Abstract
The invention relates to a method and device for regenerating zinc for use in electric traction batteries. It consists of putting an alkaline solution of zincate in contact with two electrodes at opposite potentials so that zinc dendrites are deposited on protrusions provided on the negative electrode and so that oxygen is evolved on the positive electrode, said zincate solution being, in a first period, called the deposition period, conveyed towards the ends of the protrusions and at a low speed, then in a second period, called the detachment period, conveyed in the opposite direction and at a sufficiently high speed to detach the dendrites from the protrusions.
