Problems solved by technology

[0005] However, there are still many problems and disadvantages in the current humidity-based power generation device based on dynamic electron action. The carbon nanomaterials used (such as graphene oxide, carbon nanotubes, and carbon black) are finely prepared and the steps are complicated; the preparation cost is relatively high; the voltage and current are relatively low. Small; short stabilization time, etc.

Embodiment 1

[0029] Such as Figure 5 A kind of humidity micro-generation device based on dust-free paper and ink is shown, comprising: strip-shaped, length*width dimension is 6cm*1cm dust-free paper 1, the surface of dust-free paper 1 is covered with dry ink carbon; Both ends of the dust-free paper 1 with dry ink carbon are coated with conductive silver paint 2, which is used to connect the copper wire 4 as an electrode and the dust-free paper 1; any end of the dust-free paper 1 is also dried by dripping LiCl solution to form a LiCl crystal 3. Except for the part containing LiCl crystals exposed to the air, the other parts of the above-mentioned micro power generation device are packaged with adhesive tape.

[0030] Sampling ink carbon 2 carries out X-ray photoelectron energy spectrum analysis, the result is as follows figure 2 As shown, it is confirmed that the ink carbon contains more oxygen-containing functional groups.

Embodiment 2

[0032] A preparation method of a humidity micro-generation device based on dust-free paper and ink, comprising the following steps:

[0033] (1) Cut the dust-free paper into small pieces of 6cm*1cm; (2) Soak the cut dust-free paper in ink and let it dry in the air; (3) Drop 0.25ml LiCl solution (5M ) dried at 80°C to form crystals; (4) both ends of the paper were coated with conductive silver paint to isolate water and copper wires; (5) copper wires and paper were bonded with conductive silver paint, and the (6) Except for the part containing LiCl crystals exposed to the air, the rest of the device is sealed with adhesive tape.

[0034] The dust-free paper after sampling step (1) and the dust-free paper coated with ink in step (2) are respectively sampled for electron microscope scanning, and the results are as follows: figure 1 As shown in (a) and (b), it can be seen from the diagram that the surface of the dust-free paper has a unique porous structure, and the ink carbon is...

Embodiment 3

[0037] A preparation method of a humidity micro-generation device based on dust-free paper and ink, comprising the following steps:

[0038] (1) Cut the dust-free paper into small pieces of 6cm*1cm; (2) Soak the cut dust-free paper in ink and let it dry in the air; (3) Drop 0.25ml LiCl solution (2M ) dried at 80°C to form crystals; (4) both ends of the paper were coated with conductive silver paint to isolate water and copper wires; (5) copper wires and paper were bonded with conductive silver paint, and the (6) Except for the part containing LiCl crystals exposed to the air, the rest of the device is sealed with adhesive tape.

[0039] After the preparation was completed, the whole device was subjected to a performance test at a constant humidity of 50%, and a voltage of 0.26V and a current of 23.8μA were generated.

Abstract

The invention provides a humidity micro power generation device based on dust-free paper and ink and a preparation method and application thereof. The dust-free paper soaked in the ink and dried is placed in the air; moisture is absorbed from the environment by coating the dust-free paper with the LiCl solution, the moisture interacts with oxygen-containing functional groups in the ink to generatehydrated hydrogen ions, and the hydrated hydrogen ions are transmitted from one end to the other end along microporous channels in the paper to generate voltage and current, so that power is suppliedto electronic devices. The paper-based micro power generation device prepared can generate 0.35 V voltage under the environmental conditions of 50% relative humidity and 20 DEG C, can stably output the voltage for more than 100 hours, and has a remarkable effect.

Description

technical field [0001] The invention belongs to the field of micro-energy recycling, in particular to a humidity-based micro-energy generating device, a preparation method thereof, and a power generation method for micro-energy recycling using the device. Background technique [0002] Since the 21st century, energy and environmental issues have become bottlenecks restricting the progress of the world economy, society and human civilization. In order to solve the problems of depletion of traditional fossil fuels and environmental pollution, new energy and renewable energy technologies have become the orientation of technological development in the new era, such as solar energy, wind energy, water energy, nuclear energy, etc. have been successfully applied in life and production. However, there are many irregular and ubiquitous tiny energy sources in life, such as water molecules in the atmosphere, human body kinetic energy, mechanical vibration energy, etc., which are often i...
