<p>Exploring a potential anode material is critical for developing efficient and long-cycling sodium-ion batteries (SIBs), where hard carbon is deemed to be in the forefront in this regard. Nevertheless, it still remains a challenge to achieve a high-performance hard carbon anode from cost‐effective carbon sources. Here, we report a bio-waste-derived hard carbon from pomegranate peels as inexpensive and sustainable alternative for SIB anode. The pomegranate peels are pyrolyzed at temperatures between 1100 and 1300&#xa0;°C to obtain the optimized hard carbon. The electrochemical performance of the hard carbons as an anode material in SIBs were investigated and the optimized pomegranate peels carbon (PGPC) heat treated at 1200&#xa0;°C exhibited the maximum reversible capacity of 253 mAh g⁻¹ at 0.05 C. The excellent electrochemical performance could be attributed to the microporous morphology of the structure facilitating the electrolyte penetration into the interior regions of the electrode and to the disordered crystal structure providing sites for additional Na-ion storage. This work emphasizes the use of bio-waste-derived carbons as an efficient and affordable anode for high-energy SIBs.</p>
