Electrode material, electrode and lithium ion battery

Abstract

An electrode material of the invention includes an agglomerate formed by agglomerating carbonaceous coated electrode active material particles obtained by forming a carbonaceous coat on surfaces of electrode active material particles at a coating rate of 80% or more, and the carbonaceous coated electrode active material particles include first carbonaceous coated electrode active material particles on which a carbonaceous coat having a film thickness in a range of 0.1 nm to 3.0 nm and an average film thickness in a range of 1.0 nm to 2.0 nm is formed and second carbonaceous coated electrode active material particles on which a carbonaceous coat having a film thickness in a range of 1.0 nm to 10.0 nm and an average film thickness in a range of more than 2.0 nm to 7.0 nm is formed.
