GREEN2MOVE

Prototyping potassium batteries

GREEN2MOVE aims to develop sustainable and scalable manufacturing processes for potassium-based batteries, placing Italy at the forefront of post-lithium energy storage research. By focusing on electrodes and other components production, the project introduces greener, safer, and more efficient technologies. It promotes water-based and solvent-free processing to eliminate toxic solvents like NMP, reduce energy use, and enable battery designs optimized for disassembly and recycling. Novel materials such as lignin-based binders and ionic liquid electrolytes are developed using a Design to Manufacture (DtM) approach tailored for industry 4.0 gigafactories. The project integrates digital solutions through a digital twin of the manufacturing process, enabling real-time optimization and predictive control. A strong focus on sustainability—including life cycle and cost assessments, and direct recycling strategies—guides R&D activities. Over 48 months, GREEN2MOVE will deliver high-TRL prototypes and contribute to a circular, competitive potassium battery industry in Europe, enhancing clean energy storage and supporting economic growth.

Research objectives

Green manufacturing of potassium batteries
Develop innovative electrode and cell component processing techniques—such as water-based and dry (solvent-free) methods—to eliminate harmful solvents, reduce energy and resource consumption, and enable eco-designed, recyclable potassium-ion batteries suitable for large-scale production.
Design to manufacture (DtM) and digital twin integration
Create and apply a data-driven DtM approach that supports process optimization, cost-efficiency, and factory flexibility. A digital twin of the manufacturing line will simulate, monitor, and adjust production in real time, aligning with industry 4.0/5.0 principles.
Enabling circularity and sustainability
Ensure the environmental and economic sustainability of the new technologies through life cycle assessment (LCA), life cycle costing (LCC), and direct recycling strategies. The goal is to maximize material recovery, minimize waste, and prepare the ground for a circular potassium battery value chain in Europe.
