Flexible supercapacitors are innovative high-performance energy storage devices that are widely used in flexible electronic devices and wearable technology. Compared with traditional batteries, flexible supercapacitors have many advantages, including fast charge and discharge, long cycle life, thinness and flexibility.
The working principle of flexible supercapacitors is based on electric double layer capacitance and pseudocapacitance effects. During charging, a double electric layer is formed between the positive and negative electrodes to store charge; during discharge, the charge is released from the electrodes and energy is output. This mechanism enables the storage and release of energy through ion migration and charge distribution.
The method of preparing flexible supercapacitors includes the following steps: First, select appropriate materials. Common materials include electrode materials with good conductivity and large surface area, such as carbon nanotubes, graphene, etc. Then the electrode is prepared, and methods such as chemical oxidation-reduction method and solution impregnation method can be used. The appropriate electrolyte is then designed to ensure capacitor performance. Finally, assembly is performed to assemble the electrodes and electrolytes together to form the final flexible supercapacitor.
Flexible supercapacitors have many advantages, such as fast charge and discharge speeds, long cycle life, thinness and flexibility, and high energy density. However, its energy density still needs to be improved, its preparation cost is high, its stability needs to be improved, and its capacity is relatively limited.
Flexible supercapacitors have broad application prospects in wearable devices, flexible electronics, smart homes and other fields. They can provide stable energy support for smart watches, smart clothing, biomedical sensors, etc., and can also be used as energy storage components in smart home devices, such as smart door locks and smart cameras.
