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.
