Abstract:
1. A conformable battery, capable of being manufactured to a desired shape, comprising: an outer casing having at least an upper and a lower face plate and at least one perimetric wall; at least two compartments, each of said at least two compartments isolated from each of the other of said at least two compartments by a grid of walls extending from said upper face plate to said lower face plate and connecting to said at least one perimetric wall, thereby dividing an internal volume of said battery into said at least two compartments and increasing the battery's structural stiffness and ability to sustain increased internal pressure; each of said at least two compartments containing therein an electrochemically active plate stack comprising positive and negative electrodes and separators immersed in electrolyte; a network of electrical conductors providing electrical connection between said plate stacks in each of said at least two compartments; and a reservoir containing an additive, wherein each of said at least two compartments are in fluidic communication with said reservoir such that said additive can flow from said reservoir to each of said at least two compartments, and expelling structure for enabling said additive within said reservoir, upon activation of said expelling structure, to be forcibly expelled from said reservoir and into each of said at least two compartments.
