ELIBAMA - European Li-Ion Batteries Advanced Manufacturing (October 2014)

Motivation & Objectives

Electric Vehicles (EVs) represent the future of sustainable road transport. Yet the path towards mass-scale production of large lithium-ion batteries, as necessary for electric vehicles, is confronted with several challenges.

ELIBAMA project aims to enhance and accelerate the creation of a strong European automotive battery industry structured around industrial companies already committed to mass production of Li-ion cells and batteries for EVs. It will research advanced eco-design methods in order to guarantee great cost reductions and significantly enhance the environmental profile of the battery through its life-cycle.

Technical Approach

The project is structured in technical bricks addressing the different manufacturing steps:

 

  • Development of cost-effective and eco-friendly processes for the coating of electrodes
  • Development of electrolyte materials eco-friendly production as well as improved electrolyte filling processes
  • Improvement of battery cell design and assembly processes (stacking, joining, …)
  • Development of new technologies and processes to improve downstream quality and reduce the rate of defective products at the end of the manufacturing chain
  • Optimization of batteries refurbishment and recycling
  • New proposal for second life applications
  • Life-cycle-assessment (LCA) studies to minimize manufacturing environmental impacts

Key achievements

WP1-2-3: The development at lab scale of the different innovative electrodes and cells’ processes has been finalized: the evaluations performed show promising results.

 

Aqueous based anode (cycling results)

Cells Non Destructive Test (fast and reliable cells’ quality check)

WP4: Demonstration at pilot level of manufacturing processes developed in WP1, 2 and 3: the pilot equipment are all available; the final assessments are in progress.

Structured collectors foils (improved adhesion)

Dry blend pilot electrode coating machine (no solvent at all)

WP5: The recommendations issued from the integrated environmental assessment of the different technologies have been integrated; an Eco-design tool has been provided.

 

LCA 1st savings’ assessment

WP6: High efficiency batteries recycling process development: electrolyte recovery and recycling efficiency trials have been performed. Adequacy of the electrochemical performances of used batteries after ageing with 2d life markets: cells’ 2d life cycling in progress.

 

Design of a high efficient recycling process (Improved cost – Reduced environmental impact)

WP7-8: Mid-term meeting and technical and financial report in April 2013. The cost and environmental indicators are in line with the project’s initial targets. The final savings are currently being estimated.
