Electrode material and a method for producing the same, and the electrode, a secondary battery and the vehicle

By devising a method of forming the electrode material, and an object thereof is to produce a secondary battery having a large capacity. Electrode material has an active material constituting the negative electrode and the positive electrode material or the like, and a carbon-based material covered on the surface of the active material. Carbon-based material, ultrasound, the frequency 40 [kHz], the output 200 to 300 [[W] irradiation time 2 [h] ~9 [h], irradiating the aromatic organic solvents such as o- dichlorobenzene the one in which the aromatic organic solvents produced by radical reaction. With this configuration, the carbon-based material ingress throughout the crystals of the active material and (adherend), while providing excellent electrode material conductive, expansion and of the active material due to Li ion insertion and elimination reactions the structure collapse due to shrinkage can provide a stable negative electrode and the positive electrode material which suppresses.
