Battery repair is mainly aimed at a series of problems (more than 90% of batteries are due to these problems), such as battery vulcanization, active material shedding, plate softening and hardening. If there are broken bars, broken grids, serial holes in plates, leaking shells and other hardware damages, they can be repaired first and then repaired to reach a perfect value. Development of battery repair technology: With the development of technology and the improvement of living standards, batteries are increasingly used in all fields of life, especially electric vehicles and automobiles. The rapid development of electric vehicles and automobile industry provides a broader development prospect for the battery industry. However, due to the improper operation of people and some defects of the battery itself, the battery capacity decreased and the service life was greatly shortened, so the battery repair technology came into being. Battery repair technology has gone through the stages of adding acid, charging with high current, hydrotherapy, activation, scanning, broadband, high frequency, resonance and pulse. These early technologies were gradually eliminated. At present, the repair technology of microcomputer positive and negative ion batteries is more advanced, and the repair technology of composite ions is becoming more and more perfect.
