Due to the steadily increasing production of lithium-ion batteries and their widespread use in the field of e-mobility, a high volume of spent batteries with a variety of valuable materials (e.g. lithium, nickel, cobalt, copper and manganese) can be expected in the near future. Efficient and robust recycling of end-of-life lithium-ion batteries offers the possibility of returning valuable components to the material cycle and immensely reducing the carbon footprint of the batteries.
Within the project InnoRec, a total of three routes for recycling lithium-ion batteries are being experimentally investigated and compared with each other, regarding ecological, economic and technical aspects. By combining mechanical, hydrometallurgical and pyrometallurgical process steps, recycling rates are to be optimised and potential for improvement is to be revealed. Furthermore, the chemical characterisation of the recyclates and the re-synthesis of the recovered materials into new battery cells are an essential part of the investigations. As a holistic project, InnoRec forms the bridge between the ProZell and greenBatt research clusters.
