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.

锂-空气（Li-air）电池具有最高的能量密度，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、能效差和循环寿命有限等挑战的阻碍。该项目旨在通过分子调节设计具有多层结构的功能性准固体凝胶聚合物电解质，开发具有长循环寿命的高能锂空气电池原型，这可能为下一代电动汽车提供动力。该项目预计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，从而使经济和环境受益。
