Fabrication of composite electrodes. a Composite electrode preparation from Si/MXene ink-based slurry. b The slurry drying process and c scheme displaying the resulting Si/MXene composite. The MXene nanosheets form a continuous scaffold and enable the formation of a thick electrode. d Top-view and e cross-sectional scanning electron microscopy (SEM) images of nSi/MX-C electrode, showing the Si nanoparticles are well wrapped by the MX-C nanosheets in a manner of sandwiching (scale bar for d and e = 1 µm). f Top-view SEM image of Gr-Si/MX-C electrode, indicating that the Gr-Si particles are well wrapped by the continuous MX-C network (scale bar = 1 µm)
