Summary: Room-temperature sodium-sulfur batteries have high energy density and low cost, but the presence of high-order polysulfides leads to capacity fading and low-order polysulfides have slow reaction kinetics. This study introduces microporous-mesoporous carbon derived from mangosteen peels as cathode materials, which effectively suppresses the shuttling effect of sodium polysulfides, and provides high electrical conductivity and porosity for efficient electron/ion diffusion. The obtained sodium-sulfur battery exhibits high reversible capacity, excellent long-term cycle performance, and outstanding rate performance.

Summary: In this work, 3D amorphous mixed-valence VOx microspheres were in situ grown on alkali-treated carbon cloth (VOx MSs@ACC) as cathodes for AZIBs. Compared to a VOx MSs powder-constructed cathode, VOx MSs@ACC cathodes exhibit higher specific capacity (1.79 mA h cm(-2) at 2.7 A m(-2)) and longer cycling performance over 2500 cycles mainly due to their faster ion transport rates, abundant ion storage sites, and more effective easing of volume expansion. This work sheds light on the design of free-standing vanadium-based cathodes for AZIBs.
