Abstract<\/h3>\n
\n

By starting from fundamental principles, the heterogeneous nucleation and growth of electrodeposited anode materials is analyzed. Thermodynamically, we show that an overpotential-controlled critical radius has to be overcome in order for dendrite formation to become energetically favorable. Kinetically, surface tension and overpotential driving forces define a critical kinetic radius above which an isolated embryo will grow and below which it will shrink. As a result, five regimes of behavior are identified: nucleation suppression regime<\/em>, long incubation time regime<\/em>, short incubation time regime<\/em>, early growth regime<\/em>, and late growth regime<\/em>. In the nucleation suppression regime<\/em>, embryos are thermodynamically unstable and unable to persist. For small overpotentials, below a critical overpotential, 2\u03b7\u25cb<\/sub>, and between the thermodynamic and kinetic critical radius, a metastable regime exists where the local electrochemically enabled Gibbs-Thomson interactions control the coarsening of the embryos, thus defining the long incubation time regime<\/em>. In addition, very broad nuclei size distributions are favored. For large overpotentials, above 2\u03b7\u25cb<\/sub>, a short incubation time regime<\/em> develops as a result of the small energy barrier and large galvanostatic driving forces. In addition, very narrow size distributions of nuclei are favored. In the early growth regime<\/em>, thermodynamically and kinetically favored nuclei grow to reach an asymptotic growth velocity. Finally, in the late growth regime<\/em>, morphological instabilities and localized electric fields dominate the morphology and microstructural evolution of the deposit.<\/p>\n<\/div>\n
