Title: BATTERY RECOVERY METHOD
Abstract:
The present invention relates to a method for restoring a battery, comprising the steps of: checking the appearance of the battery; measuring whether the battery is recoverable; forming a perforation hole in the battery; discharging an electrolyte and sludge from the perforated battery; purifying the electrolyte; measuring the specific gravity of the purified electrolyte, adjusting the specific gravity of the battery, and injecting the electrolyte; and sealing the perforation hole. The method further comprises: a seating step of placing the battery determined to be recoverable in a cleansing box; a binding step of binding the battery seated in the seating step to the cleansing box; and a vibrating step of vibrating the cleansing box by means of an oscillator. As such, an effect is achieved whereby the sludge attached to each electrode plate is cleanly removed by ultrasonic waves generated from the oscillator.
