A cathode material includes crystalline nanometer-sized primary particles of a metal compound having one of olivine and NASICON structures and a particle size ranging from 10 to 500 nm, and micrometer-sized secondary particles having a particle size ranging from 1 to 50 µm. Each of the micrometer-sized secondary particles is composed of the crystalline nanometer-sized primary particles. |
