Disclosed are methods for pre-conditioning or pre-treating the surface of a metal (e.g., lithium) electrode such that the cycle life and efficiency of the electrode within an electrochemical cell are improved through the prevention of dendrite growth. The pretreatment process includes the use of an alternating current to modify the surface properties of the metal electrode, such that a more uniform flux of metal ions is transferred across the electrode-electrolyte Interface in subsequent electrodeposition and electrodissolution processes. As a result, an electrode treated with such a process exhibits improved performance and durability, including markedly lower overpotentials and largely improved metal (e.g., lithium) retention in strip plate tests as compared with untreated electrodes.
