Embodiment 1

[0017] 1) Clean and dry the glass slides and titanium sheets for later use. 2) Take pancakes (belonging to grain processing products), the main materials of which are flour, corn flour and millet flour, and mix them in a ratio of 1:1:1. 3) Take the spicy sauce, spread it evenly on the titanium sheet and grind it into a paste. 4) Fix the clean slides, electrodes, and diaphragms together with clamps in the order of slides, electrodes, diaphragms, electrodes, and slides. The clean slides make the whole device flat, and make the electrodes and The fixture is electrically isolated for ease of testing and packaging. Edible oil is added dropwise between the electrodes and the separator as a liquid electrolyte. 5) Use the battery charge and discharge test system to test the performance of the battery. The parameters are set to 50uA, 2V. After testing, it is found that the discharge time of the battery is 6.12 s, the capacitance is 0.1530mF, and the specific capacitance is 1.071 F / ...

Embodiment 2

[0019] 1) Clean the titanium slices and glass slides with detergent or detergent, and dry the cleaned titanium slices and glass slides for later use. 2) Take nori sheets. 3) Heat the flour at 320 degrees Celsius and carbonize it to make a paste, spread it evenly on the titanium sheet, and smear it into a paste. 4) Fix the clean slides, electrodes, and diaphragms together with clamps in the order of slides, electrodes, diaphragms, electrodes, and slides. Vinegar was added dropwise between the electrodes and the diaphragm as a liquid electrolyte. 5) Use the battery charge and discharge test system to test the performance of the battery. The parameters are set to 28uA, 0.9 V. After testing, it is found that the discharge time of the battery is 73.76 s, the capacitance is 2.230 mF, and the specific capacitance is 2.75mF / g.

Abstract

The present invention discloses a supercapacitor capable of eating and a preparation method thereof. The supercapacitor comprises an electrode active layer, a diaphragm and electrolyte which are all edible, the supercapacitor employs a metal clamp as an electrode conductive substrate, and the assembling is performed according to the sequence from the metal clamp, the electrode active layer, the diaphragm, the electrode active layer and the metal clamp. The active materials employ spicy sauce or flour. The metal clamp is taken as the electrode substrate, the active materials, the diaphragm and the electrolyte of the capacitor are formed by food, the source of the food materials is wide, the cost is low, and the prepared capacitor has high safety and is environmentally friendly and pollution-free.

Description

technical field [0001] The invention belongs to the technical field of battery manufacturing, and in particular relates to an edible supercapacitor and a preparation method thereof. Background technique [0002] At present, energy and environmental issues are becoming more and more prominent, and human beings attach great importance to the research of energy storage technology and resource recycling technology. As a new type of energy storage device, supercapacitor has a series of advantages such as high power density, fast charge and discharge speed, long cycle life, wide operating temperature range, safety and pollution-free, etc. It has broad application prospects and is currently a research hotspot in the field of energy storage in the world. [0003] Electrode material is one of the key factors affecting the main performance of supercapacitors. However, as far as the current research situation is concerned, there is no supercapacitor that can be digested as a whole. ...
