Abstract:
A method for producing an electrode for alkaline batteries, which is formed by coating and adhering a slurry of an active material comprising a powder of hydrogen absorbing alloy, a water-soluble binder, and water or purified water as a solvent for the water-soluble binder on an electrically conductive core body, said method comprising:a step of preparing a slurry of an active material by mixing the powder of hydrogen-absorbing alloy with the water-soluble binder and the solvent for the water-soluble binder; a step of heating the slurry of the active material; a step of coating and adhering slurry, in which the heated slurry is coated and adhered to the electrically conductive core body; a step of drying the electrically conductive core body to which the heated slurry is coated and adhered so as to form an electrode while the active material is being heated by the dryer; and a pressing step of rolling the electrode wherein the temperature of heating the slurry in the step of heating the slurry is lower than the temperature in the drying step.
