▎ 摘　　要

NOVELTY - Pre-lithiation negative electrode has electrode film, which is solvent-free film-like negative electrode material composed of negative electrode active material, lithium-frame carbon composite material, binder and optional conductive agent. The lithium-frame carbon composite material is a particulate material composed of a carbon-based porous microsphere material having pores with a pore diameter of 1-100 nanometer and metallic lithium present in the pores and on the surface of the carbon-based porous microsphere material. The particle size D50 of the particulate material is 5-20 microm. The content of the lithium-frame carbon composite material is 0.5-20% based on the total mass of the electrode film in terms of mass percentage, and is uniform in the entire electrode film dispersion. The metal current collector, where the electrode film is bonded to the metal current collector by conductive glue. USE - Pre-lithiation negative electrode used in lithium ion battery or super capacitor (claimed). ADVANTAGE - The electrode has effectively improves the first effect problem of the silicon-carbon negative electrode lithium battery, which helps to improve the specific capacity and cycle life of the battery and increase the energy density of the supercapacitor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the pre-lithiated negative electrode, which involves: a).performing tn the absence of solvent;b).using high shear force to mix and disperse negative electrode active material, lithium-frame carbon composite material particle, binder and optional conductive agent;c).extruding;d).calendering the obtained mixture at a high temperature into a film-like material with a certain thickness;e).bonding the obtained film-like material to the current collector through pressure compounding to obtain pre-lithiated negative electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of steps of method execution.
