METAL THREE-DIMENSIONAL, MESH-LIKE POROUS BODY FOR COLLECTORS, ELECTRODE, AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

Provided are a current collector, an electrode, and a nonaqueous electrolyte secondary battery, each of which capable of reducing internal resistance and producing cost. More specifically, provided are: a three-dimensional network metal porous body for a current collector, comprising a sheet-shaped three-dimensional network metal porous body, wherein a degree of porosity of the sheet-shaped three-dimensional network metal porous body is 90% or more and 98% or less, and a 30%-cumulative pore diameter (D30) of the sheet-shaped three-dimensional network metal porous body calculated from a fine pore diameter measurement conducted by a bubble point method is 20 μm or more and 100 μm or less; an electrode using the three-dimensional network metal porous body; and a nonaqueous electrolyte secondary battery including the electrode.
