Innovative materials
Graphene batteries AS developed high surface area porous carbon material with 3D inter connected network. This structure 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.
