Liquid-solid contact electrification friction nano-generator

Abstract

The invention discloses a liquid-solid contact electrification friction nano-generator, which comprises a high-molecular material layer, an electrode layer and a reference electrode, wherein the high-molecular material layer and the electrode layer constitute a power generation unit, and the power generation unit and the reference electrode respectively constitute two poles of the liquid-solid contact electrification friction nano-generator; both sides of the electrode layer are covered with the high-molecular material layer; the electrode layer is sealed in the high-molecular material layer on both sides; the electrode layer and the reference electrode constitute an electrode pair through a wire and electric equipment; and both the reference electrode and the power generation unit are partially placed in the liquid. The high-molecular material layer sufficiently wraps the electrode layer, thereby not only being capable of enlarging the liquid-solid contact area, but also being capableof shielding the inductive charge of the liquid around the electrode layer to the electrode layer, enabling the charge generated by the contact between the liquid and the material to be sufficientlytransferred, and forming current in an external circuit. Compared with the prior art, the generating capacity of the liquid-solid contact electrification friction nano-generator is improved by 8.3 times, thereby solving the technical requirement of long-term energy supply for ocean sensors.

Description

technical field [0001] The invention relates to the field of water energy collection and power generation, in particular to a liquid-solid contact electrification friction nanometer generator. Background technique [0002] Liquid fluctuations or flow energy are ubiquitous in the environment. At present, the main way to use liquid fluctuations or flow energy to generate electricity is to set flexible piezoelectric materials in the liquid or use gear-shaped electrode friction nanogenerators for water wave energy harvesting. The gear-shaping electrode type triboelectric nanogenerator has a small output power due to its small electrode area. The output current of the piezoelectric generator made of piezoelectric material is even smaller. [0003] For example, the Chinese patent CN201410140195.X discloses "triboelectric nanogenerator for harvesting liquid mechanical energy and power generation method", the triboelectric nanogenerator includes a power generation component prepare...

Problems solved by technology

Due to the small contact area of ​​the plug-type electrodes, the amount of charge transferred per unit area is low, so the power generation is limited, and the use of electrical devices is limited, and it is difficult to meet the real-time use of high-energy sensors or indicator lights. electricity demand
