摘要	The cathode active materials in lithium-ion batteries (LIBs) possess significant recycling value. However, separating these materials from the binder and the cathode current collector (Al foil) is challenging. This study proposes a method for separating cathode active materials by vaporizing the current collector by underwater pulsed discharge. Discharge experiments were conducted with voltages spanning from 3 to 6 kV and using the cathode sheet as the load. The simulation indicated that the temperatures of the current collector and the binder surpassed their vaporization and pyrolysis temperatures respectively. The separate effects of the experimental products are as follows: the current collector was almost completely removed in big-particle products (particle size > 74 μm), and partially separated in medium-particle products (25 μm © 1973-2012 IEEE.
