Embodiment 1

[0072] The structure of the triboelectric nanogenerator provided by this embodiment is as follows: figure 1 shown. The triboelectric nanogenerator provided in this embodiment includes a fibrous capacitor, an interface control layer 4 and a friction electrode 5; the interface control layer 4 is coated on the fibrous capacitor, and the hollow tubular friction electrode 5 is set outside the interface control layer 4 The fibrous capacitor includes a fibrous positive electrode 1, a solid electrolyte 2 covering the fibrous positive electrode 1, and a negative electrode 3 covering the solid electrolyte 2. The distance between the positive electrode 1 and the negative electrode 3 of the fibrous capacitor is 20 μm. In addition, the fibrous positive electrode 1 has the same central axis as the negative electrode 3 as a whole. Generally speaking, the fibrous capacitor, the interface control layer 4 and the friction electrode 5 are all coaxial.

Abstract

The invention provides a friction nano-generator and a preparation method and application thereof. The friction nano-generator comprises a fibrous capacitor, an interface regulation and control layerand a friction electrode, the fibrous capacitor is coated with the interface regulation and control layer, and the friction electrode is tubular and sleeves the interface regulation and control layer;and the fibrous capacitor includes a fibrous positive electrode, a solid electrolyte covering the fibrous positive electrode, and a negative electrode covering the solid electrolyte. The preparationmethod comprises the following steps: 1) coating a fibrous positive electrode with a solid electrolyte, and arranging a negative electrode on the solid electrolyte to obtain a fibrous capacitor; and 2) arranging an interface regulation and control layer on the surface of the fibrous capacitor, and arranging a friction electrode outside the interface regulation and control layer to obtain the friction nano-generator. The friction nano-generator realizes simultaneous energy generation and storage, forms a self-charging energy storage system, and provides durable, maintenance-free and self-drivenenergy.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to a friction nanogenerator and its preparation method and application. Background technique [0002] With the development of society, the exploration and development of energy harvesting technology and new energy has become the frontier of research in the field of energy science, which is a major issue related to the international competitiveness and sustainable development of each country. Especially in the automotive industry, with the trend of energy saving and emission reduction and the environment of "Battle for Blue Sky", electric energy will gradually become a widely used energy source in automobiles. [0003] During the driving process of the car, its resistance forms include wind resistance, tire resistance, mechanical friction and so on. These energy characteristics are discontinuous, unstable, and wasted. If these energies can be utilized, it will be of great signific...
