Abstract

The purpose of the present invention is to provide a nonaqueous electrolyte battery having excellent lifespan characteristics and/or excellent safety, which are essential in practice. The basic inorganic particles for a nonaqueous electrolyte battery according to the present invention include basic inorganic particles, wherein a hydrophilicity parameter A for the basic inorganic particles satisfies the expression: 0.45≤A(BET1/BET2)≤2.0. In the expression, BET1 represents the specific surface area of the basic inorganic particles calculated from an adsorption isotherm which is measured through adsorption of water vapor to the basic inorganic particles by a BET method. BET2 represents the specific surface area of the basic inorganic particles calculated from an adsorption isotherm which is measured through adsorption of nitrogen to the basic inorganic particles by a BET method.
