PROCESS FOR PRODUCING THIN FILM TYPE LITHIUM ION SECONDARY CELL BY USING DROP CHEMICAL DEPOSITION

摘要

PURPOSE: A process for producing a thin film type lithium ion secondary cell is provided to improve the initial discharge capacity and discharge capacity reduction of the secondary cell. CONSTITUTION: The process for producing a thin film type lithium ion secondary cell by using drop chemical deposition comprises the steps of: applying a high frequency to a cathode material precursor solution to generate a drop and depositing the cathode material onto a cathode collector; applying a high frequency to an electrolyte solution precursor to generate a drop and depositing the electrolyte onto the cathode material; depositing an anode material onto the electrolyte; and depositing an anode collector onto the anode material.
