RECHARGEABLE BATTERY CELL HAVING INTEGRAL VIBRATING MEANS

摘要

A rechargeable battery cell (10) has an integral vibrating means. The cell has a positive electrode (14), a negative electrode (16), and an electrolyte (18) disposed between the two electrodes. The electrolyte contains a piezoelectric material (20) that vibrates when subjected to an alternating electric field. In one embodiment, at least one of the electrodes contains a piezoelectric material that functions as a vibrating means when subjected to an alternating electric field. In another embodiment, a piezoelectric material that functions as a vibrating means when subjected to an alternating electric field is attached as part of a current collector (22) to at least one of the electrodes. The piezoelectric material performs an additional function of being an electronic insulator for the purpose of stacking the cells.
