Reinforced consumable electrode, electrochemical cell and method
First Claim
Patent Images
1. An electrode suitable for use in an electrochemical cell, comprising:
- (a) a solid body of a reactive metal which is consumable by reaction with a liquid electrolyte, said body defining at least one surface to be contacted by said electrolyte during operation;
(b) a fibrous network of electrically insulating reinforcing material at least partially embedded in said body with at least a portion of said network disposed in said body in close proximity to said surface for contact with said electrolyte as metal at said surface is consumed by reaction with said electrolyte.

Abstract
A consumable metal electrode incorporates a fibrous reinforcing network of electrically insulating material extending through at least a portion of the body of the electrode and disposed in close proximity to a surface of the electrode which will be contacted by liquid electrolyte and eroded during operation of an electrochemical cell incorporating the electrode. Local turbulence is generated by the fibrous network at the electrode surface during operation of the cell in order to maximize electrical output.
