From: Revealing lithium–silicide phase transformations in nano-structured silicon-based lithium ion batteries via in situ NMR spectroscopy

Figure 1

(a) Planar view, (b) cross sectional view and (c) a magnified image of (b). The scale bars for (a–c) are 50, 15 and 500 nm, respectively. (d) Schematics of the SiNW-composite based cell and the set-up for the in situ7Li NMR measurements. The cell design comprises Si nanowires (SiNW), a carbon fibre based gas diffusion layer support (CFGDL), electrolyte (1 M LiPF6 in ethylene carbonate (EC) and dimethyl carbonate (DMC) solution), a porous glass fibre mat and a Cu mesh sealed in a polyester bag.
