Abstract

The invention discloses an organic electrolyte-based micro super conductor and a manufacturing method thereof and belongs to the technical field of microelectronic machinery. In the micro super conductor, a microelectrode, a porous polymer isolator and a microelectrode are arranged on a polyimide support body in turn; electrolyte is soaked in the microelectrode and the isolator ; the same polyimide support body is covered on an assembly surface to form a capacitor unit; the polyimide support bodies of a plurality of capacitor units are connected with one another and wound to form a coin-shaped structure; both sides of the coin-shaped structure are provided with aluminum sealing covers which serve as electrode terminals for collecting fluid; and the aluminum sealing covers are contacted with the microelectrode in large areas, so that the resistance of the micro super conductor can be reduced effectively, and the energy storage characteristic of the micro super conductor is further improved. The working voltage of the micro super conductor is 2.5V, the volume is 0.2 farad, the internal resistance is only 15 ohms, the rated discharge current is up to 5 milliamperes, the size is only 50 mm<3>, and the high energy storage characteristic is achieved.

Description

technical field [0001] The invention belongs to the technical field of microelectronic machinery, in particular to a micro supercapacitor based on an organic electrolyte 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 e...
