Multi-Field Synergistic Restoration Method for Retired Batteries, and Devices

Abstract

A multi-field synergistic repair method for retired batteries and devices thereof relates to the technical field of battery repair, which comprises the following steps: charging and discharging a retired battery in sequence; the charging and/or discharging are performed under the action of synergistic fields to obtain a regenerated battery; the synergistic fields are at least one of magnetic fields, pressure fields or temperature fields; the charging and discharging are cycled 1 time to 20 times in total. The invention solves the problems of complex process, high cost and poor effect of existing battery recycling processes; the battery performance can be restored to more than 80% of the initial capacity of the new battery, realizing the regeneration of lithium-ion batteries and sodium-ion batteries; the battery regeneration method has the advantages of no need to disassemble the battery, short time, low energy consumption, low cost, and zero emission.
