HIGH PERFORMANCE ENERGY STORAGE DEVICES

摘要

A lead-acid battery comprising at least one lead-based negative electrode (1); at least one lead dioxide-based positive electrode (2); at least one capacitor electrode (3); and electrolyte (7) in contact with the electrodes (1, 2) wherein a battery part is formed by the lead based negative electrode (1) and the lead dioxide-based positive electrode (2) ; and an asymmetric capacitor part is formed by the capacitor electrode (3) and one electrode selected from the lead based negative electrode (1) and the lead-dioxide based positive electrode (2); and wherein all negative electrodes are connected to a negative busbar (9), and all positive electrodes are connected to a positive busbar (8).
