Abstract
The invention relates to an electrolytic resistor comprising a water-repellent insulating tube through which there flows an alkaline solution containing a suspension of zinc. The positive end of the resistor has a metallic grid suitable for trapping the zinc particles, and the negative end has either an air electrode or a ring made of a metal having, more especially, high hydrogen supertension, this ring itself possibly having holes or projections suitable for promoting the progressive deposition of zinc dendrites. The invention is used in zinc-air storage cells.
Claims15
An electrolytic resistor of the type containing a flow of an alkaline aqueous solution including a metal in suspension and a hydroxide of said metal in solution, said resistor comprising a tube made of an electrically insulative material for containing said flow, the positive end of said electrolytic resistor comprising a grid made of a conductive material capable of retaining particles of said metal in suspension and the negative end of said resistor comprising an inner porous insulator and hydrophilous separator layer, an intermediate electrode layer capable of consuming oxygen in the air and of producing hydroxide ions therefrom, and an outer conductive grid layer.
An electrolytic resistor having a tube made of an electrically insulating material and containing a flow of an alkaline aqueous solution including a metal in suspension and a hydroxide of said metal in solution, the positive end of said electrolytic resistor comprising a grid made of a conductive material which is capable of retaining particles of said metal in suspension and the negative end of said resistor comprising a conductive material having a conductive material having a high hydrogen overpressure and free from inclusions of elements which are liable to form intermetallic compounds with said metal in suspension so that particles of metal are deposited on its surface by electrolysis of said hydroxide and are then separated and drawn away by flow of said alkaline solution.
