Li-S Battery Technology

A high surface area porous carbon with inter connected network is utilised as support for both anode and cathode. This structure was developed by Graphene Batteries and has already shown extremely promising results when applied as both anode and cathode support. At the cathode it provides a strong and flexible host structure which can accommodate the volume expansion experienced by sulfur during cycling. At the anode it provides stabilisation of the lithium-electrolyte interface, which will allow reduction of the electrolyte/sulfur ratio from a typical "excess" value of 10 µL/mg to a more commercially relevant value of 3 µL/mg.
