Figure 1

(a–c) SEM images of the Si active materials used in this study. The active materials were (a) Si microparticles, (b) Si nanoparticle aggregates, and (c) Si thin flakes. (d) Binder-free Si anode fabrication process via the electrophoretic deposition (EPD) method. Here, Si thin flakes were employed as the Si active material. (e) Illustration of a typical Li-ion battery system with a binder-free Si thin flake anode for in situ SEM.
