ELECTRODE MATERIAL |
| 摘要 |
An electrode material includes an aggregate which is formed by aggregating electrode active material particles having a carbonaceous film forced on the surface thereof, in which a volume density of the aggregate is 50% by volume or more and 80% by volume or less of the volume density of a solid body which has the same external appearance as the aggregate, a coverage ratio of the carbonaceous film with respect to the surface of the electrode active material particles is 80% or more, and an average thickness of the carbonaceous film is 1.0 nm or more and 7.0 nm or less. |
