Lithium-ion battery recycling Escaid™ diluents for solvent extraction
From 2021 to 2030 lithium-ion batteries’ global production is expected to grow by 5x to 5,500 GWh, with EV batteries making up nearly 80% of all lithium-ion batteries produced1.
This rapid growth is creating opportunities and challenges for the complete supply chain, from raw material suppliers to EV battery manufacturers and recyclers. There are significant market pressures to increase production capacities, streamline logistics and optimize costs of critical raw materials such as Lithium, Cobalt, Nickel and Manganese in order to serve the developing global EV market.
ExxonMobil can support raw material suppliers, EV battery manufacturers and recyclers in their efforts to produce, recover and recycle Lithium, Cobalt, Nickel and Manganese via solvent extraction processes.
Solvent extraction (SX) battery recycling can enable +90% recovery of the rare metals at +95% purity with cost-effective capital investments, high material selectivity, low energy consumption and without toxic fumes when compared to other recovery processes2,3.
