TH163148A - Electrolyte cells for electrolytic metal extraction - Google Patents

Abstract

The invention involved a cell for electrolytic metal extraction that was equipped with One useful device for preventing the reverse effects of growing up dendrite on the Adheres to the cathode side The cell consists of a scene with a porous conductivity. That has been positioned Between anode and cathode That can stop the growth of the Dendrite And avoid those things Arrive at the anode surface
