If you are an e-mobility brand dealing with high battery costs and environmental footprints — this project developed a dry electrode process that reduces energy use by 27%. This allows for customized 21700 cells tailored to your specific vehicle needs.
Eco-friendly Industrial Production of Custom 21700 Lithium-Ion Battery Cells
Imagine making battery parts like baking a cake without needing to add water or oil first, then spending hours drying it in a giant oven. This project replaces the messy, chemical-heavy liquid process with a dry method that's faster and cleaner. It's like switching from wet paint to a dry-transfer system to get the job done with less energy and waste.
What needed solving
Current battery production relies on hazardous solvents and energy-intensive drying processes dominated by non-European manufacturers. This leads to high operational costs and a heavy environmental footprint.
What was built
An industrial-scale production line for 21700 cylindrical lithium-ion cells using a solvent-free dry electrode process.
Who needs this
Who can put this to work
If you are a tool manufacturer dealing with the need for high-performance, durable power cells — this project developed a solvent-free manufacturing line. It provides high-quality, customizable cells while cutting carbon emissions per cell by up to 5%.
If you are an electric aircraft developer dealing with strict weight and performance requirements — this project developed a flexible production platform for premium cells. It enables a fully European value chain to reduce reliance on external markets.
Quick answers
How does this impact production costs?
The dry process reduces costs by removing the need for expensive drying equipment, air treatment systems, and solvent recovery infrastructure. It also lowers energy consumption by approximately 27%.
Is this technology ready for industrial scale?
Yes, the main objective is to establish the first industrial-scale production line in Europe for cylindrical 21700 lithium-ion battery cells using the dry electrode process.
What is the IP or licensing status?
Based on available project data, the technology is being developed by Univercell Holding GmbH to create a European manufacturing platform, though specific licensing terms are not listed.
What are the environmental benefits?
The process eliminates hazardous chemicals like N-Methyl-2-pyrrolidone and is projected to drop carbon emissions per cell by up to 5%.
What is the timeline for implementation?
The project period runs from 2024-07-01 to 2026-06-30.
Who built it
The project is led by a single German SME, Univercell Holding GmbH, which is taking 100% of the industrial responsibility. This lean structure suggests a highly focused commercialization path, supported by a total financial package including a EUR 2,387,000 grant and a requested EUR 15 million EIC investment.
