電池行業簡介

電池型號尺寸一般是多少

電(dian)(dian)池(chi)型號(hao)尺(chi)寸有很(hen)多，包括一(yi)號(hao)二(er)號(hao)五(wu)號(hao)七號(hao)等等，其(qi)中5號(hao)電(dian)(dian)池(chi)和7號(hao)電(dian)(dian)池(chi)是生(sheng)活中最常見的(de)兩種(zhong)電(dian)(dian)池(chi)。5號(hao)電(dian)(dian)池(chi)高49.0，直(zhi)徑(jing)(jing)14.0，一(yi)般用于電(dian)(dian)子玩具或數碼設備。7號(hao)電(dian)(dian)池(chi)高44.0，直(zhi)徑(jing)(jing)10.0，一(yi)般用戶(hu)遙控器。

常用電池的類型有哪些

1、干電池

干電(dian)(dian)(dian)(dian)池(chi)也叫(jiao)錳(meng)鋅(xin)(xin)電(dian)(dian)(dian)(dian)池(chi)，所謂(wei)干電(dian)(dian)(dian)(dian)池(chi)是(shi)相對于伏打電(dian)(dian)(dian)(dian)池(chi)而言(yan)，所謂(wei)錳(meng)鋅(xin)(xin)是(shi)指其(qi)原(yuan)材料(liao)。針(zhen)對其(qi)它(ta)材料(liao)的(de)干電(dian)(dian)(dian)(dian)池(chi)如氧化銀電(dian)(dian)(dian)(dian)池(chi)，鎳鎘電(dian)(dian)(dian)(dian)池(chi)而言(yan)。錳(meng)鋅(xin)(xin)電(dian)(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)(dian)壓是(shi)15V。干電(dian)(dian)(dian)(dian)池(chi)是(shi)消耗化學(xue)原(yuan)料(liao)產生電(dian)(dian)(dian)(dian)能的(de)，它(ta)的(de)電(dian)(dian)(dian)(dian)壓不(bu)(bu)高，所能產生的(de)持續電(dian)(dian)(dian)(dian)流(liu)不(bu)(bu)能超過(guo)1安(an)培，因此(ci)它(ta)在一些小電(dian)(dian)(dian)(dian)器中(zhong)使用(yong)率(lv)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(shu)碼設(she)備(bei)。

3、鋰電池

鋰(li)(li)(li)(li)電(dian)(dian)(dian)池(chi)(chi)是指以(yi)鋰(li)(li)(li)(li)為負極的電(dian)(dian)(dian)池(chi)(chi)。按所用(yong)電(dian)(dian)(dian)解(jie)質不(bu)同分為高溫熔(rong)融鹽鋰(li)(li)(li)(li)電(dian)(dian)(dian)池(chi)(chi)、有(you)機電(dian)(dian)(dian)解(jie)質鋰(li)(li)(li)(li)電(dian)(dian)(dian)池(chi)(chi)、無機非水電(dian)(dian)(dian)解(jie)質鋰(li)(li)(li)(li)電(dian)(dian)(dian)池(chi)(chi)、固(gu)體電(dian)(dian)(dian)解(jie)質鋰(li)(li)(li)(li)電(dian)(dian)(dian)池(chi)(chi)、鋰(li)(li)(li)(li)水電(dian)(dian)(dian)池(chi)(chi)這幾種類(lei)型。鋰(li)(li)(li)(li)電(dian)(dian)(dian)池(chi)(chi)的優點是單體電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)壓(ya)高，比(bi)能量大(da)，儲存壽命長（可(ke)達10年），高低(di)溫性能好，可(ke)在-40～150℃使用(yong)。缺(que)點是價格昂貴，安全性不(bu)高。另外電(dian)(dian)(dian)壓(ya)滯后和(he)安全問題尚待(dai)改善。

廢電池有什么危害

廢(fei)舊電池中的金屬(shu)汞(gong)能溶(rong)解于脂(zhi)肪，引(yin)發動物中樞神(shen)(shen)經(jing)疾(ji)病，致畸、致變、致癌(ai)甚至死亡。鎘使骨質軟化、骨骼變形，嚴重時形成(cheng)自然骨折，以致死亡。鋅的鹽類使蛋白質沉淀，對皮膚黏(nian)膜有刺(ci)激作用。鉛(qian)主(zhu)要是導致貧血(xue)、神(shen)(shen)經(jing)功能失調和腎損傷，抑制血(xue)紅蛋白的合成(cheng)代謝。鎳溶(rong)解于血(xue)液(ye)，會(hui)引(yin)起血(xue)管(guan)變異。錳會(hui)引(yin)起神(shen)(shen)經(jing)性功能障礙，綜合性功能紊亂，較重者(zhe)出現精神(shen)(shen)癥狀。
