NOVELTY - Preparing cathode material comprises (a) preparing metal organic frame material zeolitic imidazolate framework-67, (b) dissolving sodium molybdate dihydrate and L-ammonium cysteate in distilled water, stirring, adding dopamine hydrochloride, stirring for 40-60 minutes, transferring solution into autoclave and reacting at 180-210 degrees C for 20-30 hours, washing the obtained product with absolute ethanol and distilled water for twice, drying at 65 degrees C to obtain precursor, (c) placing zeolitic imidazolate framework-67 in tube furnace under carbon monoxide, performing partial carbonization at 500-600 degrees C to obtain carbon-zeolitic imidazolate framework-67 and (d) stirring and mixing carbon-zeolitic imidazolate framework-67, graphene oxide and precursor, and grinding with mortar, placing in tube furnace, calcining in nitrogen atmosphere at 800-1000 degrees C for 2 hours and cooling. USE - The method is useful for preparing cathode material for sodium ion battery. ADVANTAGE - The method: can buffer the volume change existing in the sodium storage process; plays good supporting role and exhibits excellent sodium storage performance.
