{Abstract}: There is an ever-increasing demand for rechargeable batteries with fast charging, long cycling, high safety, and low cost in new energy storage systems. Herein, a heterogeneous architecture composed of MoS2-coupled carbon nanosheets encapsulated on sodium titanate nanowires is developed and demonstrated as an advanced anode for sodium-ion batteries (SIBs). Owing to the synergistic effects of ultrastable substrate of 1D sodium titanate (NTO) nanowires, high-capacity promoter of 2D MoS2 nanosheets as well as the 2D conductive carbon matrix, the resulting 1D/2D-2D hybrid demonstrates excellent high-rate capacity and super-durable cyclability, delivering a stable capacity of up to 425.5 mAh g-1 at 200 mA g-1. Even at an ultrafast charging/discharging process within 80 s, the capacity can be maintained at 201 mAh g-1 after 16 000 cycles with only 0.0012% capacity loss per cycle, one of the best high-rate capacities and cyclabilities for NTO-based hybrid composites. The present work highlights the designing protocol of hierarchical nanoarchitectures with stable substrate and high-capacity electrodes for next-generation energy storage applications.
