METHOD FOR PRODUCING ELECTRODE MATERIAL FOR ALUMINUM ELECTROLYTIC CAPACITORS, AND ELECTRODE MATERIAL FOR ALUMINUM ELECTROLYTIC CAPACITORS

摘要

The present invention provides a production method that enables easy production of an electrode material for aluminum electrolytic capacitor having a high capacitance, and that enables, in particular, easy production of an electrode material for aluminum electrolytic capacitor having a high capacitance regardless of the average particle diameter (D50) of aluminum powder to be used.;Specifically, the present invention provides a method for producing an electrode material for aluminum electrolytic capacitor, comprising the steps of:
(1) a first step of forming a film of a paste composition containing powder of at least one of aluminum and an aluminum alloy, a binder resin, and a solvent on at least one surface of a substrate,(2) a second step of sintering the film, and(3) a third step of applying an etching treatment on the sintered film.
