In 2019, it was estimated that only about 5 % of lithium-ion batteries were recycled. The market for lithium-ion batteries is expected to grow tenfold the coming decade, mostly driven by the growth in the number of electrical vehicles. The low recycling rate and the high growth demonstrates the need for increased focus on recycling and improved recycling technologies. A team of scientists from SINTEF will the coming year be working on innovative solutions for recycling of batteries. Their new ideas spring from their wide experience in recycling of metals and molten salt electrochemistry. SINTEF is financing the project so that new inventions can be patented by SINTEF. Anne Kvithyll, Research Domain leader in SFI Metal Production, is the contact person to this project.
