Abstract
En 中文
A novel V2O3@C/S composite cathode material is prepared via a combined strategy consisting of solution synthesis, hydrothermal treatment and high-temperature carbonization, and all solid-state lithium‑sulfur (LiS) batteries with high-performance are constructed. The obtained V2O3@C host material demonstrates excellent properties, including good structural stability, superior electrical conductivity, strong interfacial compatibility, notable sulfur adsorption and high catalytic capabilities. At a current rate of 0.1C, the V2O3@C/S cathode delivers an initial capacity of 1125 mAh g−1 with a capacity retention of 67.1 % after 150 cycles in solid-state cells at the room temperature. At 0.5C, the capacity retention still remains 45.5 % after 250 cycles. Cyclic voltammetry, electrochemical impedance spectroscopy, and Tafel analysis further demonstrate the enhanced reaction kinetics and reduced charge-transfer resistance. This work provides a promising strategy for designing the high-performance cathode materials of solid-state LiS batteries.
