US 2006/0222953 A1 · Nonaqueous electrolyte battery

Abstract

A nonaqueous electrolyte battery wherein the per-volume capacity of positive electrode active material layer can be increased over that exhibited in the use of carbon as a conducting material. This nonaqueous electrolyte battery comprises positive electrode (1) containing a positive electrode active material layer, negative electrode (2) containing a negative electrode active material layer, nonaqueous electrolyte (5) and a conducting material contained in the positive electrode active material layer and constituted of at least one non-carbon material selected from the group consisting of nitrides, carbides and borides, which conducting material is in the form of particles of 0.2 to 5 μm average diameter easily dispersed in the positive electrode active material layer.
