電池型號尺寸一般是多少
電(dian)池型(xing)號(hao)尺(chi)寸有很多,包括一號(hao)二號(hao)五號(hao)七(qi)號(hao)等等,其(qi)中(zhong)5號(hao)電(dian)池和7號(hao)電(dian)池是生(sheng)活中(zhong)最常見(jian)的兩種電(dian)池。5號(hao)電(dian)池高49.0,直(zhi)徑14.0,一般用(yong)(yong)于電(dian)子玩具或數碼設備(bei)。7號(hao)電(dian)池高44.0,直(zhi)徑10.0,一般用(yong)(yong)戶遙控器。
常用電池的類型有哪些
1、干電池
干電(dian)(dian)池(chi)(chi)也叫錳(meng)鋅(xin)電(dian)(dian)池(chi)(chi),所謂(wei)干電(dian)(dian)池(chi)(chi)是相對(dui)于伏打電(dian)(dian)池(chi)(chi)而言(yan),所謂(wei)錳(meng)鋅(xin)是指其(qi)原材料(liao)。針(zhen)對(dui)其(qi)它(ta)材料(liao)的干電(dian)(dian)池(chi)(chi)如氧化銀電(dian)(dian)池(chi)(chi),鎳鎘電(dian)(dian)池(chi)(chi)而言(yan)。錳(meng)鋅(xin)電(dian)(dian)池(chi)(chi)的電(dian)(dian)壓是15V。干電(dian)(dian)池(chi)(chi)是消耗(hao)化學(xue)原料(liao)產(chan)生(sheng)電(dian)(dian)能(neng)的,它(ta)的電(dian)(dian)壓不(bu)高,所能(neng)產(chan)生(sheng)的持續電(dian)(dian)流不(bu)能(neng)超過1安培,因此它(ta)在一些小電(dian)(dian)器中(zhong)使用率較高。
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于數碼(ma)設(she)備。
3、鋰電池
鋰(li)(li)電(dian)(dian)(dian)池(chi)是(shi)指以鋰(li)(li)為負極的(de)電(dian)(dian)(dian)池(chi)。按所用電(dian)(dian)(dian)解(jie)(jie)質不同(tong)分為高溫熔(rong)融鹽鋰(li)(li)電(dian)(dian)(dian)池(chi)、有機電(dian)(dian)(dian)解(jie)(jie)質鋰(li)(li)電(dian)(dian)(dian)池(chi)、無機非水電(dian)(dian)(dian)解(jie)(jie)質鋰(li)(li)電(dian)(dian)(dian)池(chi)、固體電(dian)(dian)(dian)解(jie)(jie)質鋰(li)(li)電(dian)(dian)(dian)池(chi)、鋰(li)(li)水電(dian)(dian)(dian)池(chi)這幾種類型。鋰(li)(li)電(dian)(dian)(dian)池(chi)的(de)優(you)點是(shi)單體電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓高,比能量(liang)大,儲存壽(shou)命長(可達10年(nian)),高低溫性能好,可在(zai)-40~150℃使用。缺點是(shi)價格昂貴,安(an)全性不高。另(ling)外電(dian)(dian)(dian)壓滯(zhi)后(hou)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(shu)汞能(neng)溶(rong)解于脂(zhi)肪(fang),引(yin)發動物中樞神經(jing)疾病,致(zhi)(zhi)畸、致(zhi)(zhi)變、致(zhi)(zhi)癌甚至(zhi)死亡。鎘使骨(gu)(gu)質(zhi)軟化、骨(gu)(gu)骼變形,嚴重時(shi)形成(cheng)自然骨(gu)(gu)折,以致(zhi)(zhi)死亡。鋅的(de)鹽類使蛋白質(zhi)沉淀,對皮膚黏(nian)膜有刺(ci)激(ji)作(zuo)用。鉛主要(yao)是導致(zhi)(zhi)貧血、神經(jing)功(gong)能(neng)失調和腎損傷,抑制血紅蛋白的(de)合成(cheng)代(dai)謝(xie)。鎳溶(rong)解于血液,會引(yin)起血管變異。錳會引(yin)起神經(jing)性功(gong)能(neng)障礙,綜合性功(gong)能(neng)紊亂,較重者出現精神癥狀。
