓高(gao)，比能量(liang)大，儲(chu)存壽(shou)命(ming)長（可(ke)達10年），高(gao)低溫性能好，可(ke)在-40～150℃使(shi)用。缺點是(shi)價格(ge)昂貴，安全性不高(gao)。另外電(dian)壓滯后和安全問題尚待(dai)改善。

廢電池有什么危害

廢(fei)舊電池中的金屬(shu)汞(gong)能溶(rong)(rong)解(jie)于脂肪，引發動物中樞神(shen)經疾病(bing)，致畸、致變、致癌甚至死(si)亡。鎘使(shi)骨(gu)質軟化、骨(gu)骼變形，嚴重時形成(cheng)自(zi)然(ran)骨(gu)折，以(yi)致死(si)亡。鋅的鹽類使(shi)蛋(dan)白質沉(chen)淀，對皮膚黏膜有刺激作(zuo)用(yong)。鉛主要(yao)是導致貧血、神(shen)經功能失調和腎(shen)損(sun)傷，抑制血紅蛋(dan)白的合成(cheng)代謝。鎳溶(rong)(rong)解(jie)于血液，會引起血管變異。錳會引起神(shen)經性(xing)功能障(zhang)礙，綜合性(xing)功能紊亂(luan)，較重者出現精神(shen)癥狀。
