A method for constructing flat batteries having improved peripheral seals. These batteries are characterized in incorporating polymeric intercell connectors, outer collector assemblies including an externally disposed sheet terminal-current collector and sheet separator components associated with thermal sealing material, the peripheries of the seal material extending outwardly from the corresponding peripheries of the current collectors and intercell connectors. To effect a seal of improved integrity as well as enlarged size, a cover sheet of material dimensionally stable at temperatures whereat the seal material and the polymeric connectors are dimensionally unstable is placed over the current collector and seal portions with which a thermal sealing bar would otherwise come in contact.
