A Single‐Phase, All‐Solid‐State Sodium Battery Using Na₃₋<i>_x</i>V₂₋<i>_x</i>Zr<i>_x</i>(PO₄)₃ as the Cathode, Anode, and Electrolyte

Abstract

“Single-phase” all-solid-state battery, based on Na3−xV2−xZrx(PO4)3 as the cathode, anode, and electrolyte, is reported. It successfully undergoes room temperature charge–discharge reactions based on the V3+/V2+ (anode) and V3+/V4+ (cathode) redox systems with insertion reaction. The interfacial resistance is essentially zero at the anode and cathode. As a service to our authors and readers, this journal provides supporting information supplied by the authors.
