ABSTRACT:
A novel process is provided for producing an improved electrode for an alkaline battery comprising the steps of adding an unsintered fluorocarbon resin powder to an active material powder and intimately mixing them together, applying a shear force to said mixture to thereby form agglomerates capable of retaining said active material powder in a network structure resulting from a fiber-formation of said fluorocarbon resin powder, adding an aqueous solution of a paste to said agglomerates, kneading them to mutually bind said agglomerates and thus forming a rubbery mass converting said rubbery mass into a sheet and attaching the sheet thus formed onto an electrically conductive core. The process provides an electrode having excellent reactivity and results in improved production efficiency.
