Abstract: PURPOSE:To obtain non-sintered type electrode, particularly a paste type electrode which has large application coefficient and capacity density and improved life span for severe charging and discharging conditions by pressurizing a conductive core material adhered with black mix of active substance with the roller having the surface including recessions and protrusions and then with the smooth surface. CONSTITUTION:After a mixed material of active substances is adhered to a conductive porous material, it is pressurized repeatedly with the roller having the surface including recessions and protrusions and thereafter with the smooth surface. For example, the both sides of core material which is obtained by nickel- plating of punching metal where holes are bored with diameter of 2mm. and center pitch of 3mm. on a iron plate in the thickness of 0.1mm. are coated with the paste for positive pole of nickel. Such core material is caused to pass through the slits and thickness after drying is set to 1.5+ or -0.05mm.. The material is then immersed into the aqueous solution of cobalt acetate. After it is dried, the material is the immersed into the aqueous solution of caustic potash to change the cobalt acetate into cobalt hydroxide. This pole plate is cut and is then applied to the roller having protrusions in cubic shape with a side of 0.2mm. and height of 0.08mm. and interval of 1mm. in order to pressurization. The plate is pressurized 3 times until it is elongated by 12% in the longitudinal direction and then it is pressurized by the smooth surface in the pressure of 1,200kg/cm<2>.
