Electrochemical Formation of Pb Microwires with Tunable Morphology on Liquid Metal Electrodes.

Liquid metal electrodes based on Ga are an emerging area of interest given their fluid properties which can have significant impact on electrochemical processes. Here we study metal electrodeposition, namely lead electrodeposition on the liquid metal electrodes, gallium (Ga) and galinstan (GaInSn), which was performed in two different Pb electrolytes (PbCl and Pb(NO)) to investigate any differences in the nature of the electrodeposit. Cyclic voltammetry and chronoamperometry were used to study the characteristics, kinetics, and nucleation and growth mechanisms of the electrodeposition process.
