| Abstract | Abstract A novel nanoporous tree-like SiO 2 film was synthesized by a sol–gel assisted electrostatic spray deposition (SG-ESD) approach. The sol–gel process employed was better to create SiO 2 with linear cross-link chains for the electrostatic spray deposition. From electron microscopic study, it was found that the as-deposited SiO 2 films possess nanoporous tree-like morphology in macroscale; and monodispersed hollow nanoporous spherical structure in microscale. The formation of the nanoporous “tree” structure is related to the preferential landing of droplets on the substrate and the electrostatic repulsion force among landing droplets during the ESD process. The catalytic effect of hydrochloric acid in the sol–gel system contributes to the formation of the hollow and porous structured SiO 2 spheres. The charge-discharge characteristics of the porous SiO 2 as an anode for Li-ion batteries were briefly evaluated and good long-term cycle performance was reached. |
