Outline of Research at the Start

Renewable energies are promising clean power suppliers, whose intrinsic intermittency should be balanced by efficient electrochemical energy storage devices such as Li-ion batteries; however, the limited Li resource, safety risks and cost of Li-ion batteries become new issues. Hence, exploring new battery systems is urgent required. Aqueous proton batteries stands out in various candidates due to its potential to deliver large capacities with fast rates and long-life led by the small size of proton. Herein, we aim to design proton batteries by decoding the proton intercalation mechanisms.

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.
