Abstract

We report on the characteristics of rapid-thermal-annealed LiNi _1-xCo_xO₂ cathode films for all-solid-state thin film microbatteries (TFBs). Scanning electron microscopy, atomic force microscopy, X-ray photoelectron spectroscopy and Auger electron spectroscopy results show that the surface oxide layer formed on the as-deposited LiNi _1-xCo_xO₂ film is completely removed by a rapid thermal annealing process. All-solid-state TFBs consisting of Li/LiPON/LiNi _1-xCo_xO₂/Pt/MgO/Si exhibit stable cyclibility and a high specific discharge capacity of 60.2 μAh/cm²μm. It is concluded that the Li_yNi_1-xCo_xO₂ cathode could represent a promising candidate for a cathode film in TFBs.
