▎ 摘　　要

NOVELTY - Preparing a carbon/Prussian blue composite material, comprises preparing the carbon material, chelating agent and transition metal salt into the first mixture dispersion, performing the first hydrothermal reaction to obtain the carbon-transition metal composite precursor, preparing the alkali metal-ferrocyanide and carbon-transition metal composite precursor into a second mixture dispersion, performing a second hydrothermal reaction, and then performing post-treatment to obtain the final product. USE - The carbon/Prussian blue composite material is useful in the field of battery. ADVANTAGE - The composite material: is suitable for mass production; has excellent conductivity, cyclability and stability; and the method reduce the structural defects of ferrocyanide vacancies and crystal water that are easy to appear in the synthesizing process. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a carbon/Prussian blue composite material prepared by the above-mentioned method. a anode material for secondary battery, comprising carbon/Prussian blue composite material; and a secondary battery, comprising cathode current collector, cathode material, an electrolyte, a diaphragm, anode material, anode current collector, where the anode material is the anode material of the secondary battery.
