Title: Rechargeable Hydrogen Gas Batteries

Abstract:

Large-scale energy storage is of significance to the integration of renewable energy into electric grid. Rechargeable batteries show increasing interests in the large-scale energy storage. However, the challenging requirements of low-cost materials with long cycle and calendar life restrict most battery chemistries for use in the grid storage. Recently we developed a new generation of rechargeable hydrogen gas batteries by exploiting catalytic hydrogen evolution/oxidation reactions as the anode, which offers low overpotentials, high rates and stable electrochemical performance. In this talk, I will introduce some exciting rechargeable hydrogen gas battery chemistries, including aqueous nickel-hydrogen gas, proton-hydrogen gas, halogen-hydrogen gas, and nonaqueous lithium-hydrogen gas batteries. I will also discuss some extended applications on the hydrogen gas batteries, including self-charging batteries, decoupled water splitting, and metal-meditated nitrogen reduction. The rechargeable hydrogen gas batteries demonstrate attractive characteristics for large-scale and high-energy storage applications.
