Embodiment 1

[0026] Embodiment 1: the recycling method of lithium ion capacitor of the present invention, its process reference figure 1 As shown, the method includes the following specific steps in turn:

[0027] (1) Test the voltage of the discarded lithium-ion capacitor PACK module with a multimeter. If there is a voltage display, proceed to step (2); if there is no voltage display, proceed to step (3) directly;

[0028] (2) Discharge the recovered lithium-ion capacitor PACK module to a safe voltage or below through a charging and discharging device. The safe voltage is nV, and n is the number of batteries. After discharging, the voltage of the lithium-ion capacitor PACK module is E ≤nV, if the number of batteries is 4, the safe voltage value is 4 volts, and the voltage E of the lithium-ion capacitor PACK module after discharge is ≤4 volts;

[0029] (3) Disassemble the lithium-ion capacitor PACK module from step (1) without voltage display and step (2) discharge treatment to obtain a l...

Abstract

Disclosed is a method for recycling a lithium-ion capacitor. The method mainly comprises the steps that the voltage of a PACK module is examined; discharging operation is conducted until the voltage is equal to the safety voltage; the PACK module is disassembled; the voltage of the single lithium-ion capacitor is examined; discharging operation is conducted until the voltage is equal to the safety voltage; the single lithium-ion capacitor is crushed; incineration is conducted; and aluminum and copper are recovered, and dust is buried. The method is simple, economical and effective, easy and fast to operate, high in practicability and applicable to industrialization, achieves the purpose of being free of pollution and the purpose of zero discharge, and can conduct recycling on aluminum metal and copper metal.

Description

technical field [0001] The invention relates to a method for recycling an energy storage device, in particular to a method for recycling a lithium ion capacitor. Background technique [0002] Batteries are one of the most important power sources in modern industry, and can be widely used in different fields such as lighting, electric vehicles, automobiles, communications, computers, household appliances, and military affairs. According to the regulations on hazardous waste control in the Basel Convention, many types of waste batteries are hazardous waste, which contain heavy metals such as mercury, cadmium, zinc, manganese, copper, silver, lithium, nickel, lead, cobalt and other heavy metal elements as well as acid, Harmful substances such as alkali. If it is discharged into the environment without recycling, it will bring immeasurable harm to the environment and society. [0003] According to preliminary statistics, the lead consumed by lead-acid batteries accounts for ab...
