電池型號尺寸一般是多少
電(dian)(dian)池(chi)型號(hao)(hao)尺寸有很多(duo),包括一(yi)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)(dian)池(chi)和7號(hao)(hao)電(dian)(dian)池(chi)是生活中最常見的(de)兩種電(dian)(dian)池(chi)。5號(hao)(hao)電(dian)(dian)池(chi)高49.0,直(zhi)徑(jing)14.0,一(yi)般(ban)用(yong)于電(dian)(dian)子(zi)玩具或數碼(ma)設備。7號(hao)(hao)電(dian)(dian)池(chi)高44.0,直(zhi)徑(jing)10.0,一(yi)般(ban)用(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)也(ye)叫錳鋅(xin)電(dian)(dian)池(chi),所(suo)謂干電(dian)(dian)池(chi)是(shi)相對于(yu)伏(fu)打電(dian)(dian)池(chi)而言(yan)(yan),所(suo)謂錳鋅(xin)是(shi)指其原材料(liao)。針對其它材料(liao)的(de)(de)干電(dian)(dian)池(chi)如氧化銀(yin)電(dian)(dian)池(chi),鎳鎘電(dian)(dian)池(chi)而言(yan)(yan)。錳鋅(xin)電(dian)(dian)池(chi)的(de)(de)電(dian)(dian)壓是(shi)15V。干電(dian)(dian)池(chi)是(shi)消(xiao)耗化學原料(liao)產生電(dian)(dian)能的(de)(de),它的(de)(de)電(dian)(dian)壓不(bu)高(gao),所(suo)能產生的(de)(de)持續(xu)電(dian)(dian)流不(bu)能超過1安培,因此(ci)它在一些小電(dian)(dian)器中使用率(lv)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用于數(shu)碼設(she)備。
3、鋰電池
鋰(li)電(dian)(dian)(dian)池是(shi)(shi)指以鋰(li)為(wei)(wei)負(fu)極的電(dian)(dian)(dian)池。按所用電(dian)(dian)(dian)解(jie)質(zhi)不(bu)(bu)同分(fen)為(wei)(wei)高(gao)溫熔融鹽(yan)鋰(li)電(dian)(dian)(dian)池、有機電(dian)(dian)(dian)解(jie)質(zhi)鋰(li)電(dian)(dian)(dian)池、無機非(fei)水電(dian)(dian)(dian)解(jie)質(zhi)鋰(li)電(dian)(dian)(dian)池、固(gu)體電(dian)(dian)(dian)解(jie)質(zhi)鋰(li)電(dian)(dian)(dian)池、鋰(li)水電(dian)(dian)(dian)池這幾種類型。鋰(li)電(dian)(dian)(dian)池的優點是(shi)(shi)單(dan)體電(dian)(dian)(dian)池電(dian)(dian)(dian)壓(ya)高(gao),比(bi)能量大,儲存壽命長(可達(da)10年),高(gao)低溫性能好,可在-40~150℃使用。缺(que)點是(shi)(shi)價格(ge)昂(ang)貴,安(an)(an)全性不(bu)(bu)高(gao)。另外電(dian)(dian)(dian)壓(ya)滯后和安(an)(an)全問(wen)題尚(shang)待改善。
廢電池有什么危害
廢舊電池中的(de)(de)金屬汞能(neng)溶解于脂(zhi)肪,引發動物中樞(shu)神(shen)(shen)經(jing)疾病,致(zhi)(zhi)(zhi)畸、致(zhi)(zhi)(zhi)變(bian)(bian)、致(zhi)(zhi)(zhi)癌甚至(zhi)死亡(wang)。鎘使骨(gu)質軟化、骨(gu)骼變(bian)(bian)形,嚴重時(shi)形成自然骨(gu)折(zhe),以致(zhi)(zhi)(zhi)死亡(wang)。鋅(xin)的(de)(de)鹽類使蛋白質沉(chen)淀,對皮膚黏膜有刺激作用。鉛主(zhu)要是導致(zhi)(zhi)(zhi)貧血(xue)(xue)、神(shen)(shen)經(jing)功(gong)能(neng)失調和(he)腎損傷,抑制血(xue)(xue)紅蛋白的(de)(de)合成代(dai)謝(xie)。鎳溶解于血(xue)(xue)液(ye),會(hui)引起(qi)血(xue)(xue)管(guan)變(bian)(bian)異(yi)。錳會(hui)引起(qi)神(shen)(shen)經(jing)性功(gong)能(neng)障礙,綜合性功(gong)能(neng)紊亂(luan),較重者出現精(jing)神(shen)(shen)癥狀。
