High-Performance Mn-Based Hybrid Aqueous Batteries Enabled by Interlayer-Expanded Magnesium Vanadium Bronze Cathode.

ABSTRACT: Manganese-based ion batteries exhibit a relatively low redox potential (-1.19 V vs SHE) along with high theoretical capacity and excellent capacity retention characteristics, making them promising for next-generation batteries. In this study, a high-performance manganese hybrid aqueous battery with an expanded interlayer spacing is designed and fabricated using MgV₆O₁₆·7H₂O (MgVO) as the cathode material and manganese metal as the anode. The fabricated Mn metal battery achieves an initial discharge capacity of 195.3 mAh g^-1 (with Mn metal anode) at a current density of 0.1 A g^-1 with 1.19 V and exhibits excellent capacity retention of even after 200 cycles at a current density of 0.4 A g^-1. Furthermore, detailed structural b
