Fig. 3

a In situ measurement of thickness evolution of a control SiO electrode and a SiO electrode with the elastic GPE in the initial three lithiation/delithiation cycles at a current density of 0.3 mA cm−2 between 0.01 and 1.5 V. The mass loading of SiO electrodes is 3.7 mg cm−2 and the copolymer amount is 0.4 mg cm−2. b, c Top-view (b) and cross-sectional (c) SEM images of the control SiO electrode after 10 cycles. d, e Top-view (d) and cross-sectional (e) SEM images of the SiO electrode with the elastic GPE after 10 cycles. Scale bars: 100 μm (b, d), 20 μm (insets in b, d), 50 μm (c, e), 20 μm (insets in c, e).
