Problems solved by technology

Currently, the reported integrated systems are limited by single environmental energy utilization and complex device structures (Man Zhao et al. High-frequency supercapacitors based on carbonized melamine foam as energy storage devices for triboelectric nanogenerators[J], Nano Energy, 2019, 55: 447-453; Zifeng Conget al. Stretchable coplanar self-charging power textile with resist-dyeingtriboelectric nanogenerators and microsupercapacitors[J], ACS nano, 2020)
This not only increases the manufacturing process and cost of the device, but also inevitably causes energy loss

Abstract

The invention discloses a battery capable of collecting air energy and light energy, a preparation method and application thereof. The present invention firstly provides an integrated positive electrode module for a battery that can collect air energy and light energy. The polyaniline nanorod array is grown on the carbon fiber cloth in situ through chemical oxidation polymerization to obtain the carbon fiber cloth that supports the polyaniline nanorod array. After layering, it is assembled by laminating with waterproof breathable layer and air barrier layer. The integrated cathode module can realize multiple functions of energy storage and conversion, oxygen reduction catalytic activity, photothermal effect, waterproof and breathable, and controlled air entry. The integrated cathode module and metal zinc anode are assembled into a battery that can collect air energy and light energy, and three modes of work can be realized. By switching between different modes, the battery can overcome the low-capacity problem of traditional zinc-polyaniline batteries, and can also realize battery self-charging and multi-scenario applications in the presence or absence of air, which has broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of energy storage batteries. More specifically, it relates to a battery capable of collecting air energy and light energy and its preparation method and application. Background technique [0002] Due to the rapid development of modern electronic technology, there is a great demand for batteries with advantages such as excellent energy storage and conversion capabilities and high safety. Among various types of batteries, water-based rechargeable zinc-polyaniline (Zn-PANI) batteries have received extensive attention due to their large theoretical capacity, abundant and inexpensive raw materials, and environmental friendliness. In general, polyaniline exhibits low electrochemical activity under weakly acidic conditions (pH>4) due to the limited protonation process. In contrast, metallic zinc is easily corroded at pH<4. Therefore, the contradictory demands of anode and cathode on electrolyte pH limit th...
