Abstract

The invention provides a preparation method of an alumina-based water-voltage generator functional area. The preparation method comprises the following steps: placing ethyl cellulose, alumina nanoparticles and alumina nanofiber slurry into a fixed ceramic model, arranging and fixing folding electrodes at two ends, carrying out annealing in an air atmosphere, naturally cooling to room temperature,and coating the periphery of the functional area with a sealing layer to obtain the alumina-based water-voltage generator functional area. The energy density utilized by a water-voltage generator is far higher than that of a water-voltage battery, structural limitation is less, limitation of evaporation and capillary force is overcome, the charge collection efficiency can be greatly improved by the folding electrodes, and the mechanical performance of the water-voltage generator functional area is excellent due to a reinforced concrete structure of nanofibers and nanoparticles.

Description

technical field [0001] The invention relates to the field of preparation of hydroelectric generators, in particular to a method for preparing functional regions of alumina-based hydroelectric generators. Background technique [0002] The traditional water energy utilization model is greatly restricted by natural conditions and is easily affected by external factors such as terrain and climate. The construction and use of large-scale facilities and equipment may easily lead to ecological damage and cost increases. Nanomaterials have significant quantum effects and surface effects, and can be coupled with various forms of water to output significant electrical signals. For example, graphene can directly convert the energy of dragging and falling water droplets into electrical energy through the boundary motion of the electric double layer. , It can also convert seawater wave energy into electrical energy. Nanostructured materials such as carbon black can continuously generate...
