Key Points

The new SrZr₀.₈Y₀.₂O₃ perovskite achieves an impressive 1164.9 F g⁻¹ at 2 A, demonstrating high performance.
Traditional oxygen-ion perovskites struggle with slow ion transport and instability, which this research addresses.
A mixed ion conductor using H⁺ and OH⁻ allows for improved function compared to conventional materials in pseudocapacitors.
Enhancing ion transport in electrodes like these could lead to more efficient energy storage devices.
