This project aims to achieve high-energy lithium-oxygen batteries for electric vehicles. Electrification of road transport will minimise consumption of fossil fuels, reduce carbon dioxide emissions, and increase energy security. Lithium-oxygen batteries have the highest energy density among all rechargeable battery systems, which is more than 10 times the density of current lithium-ion batteries. Through exploration of new catalysts, redox mediators, and porous material architectures, this project intends to significantly improve the performance of lithium-oxygen batteries, including specific capacity, cycle life and round-trip efficiency.

该项目旨在实现电动汽车用高能锂氧电池。道路运输的电气化将最大限度地减少化石燃料的消耗，减少二氧化碳排放，并加强能源安全。在所有充电电池系统中，锂氧电池的能量密度最高，是目前锂离子电池密度的10倍以上。通过探索新的催化剂、氧化还原介质和多孔材料结构，该项目旨在显著提高锂氧电池的性能，包括比容量、循环寿命和往返效率。
