N2 - A nanoreactor-structured MoSSe@NC heterostructure was constructed via defect engineering and carbon intercalation, simultaneously achieving phase transition suppression and enhanced ion transport. Selenium-induced lattice disorder and carbon layer confinement synergistically inhibit the 1T–2H phase transition and buffer structural strain during cycling. The designed heterostructure exhibits high capacity, excellent rate performance, and long-term cycling stability, offering a generalizable strategy for high-performance potassium-ion battery anodes.
