Extended Data Fig. 5: Domain maps and correlation functions for various lithiation rates at room temperature.

a–f, Representative domain maps (top row) and SEM images (bottom row) of Si microlattice samples lithiated at different rates at room temperature. Panels c and d show two samples for C/6, illustrating that nominally identical Si microlattices at the same lithiation conditions produce different domain patterns. g, Correlation functions at different lithiation rates with two samples per rate at room temperature. h, A zoomed-in plot of part of g, focusing on the initial decay of the correlation functions. i, Averaged correlation function at different lithiation rates from two samples per rate at room temperature. Data points in g–i are connected by straight lines.
