Researchers from Cambridge University, together with a team from Beijing Institute of Technology, developed a unique multifunctional sulphur electrode that combines an energy storage unit and an electron/ion transfer system.
The electrode uses a metal organic framework (MOF) as a 'template' to produce a conductive porous carbon cage. Sulphur within the cage acts as the host and each sulphur-carbon nanoparticle acts as an energy storage unit. Graphene is wrapped around the sulphur electrode to speed the transfer of ions and electrons.
The electrode is regarded as holding great promise, providing a way of both enhancing the use of sulphur and improving the cycle stability of batteries.
