Design of new two-dimensional materials for lithium sulphur batteries. This project aims to develop classes of electrode material systems for high performance batteries. This project will design new hierarchical cathode composites for a high capacity lithium-sulphur battery with a long cycling life. It intends to improve energy density by confining active sulphur in conductive graphene and exfoliated titanium dioxide nanosheets, and use a unique hybrid protecting layer to suppress cycling instability. This research is expected to establish the relationship between synthetic conditions, structure, and electrochemical performance.

新型二维锂硫电池材料的设计。该项目旨在开发高性能电池的电极材料系统。该项目将为具有长循环寿命的高容量锂硫电池设计新的分层阴极复合材料。它打算通过将活性硫限制在导电石墨烯和剥离的二氧化钛纳米片中来提高能量密度，并使用独特的混合保护层来抑制循环不稳定性。这项研究有望建立合成条件、结构和电化学性能之间的关系。
