CIRCUBAT: A CIRCULAR ECONOMY FOR LITHIUM-ION BATTERIES

CircuBAT develops a sustainable framework for lithium-ion batteries from design to recycling, with Switzerland Innovation Park Biel/Bienne leading module disassembly research.

Switzerland Innovation Park Biel/Bienne connects academic research and industry within CircuBAT, enabling scalable solutions for battery disassembly and circular reuse.

CircuBAT, launched in 2022 under Innosuisse’s Flagship Initiative, is one of Switzerland’s most ambitious battery sustainability projects. Led by Bern University of Applied Sciences (BFH), the project unites seven research institutions and 24 industrial partners to advance a circular economy for lithium-ion batteries across their entire lifecycle.

The initiative tackles every phase of battery use: from extending the first-life performance of electric vehicle batteries, to designing second-life applications for stationary energy storage, and ultimately ensuring efficient recycling and resource recovery. Subprojects include the development of dry electrode production techniques to lower manufacturing emissions, intelligent battery management systems to prolong usability, and eco-efficient recycling methods using water-based separation technologies.

The Switzerland Innovation Park Biel/Bienne was selected due to its expertise in applied research and development, particularly in the area of battery technology and  is centrally involved in Subproject, where researchers are creating standardized procedures and technologies for disassembling battery modules. These innovations support safe, cost-effective retrieval of valuable components and enable scalable recycling. The work done at the Park bridges the gap between academic research and industrial deployment.

CircuBAT’s integrated approach has national significance: it supports Switzerland’s energy transition strategy while reducing reliance on imported raw materials. The research outcomes will inform new business models, guide policymaking, and set technical benchmarks for battery reuse and recycling within a European context.
