K3V2(PO4)3 (KVP) is a highly promising, low-cost cathode material for Potassium-Ion Batteries (PIBs). It belongs to polyanion family of electrode materials and is distinguished by its stable, three-dimensional NASICON structure. The reaction is sustained by the V3+/V4+ redox couple. The primary reaction typically occurs at a remarkably flat and high voltage plateau of ~3.4 V vs. (K/K+) and its theoretical specific capacity can be up to 106 mAh/g.
