💡 Novelty & Significance:
This study reveals that multiscale stereochemistry—atomic-scale distortion and nanoscale short-range ordering—governs potential hysteresis in Li||DRX cells. Redox-inactive d0 transition metals, via the pseudo Jahn–Teller effect, weaken Ni–O charge transfer and enhance lattice oxygen redox reversibility. This insight enables rational design of DRX electrodes with reduced hysteresis and improved energy efficiency.
