From: A nanotwinned-alloy strategy enables fast sodium deposition dynamics
a Schematic illustration of the preparation process of different Al-Si alloys. b TEM image of the HPJH-AlSi. c Fraction of NT-Si supported on HPJH-AlSi and HPA-AlSi statistically counted from TEM images. d Crystal structure of the NT-Si and Al matrix. The dark blue and light blue spheres denote Si and Al elements, respectively. e High-resolution transmission electron microscopy (HRTEM) images of NT-Si and the corresponding elemental mapping. f Atomic resolution HAADF image of the (111) Al taken along the [011] axis. g Atomic resolution HAADF image of the (111) NT taken along the [011] axis. h Geometric phase analysis map (horizontal shear strain, εxy) for HRTEM of NT-Si. Source data for (c) are provided as a Source Data file.
