Abstract
The global market for lithium-ion batteries (LIBs) is experiencing substantial growth, with demand projected to rise further due to efforts to decarbonize transportation and energy sectors. Demand for LIBs is anticipated to grow from 700 GWh in 2022 to 4700 GWh by 2030. This steep growth has led to the establishment of numerous new Gigafactories worldwide. As battery production expands, the volume of scrap material generated will significantly rise. Due to high-quality standards in battery manufacturing, a notable portion of production will not meet these criteria, creating a growing stream of valuable resources surpassing end-of-life batteries. Conventional battery recycling relies on pyrometallurgical and hydrometallurgical processes, which are efficient in material recovery but are energy intensive and present environmental and economic burdens.
Direct recycling, a novel approach, has recently been proposed to recover active material while conserving its original structure
