電池型號尺寸一般是多少
電(dian)池型號(hao)(hao)尺寸有(you)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)池和7號(hao)(hao)電(dian)池是(shi)生活中最常(chang)見的兩種電(dian)池。5號(hao)(hao)電(dian)池高49.0,直徑14.0,一般用于電(dian)子(zi)玩(wan)具或數碼(ma)設備。7號(hao)(hao)電(dian)池高44.0,直徑10.0,一般用戶遙(yao)控器。
常用電池的類型有哪些
1、干電池
干(gan)(gan)電(dian)池(chi)(chi)(chi)也叫(jiao)錳(meng)鋅(xin)電(dian)池(chi)(chi)(chi),所謂(wei)干(gan)(gan)電(dian)池(chi)(chi)(chi)是相對于伏打(da)電(dian)池(chi)(chi)(chi)而言,所謂(wei)錳(meng)鋅(xin)是指其(qi)原材(cai)(cai)料。針(zhen)對其(qi)它材(cai)(cai)料的干(gan)(gan)電(dian)池(chi)(chi)(chi)如氧化(hua)銀電(dian)池(chi)(chi)(chi),鎳鎘電(dian)池(chi)(chi)(chi)而言。錳(meng)鋅(xin)電(dian)池(chi)(chi)(chi)的電(dian)壓是15V。干(gan)(gan)電(dian)池(chi)(chi)(chi)是消耗化(hua)學原料產生電(dian)能的,它的電(dian)壓不高,所能產生的持續電(dian)流(liu)不能超過1安培(pei),因此它在一些小(xiao)電(dian)器中使用(yong)率較高。
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(yong)于數(shu)碼設(she)備。
3、鋰電池
鋰(li)(li)電(dian)(dian)(dian)(dian)池是(shi)指(zhi)以鋰(li)(li)為(wei)負極的(de)電(dian)(dian)(dian)(dian)池。按所(suo)用電(dian)(dian)(dian)(dian)解質(zhi)(zhi)不同分為(wei)高(gao)(gao)溫熔融鹽鋰(li)(li)電(dian)(dian)(dian)(dian)池、有機電(dian)(dian)(dian)(dian)解質(zhi)(zhi)鋰(li)(li)電(dian)(dian)(dian)(dian)池、無機非水(shui)電(dian)(dian)(dian)(dian)解質(zhi)(zhi)鋰(li)(li)電(dian)(dian)(dian)(dian)池、固體(ti)電(dian)(dian)(dian)(dian)解質(zhi)(zhi)鋰(li)(li)電(dian)(dian)(dian)(dian)池、鋰(li)(li)水(shui)電(dian)(dian)(dian)(dian)池這幾(ji)種類型。鋰(li)(li)電(dian)(dian)(dian)(dian)池的(de)優點(dian)是(shi)單體(ti)電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)壓(ya)高(gao)(gao),比能量大,儲存壽(shou)命長(可達10年),高(gao)(gao)低溫性(xing)能好,可在-40~150℃使(shi)用。缺點(dian)是(shi)價格(ge)昂(ang)貴,安(an)全性(xing)不高(gao)(gao)。另外電(dian)(dian)(dian)(dian)壓(ya)滯后和安(an)全問題尚待改善。
廢電池有什么危害
廢舊電池中的(de)金屬汞能溶解于脂肪(fang),引發動(dong)物中樞(shu)神(shen)經(jing)疾病,致畸、致變(bian)、致癌(ai)甚至(zhi)死亡。鎘使骨質軟化(hua)、骨骼變(bian)形(xing),嚴重時形(xing)成自然骨折,以致死亡。鋅的(de)鹽類(lei)使蛋(dan)白質沉淀,對皮膚黏膜(mo)有刺激作用。鉛主要是(shi)導致貧血(xue)、神(shen)經(jing)功(gong)能失調和腎損傷,抑制(zhi)血(xue)紅蛋(dan)白的(de)合成代(dai)謝。鎳(nie)溶解于血(xue)液,會(hui)引起(qi)血(xue)管變(bian)異。錳會(hui)引起(qi)神(shen)經(jing)性功(gong)能障礙,綜合性功(gong)能紊亂,較重者出現精(jing)神(shen)癥狀。
