Abstract

An edge seal for a lithium or other consumable metal anode comprises a hydrophobic, chemically inert polymer coating having a high ratio of flexural modulus to flexural strength, a low Izod impact value, and low elongation properties. The seal is applied to the edge of the anode under an atmosphere of gas which is non-reactive with the anodic metal.
