An electronical cell is provided that includes: a can having an open end and a closed end; and a cover positioned across the open end of the can, the cover and can defining an internal volume within the can in which electrochemicall y active materials including at least positive and negative electrodes and an electrolyte are contained. In one embodiment, the internal volume is at leas t 88.4 percent of the total volume of the battery. In order embodiments, the internal volume is at least 89.2 percent (D-sized batteries), at least 83.2 percent (C-sized batteries), at least 82.0 percent (AA-sized batteries) and at least 78.7 percent (AAA-sized batteries), of the total volume of the battery . In further embodiments, the internal volume is at least 44.67 cm3 (D-sized batteries), at least 20.21 cm3 (C-sized batteries), at least 6.47 cm3 (AA- sized batteries) and at least 2.811 cm3 (AAA-sized batteries). |
