This project aims to develop new membranes for use as separators in lithium-sulphur batteries. Currently diffusion of polysulphides within these batteries reduces battery power and lifetime. The new membranes are intended to block polysulphide diffusion over an extended lifetime, while transporting the other ions needed for the battery to function. The project is expected to generate new membrane materials and further knowledge about the design, synthesis and larger-scale production of membranes for electrochemical applications. This project will provide significant benefits by producing potentially lighter, longer-lasting and cheaper batteries than existing lithium-ion technologies, with the potential to accelerate the adoption of electric cars.

该项目旨在开发用作锂硫电池隔膜的新膜。目前，多硫化物在这些电池内的扩散降低了电池功率和寿命。新的隔膜旨在延长寿命，阻止多硫化物扩散，同时运输电池工作所需的其他离子。该项目预计将产生新的膜材料，并进一步了解电化学应用膜的设计，合成和大规模生产。该项目将通过生产比现有锂离子技术更轻，更持久和更便宜的电池来提供显着的好处，并有可能加速电动汽车的采用。
