1. A method of manufacturing a thin film battery comprising the steps of:

  • (a) providing a substantially planar cathode current collector having two oppositely disposed generally planar surfaces;

    (b) depositing a first cathode layer upon one cathode current collector surface;

    (c) depositing a second cathode layer upon the other cathode current collector surface;

    (d) depositing a first electrolyte layer upon the first cathode layer;

    (e) depositing a second electrolyte layer upon the second cathode layer;

    (f) depositing a first anode layer upon the first electrolyte layer, and (g) depositing a second anode layer upon the second electrolyte layer.
