Abstract

The invention discloses a miniature super capacitor and a manufacturing method thereof, and belongs to the technical field of micro-electronic machines. The miniature super capacitor consists of a polyimide supporting body, microelectrodes, a gel-like electrolyte and a sliver seal cover, and has a winding structure, wherein each microelectrode comprises an energy storage material, a conducting material and an adhesive, and is prepared by a screen printing method; and the gel-like electrolyte is prepared by mixing polyvinyl alcohol, sodium carboxymethyl cellulose, potassium hydroxide and water, and is coated among the microelectrodes by a spin coating method. The manufacturing method can reduce the internal resistance of the miniature super capacitor and improve the energy storage property of the miniature super capacitor. The miniature super capacitor is widely used in fields of sensor network node power supplies, fuze power supplies and the like.

Description

technical field [0001] The invention belongs to the technical field of micro-electronic machinery, and in particular relates to a micro supercapacitor and a manufacturing method thereof. Background technique [0002] Miniaturization, miniaturization, and integration of electronic products are the general trend of technological development in the world today. Micro Electro Mechanical Systems (MEMS for short) has the characteristics of mobility, self-control, and integration, and is one of the most important technological innovations in recent years. When a subsystem can be integrated on a chip, the power supply must also complete the revolution of miniaturization and miniaturization. MEMS micro energy system refers to the integration of one or more power supply devices into a micro system with a characteristic size of micron level and a centimeter level based on MEMS technology, which can realize long-term, high-efficiency, multi-mode power supply, and is especially suitable...
