Summary: This study reports a novel strategy for the confined growth of MoS2 nanodots between densely nitrogen-doped graphene layers (DNG/MoS2) to achieve high volumetric capacity, high rate performance, and long-term stability for sodium storage. The DNG/MoS2 material exhibits high gravimetric and volumetric capacities, remarkable rate performance, and outstanding cycle stability. The assembled sodium ion capacitor based on DNG/MoS2 also demonstrates high energy densities and long-term cycle stability. This work provides new insights for designing high density advanced electrode materials.

Summary: In this study, a robust composite solid electrolyte interphase (C-SEI) consisting of fluorine doped boron nitride and organic polyvinyl alcohol is proposed. Experimental results show that the C-SEI modified lithium anode exhibits dendrite-free performance, stable cycling, and ultra-low overpotential. The capacity retention rate is also significantly improved by using the C-SEI. These findings provide a feasible strategy to address the instability of solid electrolyte interphase and demonstrate great prospects for the practical application of lithium metal batteries.
