The MIT research team succeeded in creating a super capacitor that stores electricity using cement, carbon, black, and water.
If you use this as a tool when building a house, you can use the house like a battery.
It is also said that if you use this when paving roads with concrete, you can charge electric vehicles non-contactly.
The structure itself is like a capacitor. It consists of a membrane placed in an electrolyte and two conductive plates, and is charged/discharged using the movement of + and – ions. And the charge/discharge speed is faster than that of a battery.
The amount of power stored in the capacitor is determined by the surface charge of the conductive plate. The cement-based material used here is highly conductive carbon black mixed with cement powder and water into the concrete mixture, creating a naturally divided carbon structure within the structure, increasing the surface area. It is said to increase.
Then, by immersing this material in a standard electrolyte material such as potassium chloride, charging the carbon structure with charged particles, and separating the two electrodes made of this material by a thin space or insulating layer, a very powerful supercapacitor can be created. The amount of carbon required here is about 3% of the volume, and carbon black can be made inexpensively.
Here, it was determined that a 45 cubic meter concrete block can store 10 kWh, which is the amount of electricity used per day by an average household. So, if you mix this when building a house, you can store and use the electricity generated by solar panels.
Conversely, we created a small supercapacitor with a diameter of 10 mm and a thickness of 1 mm. I charged it to 1V and connected 3 of them to turn on the 3V light emitting diode. In the future, they plan to demonstrate it by making it the size of a car battery and up to 45 cubic meters, and they are also planning to put it on the road to charge cars.
