NOVELTY - A thin-film electrochemical cell structure comprises a cathode sheet layer comprising a series of discontinuous cathode sheets; a gap defined between adjacent ones of the cathode sheets; and a solid electrolyte layer contacting a second surface of a cathode layer of the cathode sheet layer and extending across the gaps defined between the adjacent cathode sheets.    USE - For solid-state, thin-film batteries.    ADVANTAGE - The cell structure incorporates a unique discontinuous cathode sheet structure (25a, 25b).    DETAILED DESCRIPTION - A thin-film electrochemical cell structure comprises a cathode sheet layer comprising a series of discontinuous cathode sheets; a gap (30) defined between adjacent ones of the cathode sheets; and a solid electrolyte layer (22) contacting a second surface of a cathode layer of the cathode sheet layer and extending across the gaps defined between the adjacent cathode sheets. Each cathode sheet comprises the cathode layer; and a current collector layer (26) having a first surface contacting a first surface of the cathode layer.    INDEPENDENT CLAIMS are included for:    (a) a method of producing a series of thin-film electrochemical cell structures, comprising cutting a web (cathode web), having a cathode layered structure moving at a first speed into a series of cathode sheets; moving a web (electrolyte web) of a solid electrolyte at a second speed equal to or greater than the first speed; laminating each cathode sheet moving at the first speed with the electrolyte web moving at the second speed to produce a first laminate structure having a space between adjacent cathode sheets; and laminating a web (third web) of a material with the first laminate structure such that the cathode sheets are disposed between the electrolyte web and the third web; and    (b) an apparatus for producing a series of thin-film electrochemical cell structures, comprising a first feed station that feeds the cathode web at the first speed; a rotary cutting station that receives the cathode web from the first feed station and rotatably cuts the cathode web into the series of cathode sheets; a second feed station that feeds the electrolyte web at the second speed; a first rotary lamination station that receives the electrolyte web and the cathode web and laminates each cathode sheet with the electrolyte web to produce the first laminate structure; a third feed station that feeds the third web of a material; and a second rotary lamination station that receives the third web and the first laminate structure and rotatably laminates the third web with the first laminate structure.
