ELECTROCHEMICALLY DEPOSITED LiCoO_2 FILM ON PLATINUM METAL SUBSTRATE UNDER HYDROTHERMAL CONDITION

摘要

Film of LiCoO_2 as cathode material for rechargeable lithium microbatteries has been fabricated on the platinum metal substrate by electrochemical-hydrothermal method in concentrated LiOH solution at 200 deg C as Soft Solution-Processing. The film fabrication has been understood in terms of dissolution of cobalt metal powders and subsequent oxidative deposition on the substrate. The film structure was characterized using scanning electron microscope, X-ray diffraction analysis, X-ray photoelectron spectroscopy and micro-Raman spectroscopy.
