A group of scientists from the University of Washington in St. Louis learned how to use bricks as batteries to store electricity. The article was published in the journal Nature Communications.
This is made possible by a conductive polymer coating called PEDOT. This material is made up of nanofibers that work their way into the porous structure of the bricks, eventually turning it all into an “ion sponge” that conducts and stores energy.
For this, it is the red bricks that are needed, since the iron oxide contained in them is needed in order for the polymerization reaction to work.
In particular, these units become supercapacitors that can store more energy and charge and discharge faster than conventional batteries. They can be stacked together to resize the drive based on your needs. After installation, the entire wall is covered with a layer of epoxy so that only electricity can get inside, not dirt, dust, and water.
Modern supercapacitors charge much faster than batteries, but they also discharge much faster and can store only a small fraction of the energy, nevertheless, scientists from different countries are working to increase their energy intensity.
So, according to the authors of the study, in the future, whole houses can be built from bricks working on this principle, which will become supercapacitors for storing electricity.
