Abstract: Three-dimensional (3D) porous carbon materials are successfully prepared by molten salt zinc-thermal method using sucrose as precursor and used as anode materials for potassium ion batteries. The prepared 3D porous carbon has a large number of interconnected channels, which can effectively alleviate the volume effect of the electrode during the charge-discharge cycling process, improve the infiltration of electrolyte to the electrode, shorten the diffusion path of K+. Therefore, it shows excellent cycle stability and rate performance. 3D porous carbon electrode delivers the specific capacity of 174.6 mAh·g-1 after 2 500 cycles at current density of 0.5 A·g-1 and 170 mAh·g-1 at a high rate of 4.4 A·g-1.
