Positive electrode material for noaqueous secondary batteries, and nonaqueous secondary batteries using same
Abstract:
A positive electrode material for nonaqueous secondary batteries includes lithium transition metal composite oxide particles containing at least one of cobalt and nickel; and titanium silicide particles. The lithium transition metal composite oxide particles have a layer structure. The lithium transition metal composite oxide particles and the titanium silicide particles are present as particles substantially independent from each other. The titanium silicide particles have an average particle diameter of 4.0 μm or less. The titanium silicide particles are contained at a content ratio of titanium of 1.2 mol % or less with respect to the lithium transition metal composite oxide particles.
