Title:
POSITIVE ELECTRODE ACTIVE MATERIAL, PRODUCTION METHOD THEREOF, AND NEGATIVE ELECTRODE AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2013211209
Kind Code:
A
Abstract:

To provide a method for producing a positive electrode active material for coating positive electrode active material precursor particles with carbon while reducing the positive electrode active material precursor particles.

A method for producing a positive electrode active material includes a step of calcining positive electrode active material precursor particles while exposing to a reducing gas and a hydrocarbon gas. Another method for producing a positive electrode active material includes the steps of: adding a reducing agent to the positive electrode active material precursor particles, and calcining the positive electrode active material precursor particles while exposing the positive electrode active material precursor particles to a hydrocarbon gas.
