From: Monodisperse Porous Silicon Spheres as Anode Materials for Lithium Ion Batteries
TEM images of (a) monodisperse solid silica spheres (SS) and (b–d) monodisperse porous silicon spheres (MPSS), respectively. (e) BET surface area measurements of SSs and MPSSs with type IV N2 adsorption and desorption isotherms. Inset shows the pore size distribution of MPSSs.
