Abstract:
A method for manufacturing a thin-film battery comprising the steps of:a. through a first mask, depositing a first metal as an adhesion layer on a substrate; b. through said first mask, depositing a second metal as a current collector over said adhesion layer; c. through said first mask, sputtering a cathode layer in an argon-oxide gas on top of said current collector while rocking said substrate in an oscillatory fashion; d. heating said substrate in a dry environment of less than 1% humidity to an elevated temperature for a fixed period of time; e. through a second mask, sputtering a thin film solid state electrolyte material onto said cathode layer while rocking said substrate in an oscillatory fashion, thereby forming an electrolyte layer; f. evaporating an anode layer over said electrolyte layer; and g. packaging and sealing the resulting structure.
