This presentation will discuss the latest findings in regards to the concept of mediating nucleation and growth of a solute crystal inside a liquid metal electrode through heterogeneous electrochemical reduction reactions at the electrolyte/electrode interface. The focus will be to compare/contrast experimental and modeling data that pertain to the flux conditions that favor and inhibit nucleation and crystal growth steps. Two systems will be discussed. First, conditions that favor large-grain crystal growth from a bulk liquid pool electrode will be discussed. Second, flux conditions that permit a single crystal to grow from a microscopic liquid metal droplet will be presented. The possibility of using AC amperometry in both systems to initiate and affect crystal growth will also be discussed.
