HIGH-VOLTAGE, ROOM TEMPERATURE SINGLE-ION POLYMER ELECTROLYTE FOR SAFER ALL-SOLID-STATE LITHIUM METAL BATTERIES
Horizon Europe | Grant agreement ID: 101069703
July 2022 – June 2026
The greatest challenges towards the worldwide success of battery-powered electric vehicles revolve around the safety, energy density, and cost of the battery technologies. Solid-state polymer electrolytes and lithium metal anode address these challenges by replacing the flammable and unstable liquid electrolytes and enabling dendrite-free cycling of high-energy lithium metal cells manufactured by sustainable and cost-effective processing.
The PSIONIC project advances the development of all-solid-state battery technology by employing amorphous cross-linked Polyethylene oxide (PEO) laminated on the thin lithium foil at the anode and high voltage cathode coated with a single-ion conductive polymer. This will allow to replace the flammable and unstable liquid electrolytes and enabling dendrite-free cycling of high-energy lithium metal cells manufactured by sustainable processing. Special attention will be devoted to the optimization of interfaces between the active material and polymer electrolyte. Materials selection will enable the use of the manufacturing technology available at BlueSolutions, which is readily scalable, based on sustainable processing using solvent-free extrusion.
PSIONIC is aiming to develop cells with a safety hazard level 2, since no liquid component will be in the cell at the end of the project. The research and innovation actions carried under the PSIONIC project will not only just contribute to the technological advancements of all-solid-state Li-ion batteries in terms of safety, reliability, performance, cost, and sustainability, but will also enable higher uptake by the electromobility sector and end consumers, paving a pathway towards climate neutrality, and green energy transition
Within this project, SPECIFIC POLYMERS brings its expertise in the development advanced and chemically controlled thermosetting polymers and single-ion conductors. Several generations and strategies are confronted to validate best candidates to upscale. Particular attention is paid to their electrochemical stability, conductivity, compatibility with electrodes and extrudability.
To produce module prototype, SPECIFIC POLYMERS is also responsible for optimizing and transferring of the production of the electrolyte materials to pilot lab. As part of its knowledge, SPECIFIC POLYMERS is thus taking care of using raw materials and synthesis conditions (synthesis pathways, equipment, purification methods, …) compatible with industrial processes.
