Hard carbon material was extracted from an expired composite donkey-hide gelatin pulp via hydrothermal carbonization pelletizing and subsequent pyrolysis reaction. The corresponding micro-morphology, element composition, structure and Na-storage performances were investigated. The results show that the obtained carbon material manifests a smooth microsphere-like morphology with the mean diameter of 4.3 μm, and N and S elements evenly distribute in carbon micro-spheres with a low degree of graphitization. The reversible discharge specific capacities are 225 and 180 mAh/g at 0.5 and 1.0 A/g for 500 cycles, respectively, and the reversible discharge specific capacity remains 108 mAh/g even at 2.0 A/g for 1 000 cycles, indicating the electrochemical Na-storage cycling performances at the large current density. The results could facilitate to promote the development of the circular economy mode of expired waste medicine and the green energy.
