Phosphorus doping induced the co-construction of sulfur vacancies and heterojunctions in tin disulfide as a durable anode for lithium/sodium-ion batteries

A tin-based sulfide composite with heterojunctions and sulfur vacancies induced by phosphorus doping was successfully synthesized. The obtained SnS 2− x P x /RGO electrodes exhibit superior high-rate, long-term cycling stability for both LIBs and SIBs.
