Pore structure engineering in peat-derived hard carbon <i>via</i> confined carbonization for boosted sodium storage
The electrochemical Na<sup>+</sup> 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<sup>-1</sup> at a current density of 30 mA g<sup>-1</sup> with an initial coulombic efficiency of 74.71%.
