From: Revealing the aging process of solid electrolyte interphase on SiOx anode
a, b Proposed schematic illustration of electrode evolution without and with a confining layer, respectively. c Comparison of cycling performance between cells with and without the graphite confining layer. d Cross-sectional SEM images of SiOx electrodes without graphite confining layer, where a thick SEI can be observed. e Cross-sectional SEM images of SiOx electrodes with a graphite confining layer, where thinner SEI is grown on SiOx particles. Scale bars in d and e = 5 um. f Swelling ratios of SiOx and Gr-SiOx electrodes during the initial 3 cycles.
