摘要： An electrode plate group is accommodated together with liquid electrolyte in a metal case having an oval or rectangular cross section. The open end of the case is sealed by a metal sealing plate, with an insulation gasket fitted between the case and the sealing plate. The electrode plate group is constructed with a positive electrode plate and a negative electrode plate wound around with a separator interposed therebetween. Core materials of respective plates are protruded to opposite sides to form a positive electrode end face and a negative electrode end face at either end of the electrode plate group. The winding axis of the electrode plates is vertical to the open end of the case, and the positive and negative electrode end faces are respectively connected to the sealing plate and the bottom face of the case in direct or indirect surface contact therewith.
