From: A nanotwinned-alloy strategy enables fast sodium deposition dynamics
a Schematic of the electrochemical deposition setup. b–g Time lapse TEM images of Na metal deposition on HPJH-AlSi collector. The nano cells were plated at a current density of 1 mA cm−2 and measured under 25 °C. h Time-resolved evolution of Na size as a function of time during Na deposition on different substrates. i–n The temporal evolution of Na deposition on HPJH-AlSi obtained with MD simulations. The purple spheres, blue frames and pink frames represent deposited Na, Al matrix and nanotwinned Si, respectively. The MD data are provided at https://doi.org/10.24435/materialscloud:r1-e1. Source data for (h) are provided as a Source Data file.
