| titleOfInvention | Active material recovery device and recovery method based on pulse discharge vaporization of cathode current collector in water |
| abstract | The invention belongs to the technical field of active material recovery of positive electrode current collectors of lithium ion batteries. The invention proposes an active material recovery method based on pulse discharge vaporization of positive electrode current collectors in water, builds a test platform for pulsed discharge vaporized positive electrode current collectors in water, and uses ABS insulating plates to fix positive electrodes and the negative electrode, and connect the positive electrode and the negative electrode with a coaxial cable, the coaxial cable is connected to the pulse high current generating device, and then clamp the positive current collector with the positive electrode and the negative electrode; put it in the water tank, cover the cover plate, and vaporize the positive electrode current collector. By installing the negative electrode and the positive electrode inside the water tank, and clamping the negative electrode and the positive electrode on both sides of the positive electrode current collector, the coaxial cable and the negative electrode and the positive electrode can conduct electricity at the same time, so that the large pulse current flows to the positive electrode current collector, and the positive electrode current collector is in the A large amount of ohmic heat is deposited in a very short period of time, vaporization occurs rapidly, and breakdown occurs to generate plasma, which can achieve complete separation of positive active materials, binders, and current collectors, and recover valuable elements in lithium-ion batteries. |
