▎ 摘 要
NOVELTY - Electrode material comprises 65-97.5 pts. wt. electrode active material, 1-15 pts. wt. agglomerant agent, 1-15 pts. wt. conductive agent and 0.5-5 pts. wt. carbon additive; where the carbon additive is provided with three-dimensional through hole, and the pore diameter of the hole is 50-300 nm. USE - Electrode material used in electrode sheet of energy storage device (claimed). ADVANTAGE - The material improves the capacity of the electrode active material, and improves the energy density of the energy storage device. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for An electrode active film; A preparation method of electrode active film; An electrode sheet; A preparation method of electrode sheet; and An energy storage device.
