A low-strain phosphate cathode material K₃(VO)(HV₂O₃)(PO₄)₂(HPO₄) (KVP) nanoruler is synthesized by a facile solvothermal approach. The KVP nanorulers manifest high discharge voltage, superior rate capability, and ultralong cyclic life as a cathode material for potassium-ion batteries (PIBs). This work would provide guidance to exploit high-performance PIB cathode materials.
