| Outline of Annual Research Achievements |
Sufficient and sustainable electric energy supply is indispensable for modern society. Therefore, developing functional materials for high-rate, safe and low-cost aqueous battery systems becomes an urgent task. In last year, we have successfully decoded the proton intercalation mechanisms in two representative compounds: MoO3 and VOPO4, and explored their performances as electrode materials for aqueous proton batteries. MoO3 exhibited an ultrahigh rate capability that can realize a fast charge/discharge within 8 seconds, which can be explained by anhydrous Grotthuss mechanism. VOPO4 showed a relatively high potential due to its polyanion structure. Except for the application as battery material, we also verified the function of MoO3 as a redox mediator for decoupled water splitting system.
