| Abstract | The giant wheel-shaped Na15{[Mo154O462H14(H2O)70]0.5[Mo152O457H14(H2O)68]0.5}·ca. 400 H2O (Mo154) is one of the fascinating clusters with the open host framework, which is designed by simple metal-oxygen fragment–linked coordination modes. The generation of structural vacancies (here referred to as defects), the substitution of ligands, and incorporation of heterometallic centers in Mo154 could offer several attractive possibilities to achieve good electrochemical performance such as high specific capacity and stability in multivalent batteries. Herein, we have introduced electronically rich giant nanowheel Mo154 as a potential cathode material in magnesium-rechargeable batteries (MRBs). The experimental evidence indicates that the Mo154 wheels offer a reversible capacity of ∼150 mAh g−1 at 50 mA g−1 in MRBs, which was retained to about 55 mAh g−1 after a long cycling life (>500 cycles). Typically, the divalent alkali metals (Mg2+) suffer from diffusion and insertion reactions in host materials; however, the stable and high rate performance against cycling with good Coulombic efficiency was achieved for Mo154 electrodes. Thus, the work demonstrates that the complex inorganic clusters are promising cathode materials in multivalent ion batteries. |
