Freeform batteries

A battery comprising:

• a metal can housing the battery, the metal can comprising a top can having a top surface and a bottom can having a bottom surface, the metal can further comprising a first flange extending from a first end and a second flange extending from a second end;
• a plurality of anodes;
• a plurality of cathodes, each cathode between two of the plurality of anodes;
• a plurality of separators, each around a corresponding cathode;
• an electrical terminal on the first flange;
• and
• a fill hole to provide access to an interior of the metal can on the second flange.

A method of forming a battery, the method comprising:

• providing a first non-planar surface;
• providing a stack of components on the first non-planar surface;
• providing a second non-planar surface to the stack of components such that the stack of components is between the first non-planar surface and the second non-planar surface;
• applying heat to the stack of components;
• and
• applying pressure to the stack of components,
• wherein the stack of components comprises a plurality of anodes separated from each other by cathodes in a plurality of cathodes.
