The invention provides a manufacturing method for a self-charging energy unit and the self-charging energy unit. The manufacturing method comprises the steps of covering the upper and lower sides of a flexible diaphragm with two solid-state electrolyte layers respectively; enabling the flexible diaphragm covered with the two solid-state electrolyte layers on the two sides to be clamped between two flexible electrodes to obtain a solid-state flexible supercapacitor; forming PDMS thin films on the upper and lower sides of the drying supercapacitor respectively to be used as packaging layers; sputtering ITO electrodes on the flexible substrate to obtain four ITO electrodes; coating the surfaces of the second ITO electrode and the third ITO electrode with a PDMS solution, and drying to obtain two PDMS thin film layers; enabling a first positive polarity friction material and a friction material electrode layer, a second positive polarity friction material and a friction material electrode layer, a first friction material electrode, a second friction material electrode, a first negative polarity friction material layer and a second negative polarity friction material layer to be combined to obtain the friction generator; and enabling the upper and lower surfaces of the packaging layers to be adhered to the surfaces of the second flexible substrate and the third flexible substrate respectively to obtain the self-charging energy unit.
Description
technical field [0001] The invention relates to the field of micro-energy energy collection and energy storage, in particular to a self-charging energy unit based on the integration of a friction generator and a supercapacitor and a manufacturing method thereof. Background technique [0002] With the rapid development of the global economy and the increasing energy crisis, converting the mechanical energy in the environment into electrical energy and utilizing it is a research hotspot in the field of micro-energy. At present, there are mainly three types of energy harvesting methods for mechanical energy: piezoelectric, electromagnetic and electrostatic. However, most of the electromagnetic and piezoelectric energy harvesting methods need to rely on special functional materials, such as permanent magnets and various piezoelectric materials, etc., while electrostatic energy harvesters require external power supply or electret energy supply. To a certain extent, their wide ap...
