Novel K₂Ti₈O₁₇ is successfully fabricated via a facile hydrothermal method combined with a subsequent annealing treatment and further evaluated as an anode material for potassium-ion batteries for the first time.

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.

Metal–organic frameworks (MOFs) have recently attracted much interest in electrochemical fields due to their controlled porosity, large internal surface area, and countless structural topologies.
