Problems solved by technology
[0010] In order to effectively recycle lithium-ion batteries, reduce pollution, and improve energy utilization, people have studied more lithium-ion battery recycling methods and devices, which mainly include the following steps, discharge-crushing-sorting, by soaking the battery in sodium chloride Discharge in the solution, the discharge time is longer, generally more than 7 days, it needs to be drained after discharge, and continuous work cannot be achieved, and because the voltage of each lithium-ion battery is different during the discharge process, the concentration of free ions in each part of the solution Different, affect the discharge efficiency

Description
technical field [0001] The invention relates to the field of waste lithium ion battery recovery, in particular to a waste lithium ion battery recovery treatment device. Background technique [0002] Lithium-ion battery: It is a secondary battery (rechargeable battery) that mainly relies on lithium ions to move between the positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: when charging, Li+ is deintercalated from the positive electrode, intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. [0003] Lithium-ion batteries have high energy density and high average output voltage. Small self-discharge, good battery, below 2% per month (recoverable). There is no memory effect. The wide working temperature range is -20℃~60℃. Excellent cycle performance, fast c...
