閥控鉛酸蓄電池發(fā)展概況

摘要：閥控（有氣體復(fù)合功能）鉛酸蓄電池是一種二次電池，在正常條件下是密封的，但是當(dāng)內(nèi)壓超過(guò)預(yù)定值時(shí)有一個(gè)能讓氣體析出的裝置。這種蓄電池正常時(shí)不能添加電解液。在這種式樣的蓄電池中，電解液是不流動(dòng)的。本文綜述閥控鉛酸蓄電池的發(fā)展史和一些技術(shù)問(wèn)題。 敘詞：閥控鉛酸蓄電池 膠體式閥控鉛蓄電池 貧液式閥控鉛蓄電池 膠體和吸液性隔板混合式閥控鉛蓄電池 硅粉閥控鉛蓄電池 Abstract：Valve-regulated(with gas recombination)lead-acid(VRLA)battery is a secondary battery wich is closed under normal conditions but wich has an arrangement wich allows the escape of gas if the internal pressure exceeds a predetermined value.The battery cannot normally receive an addition of electrolyte.In this type of battery,the electrolyte is immobilized.This paper reviews the history of development of VRLA batteries,and technical problems.
