ACTIVE MATERIAL FOR ANODE OF SECONDARY CELL AND METHOD FOR PRODUCTION THEREOF AND NON-AQUEOUS ELECTROLYTE SECONDARY CELL, AND RECYCLED ELECTRONIC FUNCTIONAL MATERIAL AND METHOD FOR RECYCLING ELECTRONIC FUNCTIONAL MATERIAL

摘要

Positive electrode active material for nonaqueous electrolytic solution secondary batteries is made of a metal oxide. A content of coarse particles, of which particles sizes are 600% or more with respect to an average particle size of the metal oxide, is 1% or less by volume, and a content of high density particles, of which densities are 150% or more with respect to an average density of the metal oxide, is 1000 ppm or less. By using the positive electrode active material, battery characteristics and a manufacturing yield may be improved.
