[0022] Specifically, open the cup lid 3, pour the appropriate extraction solution into the cup body 1, then pour the waste lithium-ion battery recycling material to be identified into the cup body 1, and close the cup lid 3 again, keeping it sealed with the silicone ring 32. Next, press the power button on the control panel 4 to power the device with the battery module. Adjust the stirring time, heating temperature, and stirring frequency using the time control knob, temperature control knob, and stirring frequency knob, respectively. Press the power button again to send a signal to the control motherboard 9. The control motherboard 9 controls the drive motor 10 to rotate the stirring rod 6, ensuring that the extraction solution and the waste lithium-ion battery recycling material fully contact and react. Then, control the heating module 8 to heat the inside of the cup body 1 to accelerate the chemical reaction. The temperature sensor 7 detects the temperature of the extraction solution and feeds it back to the control motherboard 9. The control motherboard 9 controls the heating module 8 to adjust the heating through the temperature control module to achieve constant temperature heating. The operator can open the cup lid 3 or check the reaction through the cup body 1 to determine whether it is a nickel or cobalt hydrometallurgical intermediate.

[0023] In this embodiment, the control panel 4 consists of a power button, a time control knob, a temperature control knob, and a stirring frequency knob. The time control knob has three settings: 10 min, 30 min, and 60 min. The temperature control knob has settings: 25°C, 60°C, and 90°C. The stirring frequency knob has settings: low speed, medium speed, and high speed. The time can be adjusted according to the needs, thus facilitating stirring and heating reactions.

[0024] In this embodiment, the stirring rod 6 is a symmetrical cross shape with an upward curved edge. The inner part of the stirring rod 6 is metal, and the outer layer is a polytetrafluoroethylene layer. The cross-shaped stirring rod 6 has excellent stirring effect and greatly improves the mixing reaction.

[0025] In this embodiment, the heating module 8 is a vortex-shaped graphene heating wire, which has a good heating effect on the extraction solution inside the cup body 1.

[0026] In this embodiment, the control motherboard 9 is a circuit board based on the STM32 series microcontroller, and the circuit board integrates a timing module, a temperature control module and a storage module.

[0027] In this embodiment, the cup body 1 is made of transparent glass, which facilitates the observation of the leaching process. The top edge of the cup body 1 is designed to extend outward to form a spout, which facilitates air leakage.

[0028] Working principle:

[0029] The device is small and portable. Once at the site, open the cup lid 3, pour the appropriate extraction solution into the cup body 1, pour the waste lithium-ion battery recycling material to be identified into the cup body 1, and then put the cup lid 3 back on and keep it sealed by the silicone ring 32.

[0030] Next, press the power button on control panel 4 to power the device via the battery module. Adjust the stirring time, heating temperature, and stirring frequency using the time control knob, temperature control knob, and stirring frequency knob, respectively. Control the leaching conditions by adjusting the time, temperature, and stirring frequency. Press the power button again to send a signal to the control board 9. The control board 9 controls the drive motor 10 to rotate the stirring rod 6, ensuring that the extraction solution fully contacts and reacts with the recycled lithium-ion battery material. Then, control the heating module 8 to heat the inside of the cup body 1 to accelerate the chemical reaction. The temperature sensor 7 detects the temperature of the extraction solution and feeds it back to the control board 9. The control board 9 controls the heating module 8 to adjust the heating through the temperature control module to achieve constant temperature heating. The operator can open the cup lid 3 or check the leaching status through the cup body 1 to determine whether it is a nickel or cobalt hydrometallurgical intermediate.

[0031] In summary, this device, through its integrated extraction, reaction, and detection processes, enables rapid on-site identification and classification of intermediate products from nickel and cobalt hydrometallurgical processes and recycled materials from waste lithium-ion batteries, eliminating the need to send samples to a laboratory for lengthy testing and analysis, thus significantly improving work efficiency and response speed.
