K<sup>+</sup> doping-induced pillaring effect in Na<sub>3</sub>V<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> for enhanced rate performance in sodium-ion batteries
K ions act as "molecular pillars" in NVP, propelling lattice expansion to create unobstructed Na<sup>+</sup> migration channels and stabilize the structure against collapse during cycling. This pillaring effect also accelerates charge transfer kinetics and facilitates rapidly reversible phase transition <i>via</i> intermediate phase formation, enhancing overall battery performance.
