Abstract:
1. An electrochemical device, comprising: a housing; a plurality of stacks of electrodes arranged side by side in the housing, each stack comprising an anode electrode, a cathode electrode, and an electrolyte; a plurality of separator sheets, wherein each separator sheet of the plurality of separator sheets extends continuously between at least two of the plurality of stacks, such that each separator sheet is located between adjacent anode and cathode electrodes of each stack; and a plurality of current collectors; wherein: the housing comprises a hermetically sealed, electrochemically inert polymer housing, and the electrodes in each of the stacks are stacked in a prismatic configuration; each current collector of the plurality of current collectors extends continuously between at least two of the plurality of stacks; each separator sheet extends over or under anode boundary areas between adjacent anode electrodes in adjacent stacks; each separator sheet extends over or under cathode boundary areas between adjacent cathode electrodes in adjacent stack; each anode current collector of the plurality of current collectors extends between adjacent anode electrodes in each stack, and over and under the anode boundary areas between adjacent anode electrodes in adjacent stacks; and each cathode current collector of the plurality of current collectors extends between adjacent cathode electrodes in each stack, and over and under the cathode boundary areas between adjacent anode electrodes in adjacent stacks.
