A dry powder deposition technique, namely electrostatic spray deposition (ESD), has been investigated for cathode fabrication of Li-ion battery. The specific features focused in this study were to prepare core/shell composite particles and examine their applicability for ESD. LiCoO2 (LCO) was chosen as a cathode active material. Around the LCO particle, carbon nanoparticles as conductive additive were coated, followed by PMMA nanoparticles as binder additive, producing core/shell composite particles. The nanoparticle-coated unevenness on the LCO was capable of significantly improving the fluidity of the cohesive LCO particles. The composite particles also showed a good electrostatic charging ability. In addition, the PMMA nanoparticles in the outermost layer of the composite particles played a crucial role on a stable electrostatic deposition. Thus, LCO-based cathode film was successfully fabricated by ESD using the composite particles.
