V‐Induced Low‐Spin State Mn 3+ Suppresses Jahn–Teller Distortion for High‐Performance Aqueous Zinc Ion Batteries

, thereby suppressing the Jahn-Teller distortion and enhancing cycling stability. This study offers profound insights into the inhibition of the Jahn-Teller distortion from an electron spin perspective, and presents a facile approach to synergistically enhance specific capacity and cycling stability.
