DIRECT RECYCLING METHOD FOR LITHIUM-ION BATTERIES

A method is provided for producing a cathode active material. The method includes providing an anode sheet comprising an anode material disposed on an anode current collector and a cathode sheet comprising a cathode material disposed on a cathode current collector, delaminating the anode material from the anode current collector, separating the anode material from the anode current collector, and delaminating 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.
