Project
Solid-state batteries (SSB) present a promising opportunity for the EU to strengthen its position in the global battery market. SOLVE will tackle key barriers to growth by demonstrating innovations across the value chain, optimizing and upscaling materials, cell components, SSB cells and processing techniques under industrial conditions (TRL ≥ 6).
Value chain
1
Electrolyte: SOLVE will optimize the formulation and large-scale processing of thin hybrid solid polymer-based electrolytes (HSPE) that are defect-free highly ionic conductive, electrochemically stable and intrinsically safe.
Cathode: SOLVE will develop and optimize the integration and processing of high loading composite cathodes (up to 4 mAh/cm2) based on upscaled surface engineered Ni-rich and Li-rich NMC materials and advanced catholyte.
Anode: SOLVE will develop and optimize two types of anodes, for both Li-metal and anode-free SSB.
2
Towards Gigafactory scale! SOLVE will demonstrate the manufacturing feasibility of 10-20 Ah SSB pouch cells at relevant scale ensuring compatibility between components and materials, optimising its design with respect to individual components and relevant testing protocols.
Digitalisation: SOLVE will ease the design of Gen4b SSBs by leveraging innovative material-specific models and digital tools.
3
Green Transportation: SOLVE will integrate 10 Ah SSB in 0.25 kWh module to maximize the adoption and industrial exploitation of its results during and after the project, benefiting both aviation and automotive mobility.
4
SOLVE will ensure the sustainability and resource efficiency of SSB by demonstrating innovative recycling concepts. It will showcase highly sustainable, circular manufacturing of advanced materials at Gigafactory scale, in accordance with the EU Battery Regulation.
