Claim:
1. An electrode material, comprising: electrode active material particles and a carbonaceous film provided on surfaces of the electrode active material particles, wherein the electrode active material particles having the carbonaceous film provided thereon form an electrode material having a particulate shape; wherein an average of discharge capacity ratios between a 3C discharge capacity at −10° C. of a single particle of the electrode material and a 1C discharge capacity at −10° C. of a single particle of the electrode material is 0.50 or more, an XRD (CuKα ray source) peak of the (002) plane derived from graphene layers in the carbonaceous film is 2Θ=25.7° or less, and an average of plane intervals between (002) planes in the graphene layers is 0.3466 nm or more.
