V-Induced Low-Spin State Mn3+ Suppresses Jahn-Teller Distortion for High-Performance Aqueous Zinc Ion Batteries
{{output}}
The Jahn-Teller distortion caused by high-spin state Mn3+ (t2g 3eg 1) is a major limiting factor for improving both the specific capacity and cycling stability of MnO2 cathodes in aqueous zinc-ion batteries. Thus, an intrinsic strategy for optimizing MnO2 invo... ...
