1. A method for constructing flat battery units comprising the steps of:

  • providing first current collectors, each having a lengthwise and widthwise dimension;

    providing a continuous carrier sheet of electrically insulative material having a widthwise dimension at least as great as the widthwise dimension of said first current collectors;

    intermittently depositing in predetermined spaced sequential alignment upon one side of said continuous carrier sheet said first current collectors;

    thereon depositing in a predetermined sequence superposed on each first current collector electrolyte, anode materials, cathode materials, separators and intercell connectors; and

    thereon depositing a second current collector to form discrete electrically coupled flat cell assemblies; and

    cutting said continuous carrier sheet between said discrete cell assemblies to provide discrete battery units comprising a sheet of electrically insulative material at least coextensive in size with a first current collector.
