Abstract

Novel K₃V₂(PO₄)₃ and three-dimensional conductive network K₃V₂(PO₄)₃/C nanocomposites are successfully fabricated and further evaluated as cathode materials for potassium-ion batteries for the first time. The K₃V₂(PO₄)₃/C nanocomposite exhibits a high-potential platform of 3.6-3.9 V and a good capacity retention of at least 100 cycles. This work may provide new insight into developing cathode materials for potassium-ion batteries.
