▎ 摘　　要

NOVELTY - Constructing surface coating layer based on metal-organic network framework material in situ involves mixing core particle, metal salt and metal complexing agent in polar solvent, and reacting to prepare coated particles with core-shell structure having core particle as core and metal-organic network framework material as shell. USE - The method is used for constructing surface coating layer based on metal-organic network framework material in situ. ADVANTAGE - The anode material can inhibit side reaction of electrode material itself and electrolyte, reduces generation of surface solid electrolyte interphase (SEI), surface film impedance and charge transfer impedance, improves reaction dynamics process of lithium ion and cycle stability and multiplying power performance, inhibits dissolution of transition metal ion, and relieves collapse of lattice structure in electrode material circulation process.
