Figure 3. Characterization of Si anodes with CNTs and PAM-g-CNTs. Li⁺ diffusion coefficients, which were calculated from GITT during (A) the lithiation and (B) delithiation; (C) SAICAS horizontal force profiles of the electrode; (D) Average adhesion force based on peel-off test results. CNTs: Carbon nanotubes; PAM-g-CNTs: polyacrylamide-grafted CNTs; GITT: galvanostatic intermittent titration technique; SAICAS: surface and interfacial characterization analysis system.
