Electrode material and the electrode layer using the same, cell and electrochromic devices

An electrode material consisting of at least one powder of a metallic compound powder and carbon powder, average particle size of the powder is not less 50μm or less, the electrode material activation energy E Further, it is preferable that the powder has a hopping conduction properties at room temperature (25 ° C.). Further, it is preferable that the oxygen deficiency amount of the powder is 1 × Further, it is preferable that the carrier density of the powder is 1 × According to the above configuration, it is possible to charge capacity is high and provides a high electrode material charge-discharge efficiency.
