NOVELTY - Lithium ion additive comprises lithium hydride. USE - The lithium ion additive is useful for lithium ion capacitor or lithium ion battery anode (claimed). ADVANTAGE - The additive has ultra-high theoretical specific capacity of 3350 mAh/g, can be dissolved in the ether solvent, when using it can be directly dripped on the prepared positive plate, without considering the compatibility problem of the solvent used for preparing the anode slurry. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for: (1) a anode for lithium ion capacitor or lithium ion battery comprising lithium supplement additive; (2) preparing the anode comprising (1) using homogenizing method to prepare electrode A, where the slurry of the homogenate method comprises anode active material, conductive agent, bonding agent and organic solvent, (2) dissolving the lithium supplement additive in the ether solvent to obtain the lithium supplement additive solution, (3) before assembling the full battery, coating the lithium supplement additive solution on the anode A, removing ether solvent, and compacting to obtain the anode; and (3) lithium ion capacitor or lithium ion battery, comprising a anode, a cathode and an electrolyte, where anode includes the lithium supplement additive.
