CURRENT COLLECTOR FOR NONAQUEOUS ELECTROLYTE BATTERY, ELECTRODE FOR NONAQUEOUS ELECTROLYTE BATTERY, AND NONAQUEOUS ELECTROLYTE BATTERY |
摘要 |
A current collector for a nonaqueous electrolyte battery, in which oxygen content in the surface of an aluminum porous body is low. The current collector is made of an aluminum porous body. The content of oxygen in an aluminum porous body surface is 3.1% by mass or less. The aluminum porous body includes an aluminum alloy containing at least one Cr, Mn and transition metal elements. The aluminum porous body can be prepared by a method in which, after an aluminum alloy layer is formed on the surface of a resin of a resin body having continuous pores, the resin body is heated to a temperature of the melting point of the aluminum alloy or less to thermally decompose the resin body while applying a potential lower than the standard electrode potential of aluminum to the aluminum alloy layer with the resin body dipped in a molten salt.
