Abstract: A battery electrode includes a first metal foil, a second metal foil, and a thermoplastic polymer layer between the first metal foil and the second metal foil. The battery electrode also includes a first coating adjacent to the first metal foil such that the first metal foil is between the thermoplastic polymer layer and the first coating. The battery electrode also includes a second coating adjacent to the second metal foil such that the second metal foil is between the thermoplastic polymer layer and the second coating.
