Direct regeneration method has been widely concerned by researchers in the field of battery recycling because of its advantages of in situ regeneration, short process and less pollutant emission.
Battery regeneration is a process that consists of sending high-powered electrical pulses that break down the crystalline layer formed by amorphous lead sulphate. A traditional charger cannot allow this process, while a specially designed device produces convincing results.
The latest research status of direct regeneration of spent lithium–ion batteries was reviewed and summarized in focus. The application examples of direct regeneration technology in production practice are introduced for the first time, and the problems exposed in the initial stage of industrialization were revealed.
Direct regeneration method Direct regeneration is a green, economical, and feasible method that uses a physical method to directly regenerate the active substance of the cathode.
Traditional recycling methods have problems with high energy consumption and secondary pollution. In contrast, direct regeneration extends battery life by repairing degraded cathode materials and retains battery energy to the maximum extent. This method includes technologies such as chemical lithiation and recycling of waste graphite.
