Abstract Long-term stability and high-rate capability have been the major challenges of sodium-ion batteries. Layered electroactive materials with mechanically robust, chemically stable, electrically ironically conductive networks can effectively address these issues. Herein we successfully directed carbon nanofibers to vertically penetrate through graphene sheets, constructing robust nanofiber interpenetrated architecture. Molybdenum disulfide nanoflakes are then grown in situ alongside...
