▎ 摘　　要

NOVELTY - Pre-lithiation cathode comprises a metal current collector and an electrode film compounded on the metal current collector, the solvent-free film-shaped cathode material is cathode active substance, lithium-lithophilic framework composite material, a binder and an optional conductive cathode, where the lithium-lithophilic framework composite material is composed of a porous particle as a lithium-lithophilic framework and metal lithium filled in the pores of the porous particle; the porous particle is formed by interweaving a crystallized carbon framework whose surface is coated with an amorphous carbon layer, particle interior and surface with nano-sized pores, non-porous part of the particle surface is also covered by amorphous carbon layer, and the particle diameter D50 of the porous particle is 1-50 µm, the porosity is 15-85%, where the content of lithium-lithophilic framework composite material is 0.5-30 wt.% electrode film, and uniformly dispersed in the whole electrode film. USE - The pre-lithiation cathode is used for lithium ion battery or supercapacitor (claimed). ADVANTAGE - The method improves the first effect of the silicon-carbon cathode lithium battery, is good for improving the specific capacity and cycle life of the battery, and improves the energy density of the supercapacitor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the pre-lithiation cathode.
