From: A nanotwinned-alloy strategy enables fast sodium deposition dynamics
a The slope value of the linear relationship between LSV peak current and scan rate. b MSD simulation of Na on different collectors. c The diffusion pathway and calculated energy profile of Na along the diffusion path of Na on the NT-Si. The blue spheres and yellow spheres represent Si and Na atoms, respectively. d Deposition morphology phase map as a function of Damköhler number. e Plots of t/tm and (j/jm)2 in comparison with theoretical 3D models for a Na cell using Al, HPA-AlSi and HPJH-AlSi collector.
