What is ReLiB?
ReLiB is a £18m basic research project led by University of Birmingham, that aims to provide technological solutions, and thought leadership, to the challenges of re-using and comprehensively recycling lithium-ion batteries of different chemistry systems. Our UK academic collaborators are The University of Edinburgh, Newcastle University, University of Leicester, University of Oxford, Imperial College London & University College London.
Our Aims
The aim of the ReLiB project is to establish the Technological, Economic and Legal infrastructure required to optimise the efficiency of material management from Lithium-ion batteries utilised in the automotive sector. By implementing circularity practices, we aim to promote long-term sustainability by conserving the valuable resources and minimizing the environmental impact.
What is ReLiB's Vision?
Vision
Our goal is to provide a UK EV battery recycling industry with a pipeline of scalable ReLiB’s latest technologies that are responsive to regulatory drivers, new battery designs and chemistries, and the opportunities afforded by Industry 4.0.
5 Year View
In five year’s time we aim to see the following technologies developed – and scaled:
- Cathode leaching work to industrial level.
- Upcycled electrode materials used in new cells.
- Binder recovery (where there is an economic or regulatory rationale to do so).
- Biorecovery of materials e.g. metals from plastic EV battery waste, from secondary waste solutions—’zero waste’ concept—(where there is an economic or regulatory rationale to do so).
- Smart disassembly, separation and regeneration technologies e.g. direct recycling to protect the material crystal structure and embedded value of electrode material for reuse.
- Digital diagnostic tools that can interface seamlessly with battery data passports to assess the state of health of batteries and inform recycling routes.
- Identification of new research topics that fit with changing battery design & chemistry systems and regulatory drivers.
