Stabilising Conversion Anodes with Solid Molecular Ionic Composite Electolytes for Solid State Lithium Ion Batteries - SMICE-Li

Project summary

Solid State Batteries (SSBs) represent the most promising "next-gen" chemistry for Li-based batteries, as they combine the substantially increased energy density (>450Wh/kg) and improved safety that is needed to accelerate a societal shift from fossil fuels. Their development is currently stalled however, by challenges related to electrolyte performance at lower temperatures, and by problems controlling the efficient deposition and stripping of metallic lithium anodes. The SMICE-Li project proposes a new and entirely novel approach to address these problems, by combining high capacity conversion-type anode materials (CAMs) with a new class of solid state Li-ion electrolyte: A Solid Molecular Ionic Composite Electrolyte (SMICE). SMICE-Li will combine predictive modelling with fundamental interphase studies to tailor and match materials for best performance, with the objective of demonstrating the potential of an entirely new class of SSB that addresses the problems limiting current SSBs
