SiGNE

The EU-funded SiGNE project aims to develop advanced lithium-ion battery technology with higher energy density, optimised chemistry and faster charging time compared to state of the art. To achieve their goals, researchers will use a certain amount of silicon in the anode and electrically connect it to the graphite material. Nanowires will improve silicon’s beneficial properties by increasing the amount of available surface area in contact with the electrolyte. A sustainable fibre-based separator will be developed, acting as an isolation layer between the anode and cathode. Researchers will demonstrate the innovative battery at scale to enable its adoption in electric vehicles. Furthermore, they will consider circular economy principles to address second-life applications once the lifespan of the battery comes to an end.
