Figure 7
NMF analysis using four components. (a) Component PDFs (G versus r). (b) Reconstruction error as a function of the number of components. (c) Top: phase-specific atomic pair correlations of the bronze, lithiated bronze, lithiated anatase and anatase phases, from denoised operando PDF data. Middle: NMF weights. Bottom: voltage profile. The electrochemical potential is shown as a function of the lithiation degree (state of charge).
