1. An improved battery comprising in combinationa. at least one cell, each cell comprising the combination ofa positive electrode,a negative electrode, andan electrolyte permeable separator between the electrodes, the separator extending beyond the periphery of the electrodes;

  • andb. an intercell connector between each adjacent pair of cells, the connector extending outwardly beyond the periphery of the cell electrodes;

    wherein the improvement comprises having each electrolyte permeable separator consisting essentially of nonconductive, porous, inherently sealable polymeric film material and sealing the separator around its perimeter to the intercell connector, without applying an adhesive material to the surface of the separator periphery, to form a liquid and electrolyte impervious seal.
