Abstract

A battery structure using a plurality of cells in stacked array wherein each cell comprises an anode having a centrally positioned opening and flange positioned about the periphery of the opening for contact with the periphery of the opening of an adjacent anode. Each cell includes a pelletized depolarizer material that extends beyond the perimeter of the anode but coextensive with the anode flange. An outer encasement member receives the stacked array so that the depolarizer pellets are in electrical contact with the inner surface of the encasement. The encasement means includes a top member having an opening located to align with the openings in the anode and anode collector positioned through said opening in the top member and electrically insulated therefrom and in electrical contact with each of said anode flanges.

Dependent claims

A primary battery comprising:

A. an electrically conductive encasement means having a base portion, said base portion including a first insulating means;
B. a stacked array of cells extending from said first insulating means to the top of the encasement means, each of said cells consisting essentially of an anode and a pelletized depolarizer, said depolarizer being in direct contact without any separating layer, except an in situ formed electrolytic layer, with said anode and the anode of an adjacent cell, said anode and depolarizer of each cell being relatively positioned so that said cell is in electrical contact with the inner surface of said encasement means through said depolarizer of each cell;
C. a second insulator means positioned substantially coextensively over said array;
D. means for electrically connecting each of said anodes in parallel;
and
E. an electrically conductive top means sealingly attached to said encasement means and including a terminal electrically insulated therefrom, said terminal being electrically connected to said means for electrically connecting each of said anodes.
