Description
Technical Field
The invention belongs to the technical field of energy storage batteries. And more particularly, to a battery capable of collecting air energy and light energy, a method of manufacturing the same, and applications thereof.
Background
Due to the rapid development of modern electronic technology, there is a great demand for batteries having advantages of excellent energy storage and conversion capability and high safety. Among various types of batteries, aqueous rechargeable zinc-polyaniline (Zn-PANI) batteries have received much attention due to their various advantages, such as large theoretical capacity, abundant and inexpensive raw materials, and environmental friendliness. Generally, polyaniline exhibits low electrochemical activity under weakly acidic conditions (pH > 4) due to limited protonation processes. In contrast, metallic zinc is susceptible to corrosion at pH < 4. Thus, this conflicting requirement of positive and negative electrodes for electrolyte pH limits the further development of high performance Zn-PANI cells.
To address this problem, two major strategies have been explored to enhance the electrochemical activity of PANI under high pH conditions. One is to introduce a specific functional group such as a sulfonic acid group, a carboxyl group or a hydroxyl group into the PANI molecular structure, and the other is to add a pH buffering substance to the electrolyte. Despite the advances made by these two strategies, the reported specific discharge capacity of Zn-PANI battery systems is still not high (Hua-Yu Shi et al A long-cycle-life self-treated polyamine catalyst for rechargeable batteries [ J ], Angewandte Chemie,2018,130(50): 16597-. Therefore, it remains a great challenge how to exploit the electrical activity of PANI under high pH conditions (i.e. pH > 4).
In general, rechargeable batteries (e.g., Zn-PANI batteries, etc.) cannot be discharged continuously without being charged by an external power source. In theory, constructing an integrated self-charging architecture can solve this problem. Such a system can collect external environmental energy such as solar, thermal, wind, mechanical, etc. using the environmental response module to compensate for the energy consumption of the energy storage module. It is noted that air, a ubiquitous substance in the environment, can also serve as a potential energy source. Furthermore, the introduction of environmental energy (e.g., solar energy, etc.) has been shown to be effective in enhancing the electrochemical performance of various cells such as zinc-air (Zn-air), lithium-air (Li-air), and lithium ion (Li-ion) cells. At present, the reported integrated system is limited by single environmental Energy utilization and complex device structure (Man Zhao et al. high-frequency supercompactor based on carbon scaled media foam as Energy storage devices for three dielectric nanogenerators [ J ], Nano Energy,2019,55: 447-. This not only increases the manufacturing flow and cost of the device, but also inevitably results in energy loss.
Therefore, in order to fully utilize the energy of the external environment, the application scenarios (such as no air) of the traditional Zn-PANI battery are expanded to meet various practical requirements, and the development of a system capable of collecting various environmental energies and the realization of high performance, multiple functionality and structural compactness of the device have important theoretical and practical research significance.
Disclosure of Invention
The invention aims to overcome the defects of the existing Zn-PANI battery and provides a battery capable of collecting air energy and light energy and a preparation method and application thereof.
The invention aims to provide an integrated positive electrode module for a battery, which can collect air energy and light energy.
The invention also aims to provide application of the integrated anode module in preparing intelligent devices capable of collecting environmental energy.
It is another object of the present invention to provide a battery that can collect both air energy and light energy.
The above purpose of the invention is realized by the following technical scheme:
the invention firstly provides an integrated anode module for a battery capable of collecting air energy and light energy, which is obtained by growing a polyaniline nanorod array on carbon fiber cloth in situ through chemical oxidative polymerization to obtain a carbon fiber cloth active layer loaded with the polyaniline nanorod array, and then laminating and assembling the carbon fiber cloth active layer, a waterproof breathable layer and an air blocking layer.
Preferably, the method for preparing the integrated positive electrode module comprises the following steps:
s1, carrying out ultrasonic treatment on carbon fiber cloth (CC) in hydrochloric acid, cleaning, and vertically fixing in a culture dish;

and S3, laminating and assembling the PANINA/CC active layer obtained in the step S2, a Waterproof Breathable Layer (WBL) and an Air Barrier Layer (ABL) to obtain the integrated positive module.
Preferably, the concentration of the aniline monomer in the step S2 is 0.1-0.6 mol/L. When the concentration of the aniline monomer is less than 0.1mol/L, the polyaniline nano-rod is thin and sparse, and the effective specific surface area is smaller; when the concentration of the aniline monomer is more than 0.6mol/L, the diameter of the polyaniline nano-rod is larger, and the effective specific surface area is smaller.
More preferably, the concentration of the aniline monomer in the step S2 is 0.4 mol/L.
Preferably, the time of the chemical oxidative polymerization reaction in the step S2 is 0.5-2 h. When the time of the chemical oxidation polymerization reaction is less than 0.5h, the polyaniline nano-rods are sparse, and the load capacity of the polyaniline does not reach the optimal state; when the time of the chemical oxidation polymerization reaction is more than 2 hours, the load capacity of the polyaniline nano-rods is too much, the nano-rods are too dense, and the polyaniline close to the surface of the carbon fiber can not fully contact the electrolyte, so that part of the polyaniline is not fully utilized, and the electrochemical performance is influenced.
More preferably, the time of the chemical oxidative polymerization reaction in the step S2 is 1 h.
Preferably, the temperature of the dark condition of step S2 is 4 ℃. The application of the integrated anode module in preparing an intelligent device capable of collecting environmental energy also falls within the protection scope of the invention.
Preferably, the smart device is a battery or a capacitor.
More preferably, the battery is a battery that can collect air energy and light energy.
The invention also provides a battery capable of collecting air energy and light energy, which is prepared from the integrated positive electrode module.
Preferably, the preparation method of the battery comprises the following steps: and assembling the integrated anode module and the metal zinc cathode in a two-electrode structure, and adding an electrolyte to obtain the metal zinc anode.
Preferably, the electrolyte is ZnCl2And NH4Mixed solution of Cl.
More preferably, the electrolyte is 2M ZnCl2And 3M NH4A mixed solution of Cl; the pH of the electrolyte is 5.

(2) The integrated anode module and the metal zinc cathode are assembled into the battery capable of collecting air energy and light energy. The battery can realize the working mechanism of three modes: the first is as a light assisted rechargeable Zn-PANI cell, the second is as a self-charging Zn-PANI cell with dual air and light assistance, and the third is as a light assisted primary Zn-air cell.
