Abstract
PURPOSE: To afford uniform and sufficient etching effect to an electrode base material by beforehand heat-treating a porous electrode base material then etching the same.
CONSTITUTION: A porous electrode base material which has activated surface partially on its surface or in which stress and strain remain locally is heat-treated prior to etching. After the heat treatment, the electrode base material is immersed in a soln. of a suitable concn. such as hydrochloric acid, perchloric acid, or sulfuric acid as it is or, if necessary, after descaling, pickling, degreasing, etc., whereby it is etched. The etched electrode base material is next washed and dried according to need, and is sent to the next placing process; such as processes of coating of active material, sintering and coating.
