Embodiment 1
[0021] (1) The steps of charged crushing of waste batteries under the protection of inert gas and closed atmosphere: 3 kg of waste power ternary lithium batteries are charged and crushed under the protection of carbon dioxide gas and closed atmosphere. The crushing process adopts primary crushing to obtain waste battery scraps, and the crushed battery scraps are transported to the ultrasonic enhanced extraction process by a closed system.
[0022] (2) The step of extracting and recovering the electrolyte by forced extraction method: the broken battery scraps enter the ultrasonic enhanced extraction process, the extraction temperature is 20°C, the extraction time: 60min, and the extraction flow rate: 1:2, so that the electrolysis of the battery scraps Liquid extraction enters the extractant, and through distillation and condensation, the electrolyte is efficiently separated and recovered.
[0023] (3) The step of extracting and recovering the binder by using a new extraction me...
Embodiment 2
[0027] (1) Steps of charged crushing of waste batteries under inert gas protection and airtight atmosphere: 10kg of waste power ternary lithium batteries are charged and crushed under nitrogen protection and airtight atmosphere. The crushing process adopts primary crushing to obtain waste battery scraps, and the crushed battery scraps are transported to the ultrasonic enhanced extraction process by a closed system.
[0028] (3) The step of extracting and recovering the electrolyte by forced extraction method: the battery fragments obtained by crushing enter the ultrasonic enhanced extraction process, the extraction temperature is 22°C, and the extraction time is 10 minutes: the extraction flow rate: 1:5, so that the electrolysis of the battery fragments Liquid extraction enters the extractant, and through distillation and condensation, the electrolyte is efficiently separated and recovered.
