The supercritical carbon dioxide (scCO2) is a greener approach. It is a method that can liberate polymeric binder from active material while protecting the structure of the binder. This is not only paving the way to reuse the binder for new battery production but also prevents toxic fluorine gas release to environment. It is also quite useful method that liberate the active material from the current collector which ease the next recycling process for active material. In this study, scCO2 and co-solvent system was investigated for the efficient recovery of PVDF binder from spent LIBs.
