Electrode material, electrode and lithium ion battery

An electrode material comprising:

• an agglomerate formed by agglomerating a plurality of agglomerated particles formed by agglomerating a plurality of particles of a carbonaceous coated electrode active material having a carbonaceous coat formed on a surface,
• wherein the agglomerate is made up of hollow-structured particles and solid-structured particles,
• an average particle diameter of the agglomerate is in a range of 0.5 μm to 100 μm,
• a volume density of the agglomerate is in a range of 50% by volume to 80% by volume of the volume density of the solid agglomerate, a micropore distribution of micropores present in the agglomerate is monomodal, an average micropore diameter in the micropore distribution is 0.3 μm or less, and an N-methyl-2-pyrollidone oil absorption amount of the agglomerate is in a range of 40 g/100 g to 100 g/100 g.
