Abstract:
Novel nanocubic KTi2(PO4)3 was successfully fabricated via a facile hydrothermal method combined with a subsequent annealing treatment and further evaluated as an electrode material for potassium-ion batteries for the first time. For comparison, carbon-coated KTi2(PO4)3 obtained by a normal cane sugar-assisted method reveals improved electrochemical performances in potassium-ion batteries. This work may give a new insight into developing electrode materials for potassium-ion batteries.
