Traditional Li-ion batteries are encountering a technical hurdle in further increasing their energy density. Li-S batteries have been attracted increasing attention owing to the high theoretical capacity of element sulfur (S, 1672mAhg−1). Nevertheless, the insulation nature of the S element and polysulfide shuttle effect, resulting in low S utilization and poor cycling stability, are the main obstacles...
A novel method which is based on the hydrothermal reaction was employed to synthesize LiV 3 O 8 . First, the mixture solution of LiOH, V 2 O 5 , and NH 4 OH was subjected to the hydrothermal reaction. The hydrothermal treatment yielded a clear, homogeneous solution. The evaporation of this solution led to the formation of a precursor gel. The gel was then heated...
