Design of New Two-dimensional Materials for Lithium Sulfur Batteries (2016–2019)
Effective energy storage system plays an important role in the installation of renewable energies and electric vehicles. This project aims to develop new types of hierarchical cathode composites for high capacity lithium-sulfur battery with long cycling life. The key concepts are to confine high amount of active sulfur in porous framework of conductive graphene and exfoliated TiO2 nanosheets to improve the energy density, and to use a unique hybrid protecting layer to suppress the cycling stability problem. The relationship between synthetic conditions, structure, and electrochemical performance will be established. The outcomes will lead to innovative technologies in low carbon emission transportation and efficient energy storage systems.
