Polymer adhesive seals for protected anode architectures

Protected anode architectures for active metal anodes have a polymer adhesive seal that provides an hermetic enclosure for the active metal of the protected anode inside an anode compartment. The compartment is substantially impervious to ambient moisture and battery components such as catholyte (electrolyte about the cathode), and prevents volatile components of the protected anode, such as anolyte (electrolyte about the anode), from escaping. The architecture is formed by joining the protected anode to an anode container. The polymer adhesive seals provide an hermetic seal at the joint between a surface of the protected anode and the container.
