However, their practical application is hindered by slow ion diffusion kinetics and structural degradation during cycling, resulting in rapid capacity decay. To address these limitations, we developed a sulfur/selenium (S/Se) dual-anion engineering strategy that creates strong interfacial charge redistribution through S2−/Se2− synergy, thereby accelerating charge transfer kinetics and stabilizing the electrode-electrolyte interface. Using a one-step microwave-assisted synthesis (20 minutes), we successfully fabricated NiSSe nanoparticles embedded in nitrogen-doped carbon (NiSSe/N-C). The NiSSe/N-C anode delivers ultrahigh reversible capacities of 1006.2 mAh g−1 at 0.2 A g−1 and 756.4 mAh g−1 at 5 A g−1 over 3000 cycles in SIBs, while achieving 530 mAh g−1 at 0.2 A g−1 and 477 mAh g−1 at 1 A g−1 over 200 cycles in PIBs. When paired with a NaNi0.33Fe0.33Mn0.33O2 cathode in a full-cell configuration, the NiSSe/N-C anode enables 96.7% capacity retention after 200 cycles, demonstrating its practicality in pouch cells. This work highlights the dual advantages of microwave-driven rapid synthesis and multi-anion synergy for designing high-performance battery materials.
