The thin film is composed of fine grains maintaining the crystal structure of the raw powder. In the cyclic voltammogram the thin film electrode shows a anodic peak and a cathodic peak. The initial discharge capacity is gAh cm2 and reversible behavior is observed in charge-discharge profiles. Based on the results the aerosol deposition method is believed to be a potential candidate for the fabrication of thin film electrodes. Keywords thin film aerosol deposition battery Introduction Batteries can be applied to microelectronic and portable devices as power sources 1-3 . Also many endeavors have been made to develop batteries for high power and energy for electric vehicles 4 5 . Although lithium-ion batteries among all other batteries are the most promising type owing to their large energy storage density commercial lithium-ion batteries contain a flammable liquid electrolyte which has induced safety concerns. In order to mitigate the safety issue an all-solid-state battery is a viable candidate as it is composed of thin film electrodes and a solid electrolyte. Moreover the thin film electrode usually is composed of an active material without a binder. Owing to these advantages many studies have been conducted to fabricate all-solid-state batteries .
