電池行業簡介

電池型號尺寸一般是多少

電(dian)池(chi)(chi)型號(hao)尺寸(cun)有(you)很多，包括(kuo)一號(hao)二號(hao)五號(hao)七號(hao)等等，其中5號(hao)電(dian)池(chi)(chi)和7號(hao)電(dian)池(chi)(chi)是生活中最常見的(de)兩種電(dian)池(chi)(chi)。5號(hao)電(dian)池(chi)(chi)高49.0，直徑(jing)14.0，一般用于電(dian)子玩具或(huo)數(shu)碼設備。7號(hao)電(dian)池(chi)(chi)高44.0，直徑(jing)10.0，一般用戶遙控器(qi)。

常用電池的類型有哪些

1、干電池

干(gan)電(dian)(dian)(dian)(dian)池也叫錳鋅(xin)電(dian)(dian)(dian)(dian)池，所(suo)謂(wei)干(gan)電(dian)(dian)(dian)(dian)池是相(xiang)對于伏打電(dian)(dian)(dian)(dian)池而言，所(suo)謂(wei)錳鋅(xin)是指其(qi)原材(cai)料。針對其(qi)它材(cai)料的(de)(de)干(gan)電(dian)(dian)(dian)(dian)池如氧化銀電(dian)(dian)(dian)(dian)池，鎳鎘電(dian)(dian)(dian)(dian)池而言。錳鋅(xin)電(dian)(dian)(dian)(dian)池的(de)(de)電(dian)(dian)(dian)(dian)壓是15V。干(gan)電(dian)(dian)(dian)(dian)池是消(xiao)耗化學(xue)原料產生電(dian)(dian)(dian)(dian)能(neng)(neng)(neng)的(de)(de)，它的(de)(de)電(dian)(dian)(dian)(dian)壓不(bu)高，所(suo)能(neng)(neng)(neng)產生的(de)(de)持續電(dian)(dian)(dian)(dian)流不(bu)能(neng)(neng)(neng)超(chao)過1安培，因此它在一些(xie)小電(dian)(dian)(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(yong)于數碼設(she)備。

3、鋰電池

鋰(li)電(dian)(dian)(dian)(dian)池是(shi)指以(yi)鋰(li)為負極的電(dian)(dian)(dian)(dian)池。按所用(yong)電(dian)(dian)(dian)(dian)解(jie)質不同(tong)分為高(gao)(gao)溫熔融(rong)鹽鋰(li)電(dian)(dian)(dian)(dian)池、有機(ji)電(dian)(dian)(dian)(dian)解(jie)質鋰(li)電(dian)(dian)(dian)(dian)池、無機(ji)非水電(dian)(dian)(dian)(dian)解(jie)質鋰(li)電(dian)(dian)(dian)(dian)池、固體(ti)電(dian)(dian)(dian)(dian)解(jie)質鋰(li)電(dian)(dian)(dian)(dian)池、鋰(li)水電(dian)(dian)(dian)(dian)池這(zhe)幾種(zhong)類型。鋰(li)電(dian)(dian)(dian)(dian)池的優點(dian)是(shi)單體(ti)電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)壓高(gao)(gao)，比能量(liang)大(da)，儲(chu)存(cun)壽命(ming)長（可(ke)達10年），高(gao)(gao)低溫性能好，可(ke)在-40～150℃使用(yong)。缺點(dian)是(shi)價格昂貴，安全(quan)性不高(gao)(gao)。另外電(dian)(dian)(dian)(dian)壓滯后和安全(quan)問題尚待改善。

廢電池有什么危害

廢舊電池中的(de)金屬(shu)汞能溶解(jie)于(yu)脂肪，引(yin)發動物中樞神(shen)經疾(ji)病(bing)，致畸、致變、致癌甚至(zhi)死亡。鎘(ge)使骨(gu)質軟(ruan)化、骨(gu)骼(ge)變形(xing)(xing)，嚴重時(shi)形(xing)(xing)成自然骨(gu)折，以致死亡。鋅的(de)鹽類使蛋白(bai)質沉(chen)淀，對皮(pi)膚黏膜有刺激作用。鉛主要是(shi)導致貧血、神(shen)經功能失調和腎(shen)損傷(shang)，抑制血紅蛋白(bai)的(de)合(he)成代謝。鎳溶解(jie)于(yu)血液，會引(yin)起血管變異。錳(meng)會引(yin)起神(shen)經性(xing)功能障礙，綜(zong)合(he)性(xing)功能紊亂，較重者出現精神(shen)癥狀。
