Summary

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 and long 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 negligible overpotentials, high rates and stable electrochemical performance. In this talk, I will introduce some exciting rechargeable hydrogen gas battery chemistries, including novel nickel-hydrogen gas, manganese-hydrogen gas, proton-hydrogen gas, and among others. The novel nickel-hydrogen gas battery technology has been recently transferred successfully to the industry. In addition, manganese-based batteries with Mn2+/MnO2 redox reactions as the cathode, and Zn-based batteries will be discussed.
