|报告题目：Design and Synthesis of Nanostructured Catalysts for Improved Zinc-Air Battery Performance
High energy density, low cost, and good safety make zinc-air batteries (ZnABs) highly attractive for a wide range of applications from personal electronics to large scale power grids. Although primary ZnABs have found commercial success in some niche areas, the rechargeable ZnABs are still in the early stages of development where solutions to various technical challenges are needed. Particularly the catalytic air cathode, the unsatisfactory catalytic activities toward oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) limited the battery charge-discharge efficiency and cycle life.
In this presentation, I will report several efficient catalysts1,2 and discuss how their nanostructures benefit the catalytic activities toward ORR and OER. To enable high-performance ZnABs, I will also demonstrate an efficient and robust air-cathode3 constructed by direct growth of catalytic nanomaterials onto a nickel foam.
