電池型號尺寸一般是多少
電(dian)池型(xing)號尺寸(cun)有很多,包(bao)括一號二號五號七(qi)號等等,其中(zhong)5號電(dian)池和(he)7號電(dian)池是生(sheng)活中(zhong)最(zui)常見(jian)的兩種電(dian)池。5號電(dian)池高49.0,直徑14.0,一般用(yong)(yong)于電(dian)子玩(wan)具或數碼設備(bei)。7號電(dian)池高44.0,直徑10.0,一般用(yong)(yong)戶遙(yao)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(jiao)錳鋅(xin)電(dian)(dian)池(chi)(chi),所(suo)謂干電(dian)(dian)池(chi)(chi)是相對(dui)于伏(fu)打電(dian)(dian)池(chi)(chi)而言,所(suo)謂錳鋅(xin)是指其原材料(liao)。針對(dui)其它(ta)材料(liao)的干電(dian)(dian)池(chi)(chi)如(ru)氧化(hua)銀(yin)電(dian)(dian)池(chi)(chi),鎳(nie)鎘電(dian)(dian)池(chi)(chi)而言。錳鋅(xin)電(dian)(dian)池(chi)(chi)的電(dian)(dian)壓(ya)是15V。干電(dian)(dian)池(chi)(chi)是消耗化(hua)學(xue)原料(liao)產生電(dian)(dian)能(neng)的,它(ta)的電(dian)(dian)壓(ya)不高(gao),所(suo)能(neng)產生的持續電(dian)(dian)流不能(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(gao)。
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(neng)用于數碼(ma)設備(bei)。
3、鋰電池
鋰電(dian)(dian)(dian)池(chi)是指以(yi)鋰為負極的電(dian)(dian)(dian)池(chi)。按所(suo)用(yong)電(dian)(dian)(dian)解(jie)(jie)(jie)質(zhi)不同分(fen)為高(gao)(gao)溫熔融鹽鋰電(dian)(dian)(dian)池(chi)、有機(ji)電(dian)(dian)(dian)解(jie)(jie)(jie)質(zhi)鋰電(dian)(dian)(dian)池(chi)、無機(ji)非水電(dian)(dian)(dian)解(jie)(jie)(jie)質(zhi)鋰電(dian)(dian)(dian)池(chi)、固體電(dian)(dian)(dian)解(jie)(jie)(jie)質(zhi)鋰電(dian)(dian)(dian)池(chi)、鋰水電(dian)(dian)(dian)池(chi)這(zhe)幾種類型。鋰電(dian)(dian)(dian)池(chi)的優點(dian)是單體電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓(ya)高(gao)(gao),比能量大(da),儲存壽(shou)命長(可達(da)10年),高(gao)(gao)低(di)溫性(xing)能好,可在(zai)-40~150℃使用(yong)。缺點(dian)是價格昂貴,安全性(xing)不高(gao)(gao)。另(ling)外電(dian)(dian)(dian)壓(ya)滯后和安全問題(ti)尚待(dai)改善。
廢電池有什么危害
廢舊電池中的金屬汞能(neng)溶(rong)解于脂肪,引發動物中樞(shu)神(shen)經疾病,致畸、致變、致癌(ai)甚至(zhi)死亡。鎘使骨質(zhi)軟化、骨骼變形,嚴重(zhong)時(shi)形成(cheng)自然骨折,以(yi)致死亡。鋅(xin)的鹽(yan)類使蛋(dan)白質(zhi)沉(chen)淀,對皮膚黏膜有刺激作用。鉛主要是導致貧血(xue)、神(shen)經功(gong)能(neng)失(shi)調(diao)和腎損傷(shang),抑制(zhi)血(xue)紅蛋(dan)白的合成(cheng)代謝。鎳(nie)溶(rong)解于血(xue)液,會引起血(xue)管變異(yi)。錳會引起神(shen)經性(xing)功(gong)能(neng)障(zhang)礙(ai),綜合性(xing)功(gong)能(neng)紊亂,較重(zhong)者出現精神(shen)癥狀。
