電池行業簡介

電池型號尺寸一般是多少

電(dian)池(chi)型號(hao)尺寸有很多，包括(kuo)一(yi)號(hao)二號(hao)五號(hao)七號(hao)等(deng)等(deng)，其中(zhong)5號(hao)電(dian)池(chi)和(he)7號(hao)電(dian)池(chi)是生(sheng)活中(zhong)最(zui)常見的(de)兩(liang)種電(dian)池(chi)。5號(hao)電(dian)池(chi)高(gao)49.0，直(zhi)徑(jing)14.0，一(yi)般用(yong)(yong)于(yu)電(dian)子玩具或數碼設備。7號(hao)電(dian)池(chi)高(gao)44.0，直(zhi)徑(jing)10.0，一(yi)般用(yong)(yong)戶遙(yao)控器。

常用電池的類型有哪些

1、干電池

干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)也叫錳鋅電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，所謂干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是(shi)(shi)相對(dui)于(yu)伏(fu)打電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)而言，所謂錳鋅是(shi)(shi)指其原(yuan)材料(liao)(liao)。針對(dui)其它(ta)材料(liao)(liao)的(de)(de)干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)如氧化銀電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，鎳鎘電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)而言。錳鋅電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)壓是(shi)(shi)15V。干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是(shi)(shi)消耗化學原(yuan)料(liao)(liao)產生(sheng)電(dian)(dian)(dian)(dian)能(neng)的(de)(de)，它(ta)的(de)(de)電(dian)(dian)(dian)(dian)壓不高，所能(neng)產生(sheng)的(de)(de)持續電(dian)(dian)(dian)(dian)流不能(neng)超過1安培(pei)，因此(ci)它(ta)在一(yi)些(xie)小電(dian)(dian)(dian)(dian)器中使用率較(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(shu)碼設備。

3、鋰電池

鋰(li)電(dian)(dian)(dian)池(chi)(chi)是(shi)(shi)指以鋰(li)為負極(ji)的(de)電(dian)(dian)(dian)池(chi)(chi)。按所用電(dian)(dian)(dian)解質(zhi)不同(tong)分為高(gao)溫熔(rong)融鹽鋰(li)電(dian)(dian)(dian)池(chi)(chi)、有機電(dian)(dian)(dian)解質(zhi)鋰(li)電(dian)(dian)(dian)池(chi)(chi)、無機非水(shui)電(dian)(dian)(dian)解質(zhi)鋰(li)電(dian)(dian)(dian)池(chi)(chi)、固體電(dian)(dian)(dian)解質(zhi)鋰(li)電(dian)(dian)(dian)池(chi)(chi)、鋰(li)水(shui)電(dian)(dian)(dian)池(chi)(chi)這幾種類型。鋰(li)電(dian)(dian)(dian)池(chi)(chi)的(de)優點是(shi)(shi)單體電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)壓高(gao)，比能量大，儲存壽命長（可達10年），高(gao)低(di)溫性(xing)能好，可在-40～150℃使用。缺點是(shi)(shi)價格昂貴，安(an)全性(xing)不高(gao)。另外電(dian)(dian)(dian)壓滯后和(he)安(an)全問題尚待改(gai)善。

廢電池有什么危害

廢舊電池中的金屬汞能溶解于脂肪，引(yin)發(fa)動物中樞神經(jing)(jing)疾病，致(zhi)畸、致(zhi)變(bian)、致(zhi)癌甚至死(si)亡(wang)。鎘使(shi)骨質軟(ruan)化、骨骼變(bian)形，嚴重(zhong)(zhong)時形成自然(ran)骨折，以致(zhi)死(si)亡(wang)。鋅(xin)的鹽(yan)類使(shi)蛋(dan)白質沉淀(dian)，對(dui)皮(pi)膚(fu)黏膜有刺激作用。鉛主要是導致(zhi)貧血、神經(jing)(jing)功能失調(diao)和腎損(sun)傷，抑制血紅蛋(dan)白的合成代謝。鎳溶解于血液，會引(yin)起血管(guan)變(bian)異。錳(meng)會引(yin)起神經(jing)(jing)性功能障礙，綜(zong)合性功能紊(wen)亂，較(jiao)重(zhong)(zhong)者出現精神癥狀。
