A method and system for manufacturing a thin-film battery and a battery structure formed with the method utilizes a plurality of deposition stations at which thin battery component films are built up in sequence upon a web-like substrate as the substrate is automatically moved through the stations. At an initial station, cathode and anode current collector film sections are deposited upon the substrate, and at another station, a thin cathode film is deposited upon the substrate so to overlie part of the cathode current collector section. At another station, a thin electrolyte film is deposited upon so as to overlie the cathode film and part of the anode current collector film, at yet another station, a thin lithium film is deposited upon so as to overlie the electrolyte film and an additional part of the anode current collector film. Such a method accommodates the winding of a layup of battery components into a spiral configuration to provide a thin-film, high capacity battery and also accommodates the build up of thin film battery components onto a substrate surface having any of a number of shapes.
A method for building up thin-film battery components in a layup arrangement wherein the layup includes a cathode film, an electrolyte film and a lithium anode film, the method comprising the steps of:
A method for constructing a thin film battery including the steps of:
In a rechargeable, thin-film battery including a substrate surface, a thin cathode film overlying the substrate surface, a thin electrolyte film overlying the cathode surface and a thin lithium anode film overlying the electrolyte film, the improvement characterized in that:
