- Abstract
- Aerosol flame pyrolysis deposition method was applied to deposit the oxide glass electrolyte film and LiCoO2 cathode for thin film type Li-ion secondary battery. The thicknesses of as-deposited porous LiCOO2 and Li2O-Li2O-B2O3-P2O5 electrolyte film were about 6 mu m and 15 mu m, respectively. The deposited LiCoO2 was sintered for 2 min at 700 degrees C to make partially densified cathode layer, and the deposited Li2O-P2O5-B2O3 glass film completely densified by the sintering at 700 degrees C for 1 h. After solid state sintering process the thicknesses were reduced to approximately 4 mu m and 6 mu m, respectively. The cathode and electrolyte layers were deposited by continuous deposition process and integrated into a layer by co-sintering. It was demonstrated that Aerosol flame deposition is one of the good candidates for the fabrication of thin film battery.
