HyList

The Objective of the HyLiST project is to develop high-energy, fast-charging, durable, safe, sustainable, and low-cost SSBs using eco-friendly processes that are close to conventional processes and novel SSB architecture.

Utilizing an innovative process technology for manufacturing Li metal by PLD method and hybrid single ion conducting polymer solid electrolytes (HSIPE) compatible with cobalt-free spinel lithium nickel manganese oxide (LNMO) high voltage cathodes is expected to enable large-scale production in Europe to reach 75€/kWh in 2027-2030, with minimal adaptation of existing production infrastructure. HyLiST develops high-performing, safe and sustainable generation 4b high-voltage solid-state battery materials, and cell concepts to demonstrate their applicability for automotive and aeronautics use cases increasing the technology readiness level from 4 to 6. The ambition of HyLiST is to lay the groundwork for the commercialization of cobalt-free cathode based SSB (LNMO|HSIPE|Li) cells and the uptake of this battery technologies in automotive and aeronautic applications.

Role of CIDETEC in the project:

CIDETEC Energy Storage is the leader of WP4 and will develop and optimize hybrid single-ion conducting solid polymer electrolytes with high mechanical stability and ionic conductivity to enable its application in LNMO||Li metal cells with practically relevant areal capacities up to 4 mAh cm-2 and will upscale HSIPE membrane fabrication for practical pouch cells. The expertise of CIDETEC in larger scale cell production will be used to provide support to the project partners assembling practical mono- and multi-layer pouch cells. CIDETEC will contribute in further workpackages to the analysis of interfaces between the electrodes and the solid polymer electrolyte to understand and overcome failure mechanisms. Using CIDETEC’s modelling capabilities, multiphysics and multiscale model development for electrode as well as cell design/assembly optimization based on a digital twin will be performed as holistic approach for a thorough understanding and to advance high-energy solid-state Lithium metal batteries further towards practical application.
