High-energy lithium-air batteries, a breathable future for renewable energy

锂空气(Li-Air)电池的能量密度最高，是商用锂离子电池的十倍。然而，锂空气电池的发展一直受到容量低、能量效率低和循环寿命有限等挑战的阻碍。本项目旨在通过分子调谐设计具有多层结构的功能性准固态凝胶聚合物电解质，开发出具有长循环寿命的高能锂空气电池原型，从而为下一代电动汽车提供潜在的动力。预计该项目将促进高性能锂空气电池的商业化，并促进可靠的储能设备的开发，从而实现经济和环境的双重效益。

Lithium-air (Li-air) batteries have the highest energy density which is ten folds over commercial lithium-ion batteries. However, the development of Li-air batteries has been impeded by challenges including low capacity, poor energy efficiency and limited cycle life. This project aims to develop a high-energy Li-air battery prototype with long cycle life by designing functional quasi-solid gel polymer electrolytes with multi-layer structures via molecular tuning, which could potentially power next-generation electric vehicles. This project is expected to facilitate the commercialisation of high-performance Li-air batteries and promote the development of energy storage devices that are reliable, benefiting both the economy and environment.
