Abstract
Electro-chemical generators of the button type in which a stack of alternate positive and negative electrodes with separators between electrodes of opposite polarity are enclosed between two collectors which serve as terminals of opposite polarity for the generator. The assembly of electrodes, separators and collectors together with requisite electrolyte are held together by a molded insulative plastic frame which has portions overlying the peripheries of the collectors and which also may penetrate to a limited extent in the space between the peripheries of the collectors as by an insulative body encircling the electrode separator assembly. This body may be an electrically insulative ring, or an elastomer seal member.
