SOLiD: building a sustainable future for high-performance solid-state lithium-metal batteries

Key Points

Pilot-scale manufacturing creates safer, recyclable solid-state lithium-metal batteries.
Using roll-to-roll methods, the project minimizes critical raw materials like cobalt and lithium.
The project demonstrates a cost-efficient process for high-energy density batteries.
Focus on sustainable practices may support the future of battery manufacturing.

Abstract

SOLiD: building a sustainable future for high-performance solid-state lithium-metal batteries SOLiD is an EU-funded project whose main objective is to create a sustainable, cost-efficient pilot-scale manufacturing process for a high-energy density, safe and easily recyclable solid-state Li-metal battery. The roll-to-roll (R2R) dry ex-trusion coating and cost-efficient R2R PLD methods enable the sustainable manufacturing of Gen. 4b solid-state bat-teries with a minimised amount of critical raw materials (Co and Li).
