Figure. Volume change monitoring during the CV of the graphite anode by Operando SICM (IMAGE)
Caption
(a) Scheme of the single point measurement. (b) Time course of the potential, height, state of charge, carbon anode current, and SICM current during the CV. (c) Scheme of the continuous one-line scanning measurement. (d) Time course of the one-line height image, carbon anode current, and SICM current during the CV. The sweep rate was 0.3 mV/s. (e) SICM ion current XZ images, where the image points are shown in Fig. 5d. Hopping amplitude and the falling rate of SICM were 2000 nm and 30 nm/ms, respectively. The nanopipettes radii were 50 nm and filled with 1.0 M LiClO4 in EC / DEC = 1 / 2 (v/v). The height monitoring was acquired by applying the constant voltage of 0.7 V vs. Li/Li+.
