Abstract

Disclosed are a system and methods for preventing dendrite growth in an electrochemical cell through the use of a protective layer. The electrochemical cell may comprise an anode, a cathode, an electrolyte, and a protective layer, wherein the protective layer is capable of producing a voltage. The voltage produced can selectively shield metal ions from certain regions of the protective layer. This shielding can result in a more uniform flux of metal ions being transferred across the electrode-electrolyte interface in subsequent electrodeposition and electrodissolution processes. As a result, an electrode with such a protective layer can exhibit improved performance and durability, including markedly lower overpotentials and largely improved metal (e.g., lithium) retention.
