Description

Technical Field

[0001] The present invention relates to the technical field of water energy collection of hydrovoltaic generators, and in particular to a power generation system capable of utilizing bimodal water. Background Art

[0002] Faced with environmental pollution and energy crisis caused by fossil fuels as energy supply, the development of new green energy is one of the core trends of global technological innovation.

[0003] At present, researchers have developed a variety of new energy conversion devices, such as wind power generation, solar cells, moisture generators and friction nanogenerators, which can effectively convert energy in the environment into electrical energy. However, most of these new energy conversion technologies are limited by the environment. For example, they must have sunlight to generate energy, or they rely on high humidity in the environment, which will seriously limit their application scenarios. If the energy conversion method can be expanded, such as moisture power generation, which can generate electricity by absorbing moisture or by evaporating moisture, high-efficiency energy conversion can be achieved in all weather conditions and in various humidity environments. In addition, no pollutants are generated during the power generation process. Although some reports have tried to integrate a moisture absorption layer and an evaporation layer or adopt a strategy of first absorbing moisture and then evaporating to improve the moisture power generation capacity, the evaporation and moisture absorption processes restrict each other, and the performance is difficult to meet the needs of actual applications.

[0004] Therefore, designing a generator that can integrate evaporation power generation and moisture absorption power generation will further promote the application of moisture generators. Summary of the Invention

[0005] In order to solve the technical problems mentioned in the above background technology, a power generation system that can utilize bimodal water is provided.

[0006] The technical means adopted in the present invention are as follows:

[0007] A power generation system that can utilize bimodal water, utilizing the two forms of water for energy conversion, and realizing efficient conversion of water energy into electrical energy, comprises: power generation materials and electrodes; the electrodes are silver electrodes and conductive carbon ribbons;

[0008] The silver electrode is used to absorb and volatilize moisture; the conductive carbon tape is tightly attached to the power generation material to ensure that the power generation material is sealed.

[0009] Furthermore, a plurality of the electrodes are connected in series or in parallel to achieve large-scale power supply.

[0010] Furthermore, the power generation material can adapt to the external environment and can self-repair and generate electricity in a cycle for a long time.

[0011] Furthermore, the power generation material includes cellulose nanocrystals, polyvinyl alcohol and glycerol.

[0012] Furthermore, the method for preparing the power generation material comprises the following steps:

[0013] Step 1: Prepare cellulose nanocrystal solution by hydrolyzing cotton with sulfuric acid;

[0014] Step 2: uniformly mixing the cellulose nanocrystal solution, the polyvinyl alcohol solution, and the glycerol in a ratio of 2:1:2 to 2:1:3 to obtain a mixed solution;

[0015] Step 3: Place the mixed solution in a drying cabinet and set the temperature to 25° C. and the humidity to RH=35% to allow the mixed solution to reach a steady state of water content.

[0016] Furthermore, the solvent concentration of the cellulose nanocrystal solution is concentrated to 8 wt %.
