Enhancing the Reversibility and Kinetics of Heterovalent Ion-Substituted Mn-Based Prussian Blue Analogue Cathodes via Intervalence Charge Transfer.

Mn (d) in manganese-based Prussian blue analogues (MnPBA) exhibits intrinsic orbital degeneracy upon sodiation/desodiation, resulting in severe Jahn-Teller distortion, which usually causes rapid capacity decay and sluggish kinetics. Unfortunately, traditional modification strategies are insufficient for electronic tuning of Mn to mitigate these issues. Herein, Intervalence Charge Transfer (IVCT) of manganese and iron to vanadium ions is unraveled in a series of novel V-substituted MnPBA to enhance electrochemical reaction reversibility and kinetics.
