Batteries and battery manufacture methods

Batteries and associated methods of manufacture are described. According to one aspect, a battery includes a battery case, an anode within the battery case, a cathode within the battery case, a separator configured to electrically insulate the anode from the cathode and the battery case, an electrolyte in contact with the anode and the cathode, and first and second terminal connections connected with respective ones of the anode and the cathode, and wherein the first and second terminal connections are configured to conduct electrons between the anode and the cathode via a load which is external of the battery case.
