Zusammenfassung:	Embodiments described herein relate to recycling of electrochemical cell materials. In some aspects, a method can include separating a stack pouch material from an electrochemical cell stack, separating a plurality of unit cells from the electrochemical cell stack into individual unit cells, cutting within a heat seal of a cell pouch of a unit cell from the plurality of unit cells, separating a cathode material and a cathode current collector away from a separator, an anode material, and an anode current collector of the unit cell, placing the cathode material and the cathode current collector in a solvent bath with the cathode current collector facing downward, separating the cathode material from the cathode current collector via an ultrasonic probe, separating solids and liquids of the cathode material, drying the solids of the cathode material, and incorporating the solids of the cathode material into a new cathode mixture.
