▎ 摘　　要

NOVELTY - A particulate-form electrode material comprises carbonaceous film which is formed on surface of electrode active material particle which has olivine-type crystal structure in which graphene layer of carbonaceous film is randomly laminated. Electrode material bending ratio of lithium ion migration route of carbonaceous film is 1.1-100. USE - An electrode material for paste used for electrodes used in lithium ion battery (all claimed). ADVANTAGE - Reduction of voltage during high-speed charging/discharging process in low-temperature environment can be suppressed. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) paste for electrodes containing electrode material and binder; and (2) lithium ion battery which comprises positive electrode electrical power collector which has electrode material layer formed from paste for electrodes on metal foil.
