This nickel connection piece 4 is inserted into a connection groove provided on the terminal 2 and fastened by fixing it with a bolt or the like.

여기서 양극판(3)은 과산화납(PbO2)으로 이루어지고 음극판(5)은 해면상납 (Pb)으로 이루어지며 그 사이에는 전해액으로서 황산이 형성된다.Here, the positive electrode plate 3 is made of lead peroxide (PbO 2 ), the negative electrode plate 5 is made of spongy phase lead (Pb), and sulfuric acid is formed as an electrolyte therebetween.

상기에서, 니켈 연결편(4)상에 형성된 백금(Pt)은 산화작용에 필요한 활성화에너지를 낮추는 촉매역할을 함으로써 상기 양극판(3)과 음극판(5)의 충전시 발생하는 수소가 산소와 보다 용이하게 결합할 수 있도록 돕게 한다.In the above, the platinum (Pt) formed on the nickel connecting piece (4) serves as a catalyst for lowering the activation energy required for the oxidation process, so that hydrogen generated during the charging of the positive electrode plate 3 and the negative electrode plate 5 more easily with oxygen.
