Abstract
A hybrid energy storage device (10) including first, second, and third electrodes (20, 25, 30), a first electrolyte (35) disposed between the first and second electrodes (20, 25), and a second electrolyte (40) disposed between the second and third electrode (25, 30). The first electrode (25), the first electrolyte (35), and the second electrode (25) form a battery, and the second electrode (25), the second electrolyte (40), and the third electrode (30) form a capacitor. The first and third electrodes (20, 30) are directly connected together so that the battery and capacitor are in parallel within the hybrid energy storage device (10).
