Electrolyte separation and recovery method and system for waste batteries

Abstract

The invention relates to the technical field of electrolyte recovery, in particular to an electrolyte separation and recovery method and system for a waste battery, and the method comprises the following steps: S1, determining the residual electric quantity of a battery cell; s2, determining whether the residual electric quantity is qualified or not based on the concentration distribution characterization value, and correcting the residual electric quantity based on a residual electric quantity disqualification condition; s3, under the condition that the residual electric quantity is determined to be qualified, whether deep discharging is carried out on the battery cell or not is determined based on the residual electric quantity, and a to-be-disassembled battery cell is obtained; s4, determining an export mode of the electrolyte of the to-be-disassembled battery cell based on the packaging integrity characterization value; and S5, in the corresponding export mode, determining whether the electrolyte export is complete based on the flow characterization value of the electrolyte, and adjusting the export duration of the electrolyte or adjusting the preset integrity characterization value based on the electrolyte export incomplete condition. The lead-out efficiency of the electrolyte is improved.
