Method for producing electrode for alkali batteries

Abstract

An active material slurry obtained by a mixing a powder of the active material with a binder and a solvent for the binder is heated to a predetermined temperature inside a slurry reservoir and the heated active material slurry is coated and adhered to an electrically conductive core body The resulting body is then fed inside a drying furnace to dry the coated and adhered active material slurry by heating, and is rolled to a predetermined thickness by passing it through a pair of rolling rolls thereby obtaining an electrode for alkaline batteries comprising an active material layer on the both sides of the electrically conductive core body On drying the active material slurry that is coated and adhered to the electrically conductive core body the transfer of the binder inside the active material slurry is suppressed, such that the decrease in the amount of the binder inside the active material layer in the vicinity of the electrically conductive core body is prevented from occurring. Thus is obtained an electrode for alkaline batteries improved in adhesion strength.
