▎ 摘　　要

NOVELTY - The device has a foam nickel electrode (3) connected with an outer layer of a high-strength insulating shell (1). A collector (4) is connected with the foam nickel electrode that is fixed with Nano-porous graphene particle. A counter electrode (5) is filled with blockage preventing ion solution (7). A detachable piston (6) and the high-strength insulating shell are fixed on a vibrating object. The foam nickel electrode absorbs the blockage preventing ion solution due to moving process of the detachable piston. The counter electrode is fixed with the Nano-porous graphene particle. USE - Device for converting waste vibrational energy into electrical energy by using double electric layer. ADVANTAGE - The device can realize waste vibrational energy converting into the electrical energy through the double electric layer so as to realize recycling and re-utilizing waste vibrational energy, monitor vibration frequency of a sensor, and has low converting cost, simple structure and convenient to large-scale production and application. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for converting waste vibrational energy into electrical energy by using double electric layer. DESCRIPTION OF DRAWING(S) - The drawing shows a partial sectional view of a device for converting waste vibrational energy into electrical energy by using double electric layer.
