ORNL Uncovers Greener Method To Recycle Lithium-Ion Batteries

On June 1, 2021, the Oak Ridge National Laboratory (ORNL) announced that its scientists have developed a novel solvent that results in a more efficient process to recover valuable materials from used lithium-ion batteries. According to ORNL’s press release, this new method supports a stable domestic supply chain for new batteries and keeps old ones out of landfills.

Currently, the recycling process of batteries involves smelting, which is an expensive, energy-intensive process that releases toxic gas. This new process developed by ORNL, however, recovers cathode materials and aluminum foils from lithium-ion batteries using a less hazardous solvent. It is a wet chemical process that uses triethyl phosphate to dissolve the binder material that adheres cathodes to metal foil. This process results in efficient recovery of cobalt-based cathodes and graphite, among other valuable materials, such as copper foils, that can be reused in new batteries. ORNL’s Ilias Belharouak stated that, in addition to repurposing materials, the new process reduces toxic exposure for workers. The full publication of ORNL’s study is available here.
