How does the new process work?
The essential step in the new process is applying galvanic corrosion using a restoration solution. Galvanic corrosion occurs when two dissimilar materials are in contact within an electrolyte environment, leading to the selective corrosion of one metal to protect the other.

“The bromine in the restoration solution initiates spontaneous corrosion upon contact with the aluminum in the spent battery. During this process, electrons are released from the corroded aluminum and subsequently transferred to the spent cathode material,” the press release states.
