Flexible super capacitor and preparing method thereof

Abstract

The invention discloses a flexible super capacitor and a preparing method thereof. The flexible super capacitor comprises electrolyte, a first electrode and a second electrode. The two electrodes are formed by flexible fibrous bases with the surfaces covered by semiconductor materials with pseudo capacitance. One end of the first electrode is of a spiral structure, the second electrode is of a linear structure, and the second electrode is arranged in the spiral structure of the first electrode. The electrolyte wraps the spiral structure of the first electrode and the part, located in the spiral structure of the first electrode, of the second electrode, and the two electrodes are fully combined. The flexible super capacitor effectively solves the problems that an existing capacitor is low in specific energy, in the conventional preparing technology, combination of the semiconductor material with pseudo capacitance and the flexible fibrous base is not firm, the semiconductor material and the flexible fibrous base grow in a disorderly mode, internal resistance is high, and an electronic transmission route is long, and the volumetric specific volume and volumetric specific energy of the capacitor are greatly improved.

Description

technical field

[0001] The invention belongs to the technical field of energy devices, and more specifically relates to a flexible supercapacitor and a preparation method thereof. Background technique

[0002] With the development of science and technology, thinning and flexibility are important development trends of portable electronic products. Foldable or bendable portable electronic products may greatly affect or even change human life style in the near future. Energy storage devices are the core components of portable electronic products. The development of high-performance flexible energy storage devices, such as flexible lithium-ion batteries and flexible supercapacitors, is one of the keys to the wide application of flexible electronic products. In August 2013, flexible technology has been selected by foreign media as one of the top ten technological advances in the world in 2013, and in October, LG announced that it has successfully mass-produced flexible display sc...
