▎ 摘　　要

NOVELTY - Artificial graphite composite material coated with boron-doped solid electrolyte composite material, comprises 0.5-2 wt.% lithium borate, 1-5 wt.% solubilizer, 0.1-0.3 wt.% solid electrolytically charged electrolyte, and 0. 5-2 vol.% conductive agent and amorphous carbon, is new. USE - Artificial graphite composite material coated with boron-doped solid electrolyte composite material for lithium ion battery material used in electric vehicle. ADVANTAGE - The artificial graphite composite material has high ionic conductivity characteristics of solid electrolyte, characteristics conductivity of conductive agent electronic conductivity, and electron-ion conduction rate. The lithium borate provides sufficient lithium ions to improve the first efficiency of the material and exerts the coupling agent to form a conductive network on the coupling effect of the coating layer. The material improves the structural stability and multiplying power cycle performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of artificial graphite composite material coated by boron-doped solid electrolyte composite material.
