In the fourth episode of the BatWoMan podcast, Theresa speaks with Iratxe de Meatza, who leads the work package on solvent-reduced electrode processing within the BatWoMan project. Their discussion focuses on the practicalities and complexities of advancing lithium-ion battery manufacturing towards more sustainable practices.
Iratxe provides a detailed overview of the project’s approach to reducing the use of solvents in electrode production. Key topics include:
- Dry Processing Challenges: The technical hurdles in achieving proper mixing and flow of solid materials without the aid of traditional liquid solvents, and the trade-offs involved in terms of energy consumption.
- Steps Toward Safer Alternatives: Efforts to replace volatile organic compounds (VOCs) with water-based solutions as an interim step, reducing toxicity and environmental impact while maintaining process efficiency.
- Long-Term Goals: The vision of completely solvent-free manufacturing processes and the incremental steps required to reach this ambitious target.
The conversation also touches on the broader implications of these developments, such as the potential for reducing environmental footprints in battery production and improving worker safety. Iratxe’s insights provide a grounded perspective on the real-world challenges and opportunities in transitioning to more sustainable manufacturing methods.
