High-performance pseudocapacitors enabled by H<sup>+</sup>/OH<sup>−</sup> mixed ion conductors in perovskite electrodes

Oxygen-ion intercalation perovskites in pseudocapacitors suffer from slow ion transport and instability. Here, we propose a SrZr<sub>0.8</sub>Y<sub>0.2</sub>O<sub>3</sub>-based perovskite, a H<sup>+</sup>/OH<sup>-</sup> mixed ion conductor, achieving 1164.9 F g<sup>-1</sup> at 2 A g<sup>-1</sup>. The Mo doping strategy enhances the capacitance to 1467.7 F g<sup>-1</sup> at 2 A g<sup>-1</sup>, demonstrating superior performance and stability for advanced supercapacitors.
