▎ 摘　　要

NOVELTY - A negative electrode (10) comprises an active layer (12) and a composite layer (14) arranged on the active layer. The composite layer comprises lithiophilic nanoparticles, metal nanoparticles and a binder. The binding energy ( Delta E) of the lithiophilic nanoparticles with lithium is -2.5 eV or less. The metal nanoparticles have a standard Gibbs free energy of reaction ( Delta rG) of less than 0. The weight ratio of the lithiophilic nanoparticles to the metal nanoparticles is 1:1-8:1, and the binder contains 10-25 wt.% with respect to the total weight of the lithiophilic nanoparticles and the metal nanoparticles. USE - Negative electrode used in metal-ion battery e.g. lithium ion battery (claimed). ADVANTAGE - The negative electrode has improved efficiency and improves life cycle of the battery, reduces the reversible capacity loss and has high internal impedance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a lithium ion battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the negative electrode.
