Abstract

ABSTRACT Manganese (Mn)‐based cathode materials show great promise for aqueous zinc‐ion batteries (AZIBs) owing to their inherent safety and low cost. However, they still suffer from substantial disadvantages, such as Mn dissolution and structural degradation. To address these issues, we designed a multiphase Mn‐V oxide/carbon composite (MnVO/C‐2) derived from a bimetallic Mn‐V‐based metal–organic framework (MOF). The incorporation of vanadium results in a well‐defined heterostructure consisting of MnO, MnV 2 O 4 , and V 2 O 3 phases. This multi‐component architecture not only provides abundant active sites for redox reactions but also effectively mitigates volume variation via strain compensation at phase…
