Abstract
A method is provided for producing a cathode active material. The method includes shredding an anode sheet including an anode material disposed on an anode current collector with a cathode sheet including a cathode material disposed on a cathode current collector, rinsing the sheets with an organic solvent, agitating the sheets to delaminate the anode material from the anode current collector, separating the anode material from the anode current collector using a filter and/or a sieve, and blending the anode current collector and the cathode sheet to delaminate the cathode material from the cathode current collector. The method further includes performing size reduction and deagglomeration on the cathode material, which includes the cathode active material and a binder, separating the cathode material from the cathode current collector using a filter and/or a sieve, and performing gravity separation to separate the cathode active material from the binder.
