HYLESS

DEMONSTRATION OF A HIGH-CAPACITY ANODE-LESS SOLID STATE LITHIUM BATTERY

Prototype of a secondary solid-state battery without a metallic anode, aligned with the paradigm of the “fourth generation” of sustainable energy storage systems. The proposed configuration includes the use of a lithium-rich positive electrode with low cobalt (Li₁.₂Co₀.₁₃Ni₀.₁₃Mn₀.₅₄O₂), a negative electrode based on a microstructured stainless steel film via laser and coated with a hybrid film based on PEO and LiNO₃, and a polymeric solid electrolyte cross-linked, enriched with non-flammable ionic liquids to ensure stable high-voltage cycles. The project includes the experimental production of the complete system in coin cell configuration and its validation under representative application conditions, achieving a TRL3.

The work entails the formulation and characterization of both positive and negative electrodes with liquid electrolyte, the production and validation of the solid electrolyte in partial cells, the optimization of the complete system and the measurement of the electrochemical performance of the PoC in a real configuration. The entire development will be supported by a multi-level communication and dissemination strategy, structured to maximize the project's impact on academic and industrial stakeholders as well as the general public.
