電池型號尺寸一般是多少

電(dian)(dian)池(chi)型號(hao)(hao)(hao)尺寸(cun)有(you)很多，包括(kuo)一(yi)(yi)號(hao)(hao)(hao)二號(hao)(hao)(hao)五號(hao)(hao)(hao)七號(hao)(hao)(hao)等(deng)等(deng)，其中5號(hao)(hao)(hao)電(dian)(dian)池(chi)和7號(hao)(hao)(hao)電(dian)(dian)池(chi)是生活(huo)中最常見(jian)的兩種電(dian)(dian)池(chi)。5號(hao)(hao)(hao)電(dian)(dian)池(chi)高49.0，直徑(jing)14.0，一(yi)(yi)般用于電(dian)(dian)子玩具或數碼設備。7號(hao)(hao)(hao)電(dian)(dian)池(chi)高44.0，直徑(jing)10.0，一(yi)(yi)般用戶遙控器。

常用電池的類型有哪些

1、干電池

干(gan)電(dian)池(chi)(chi)也叫錳鋅(xin)電(dian)池(chi)(chi)，所(suo)謂干(gan)電(dian)池(chi)(chi)是(shi)(shi)相對于伏打電(dian)池(chi)(chi)而言，所(suo)謂錳鋅(xin)是(shi)(shi)指(zhi)其(qi)原材(cai)料(liao)。針對其(qi)它(ta)材(cai)料(liao)的(de)(de)干(gan)電(dian)池(chi)(chi)如氧化銀電(dian)池(chi)(chi)，鎳鎘電(dian)池(chi)(chi)而言。錳鋅(xin)電(dian)池(chi)(chi)的(de)(de)電(dian)壓是(shi)(shi)15V。干(gan)電(dian)池(chi)(chi)是(shi)(shi)消(xiao)耗化學原料(liao)產生電(dian)能(neng)(neng)(neng)的(de)(de)，它(ta)的(de)(de)電(dian)壓不高，所(suo)能(neng)(neng)(neng)產生的(de)(de)持續電(dian)流不能(neng)(neng)(neng)超過1安培(pei)，因(yin)此它(ta)在一些小電(dian)器中使(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于數碼設備。

3、鋰電池

鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)是(shi)指以鋰(li)(li)為(wei)負極的(de)(de)電(dian)(dian)(dian)(dian)池(chi)。按所(suo)用(yong)電(dian)(dian)(dian)(dian)解(jie)(jie)質(zhi)不(bu)同分為(wei)高(gao)溫熔(rong)融鹽鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)、有機(ji)電(dian)(dian)(dian)(dian)解(jie)(jie)質(zhi)鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)、無(wu)機(ji)非水(shui)電(dian)(dian)(dian)(dian)解(jie)(jie)質(zhi)鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)、固體電(dian)(dian)(dian)(dian)解(jie)(jie)質(zhi)鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)、鋰(li)(li)水(shui)電(dian)(dian)(dian)(dian)池(chi)這幾種類型。鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)的(de)(de)優點是(shi)單體電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓(ya)高(gao)，比能量(liang)大(da)，儲存(cun)壽(shou)命(ming)長（可達10年），高(gao)低溫性(xing)能好，可在-40～150℃使用(yong)。缺點是(shi)價格昂貴，安(an)全性(xing)不(bu)高(gao)。另(ling)外電(dian)(dian)(dian)(dian)壓(ya)滯(zhi)后和安(an)全問題(ti)尚待改善。

廢電池有什么危害

廢(fei)舊(jiu)電池中(zhong)的金屬汞能(neng)溶(rong)解(jie)于脂肪(fang)，引(yin)發動物中(zhong)樞神(shen)經(jing)疾病(bing)，致畸、致變、致癌甚至死(si)亡。鎘使骨(gu)質軟化、骨(gu)骼(ge)變形(xing)，嚴(yan)重(zhong)(zhong)時形(xing)成自然(ran)骨(gu)折，以致死(si)亡。鋅(xin)的鹽類使蛋(dan)白質沉(chen)淀，對皮膚黏膜有刺激作用(yong)。鉛(qian)主(zhu)要是(shi)導(dao)致貧(pin)血(xue)、神(shen)經(jing)功能(neng)失調和腎損傷，抑制血(xue)紅蛋(dan)白的合(he)(he)成代謝。鎳溶(rong)解(jie)于血(xue)液，會(hui)引(yin)起血(xue)管(guan)變異。錳會(hui)引(yin)起神(shen)經(jing)性功能(neng)障礙，綜(zong)合(he)(he)性功能(neng)紊亂(luan)，較重(zhong)(zhong)者出現精神(shen)癥(zheng)狀。
