Jahn–Teller Distortion Induced Mn2+‐Rich Cathode Enables Optimal Flexible Aqueous High‐Voltage Zn‐Mn Batteries

Jahn–Teller Distortion Induced Mn2+‐Rich Cathode Enables Optimal Flexible Aqueous High‐Voltage Zn‐Mn Batteries

Abstract Although one of the most promising aqueous batteries, all Zn‐Mn systems suffer from Zn dendrites and the low‐capacity Mn4+/Mn3+ process (readily leading to the occurrence of Jahn–Teller distortion, which in turn causes structural collapse and voltage/capacity fading). Here, the Mn3+ reconst...
