▎ 摘　　要

NOVELTY - Sodium vanadium phosphate material with three-dimensional carbon framework, is claimed. The sodium vanadium phosphate material is attached to the surface of a cubic carbon framework constructed by ZIF-8 by sodium vanadium phosphate particles. A network structure formed by carbon materials is evenly distributed in the cubic carbon framework. USE - The sodium vanadium phosphate material is useful in anode sheet of sodium ion battery (all claimed). ADVANTAGE - The sodium vanadium phosphate material has ZIF8 with large surface area and nanopore diameter, excellent conductivity of CNTs and conductive carbon, which greatly enhances the electronic conductivity of sodium vanadium phosphate, and improved electrochemical performance of sodium vanadium phosphate in sodium-ion batteries. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of sodium vanadium phosphate material with three-dimensional carbon framework.
