Abstract

A method is provided for separating a binder from cathode active material particles. The method includes combining the binder, the cathode active material particles, water and solvent in a vessel to form a single phase. The method further includes allowing the single phase to settle and form a first phase and a second phase, and separating the first phase from the second phase. The first phase contains the solvent and the binder, and the second phase contains the water and the cathode active material particles.
