1. In a thin planar battery having a multiplicity of discrete electrically conductive polymeric layers arranged in cooperative electrical association with one another to form a multicell battery, the improvement comprising:

  • continuous frame-type electrically insulative sheet sealing means providing an opening defined by an inner border and having a first surface bonded to a peripheral surface of each discrete electrically conductive polymeric layer, said sheet sealing means extending outwardly from the periphery of the so bonded electrically conductive layer to define a continuous border sealing portion; and

    discrete, sheet-type separator means positioned between the electrically conductive layers and having a periphery extending beyond the sealing means inner opening and within said border sealing portion which periphery is bonded to the surface of the sealing means opposite the first surface.
