Production method for aluminum porous body, aluminum porous body, current collector, electrode, and electrochemical device

Abstract

A production method for an aluminum porous body includes a step of producing a resin structure by forming an aluminum film on a surface of a resin base having a three-dimensional network structure by molten salt electrolytic plating, a step of removing moisture from the resin structure, and a step of removing the base by heat-treating the resin structure from which moisture has been removed. In the step of removing moisture from the resin structure, the resin structure is preferably heat-treated at a temperature of 50° C. or higher and 300° C. or lower. In the step of removing the base, the resin structure is preferably heat-treated at a temperature equal to or higher than 370° C. and lower than the melting point of aluminum.
