Abstract:
The electrochemical Na+ storage properties of hard carbon prepared by direct annealing of peat are limited by its open pore structure. Here, we report a co-annealing strategy that repairs the structure within the confined mesopore space in peat, achieving a capacity of 242.5 mAh g-1 at a current density of 30 mA g-1 with an initial coulombic efficiency of 74.71%.
