The researchers used red brick as a substrate for capacitors based on the conductive polymer polyethylene dioxythiophene (PEDOT). The energy in the polymer arises from Faraday reactions through oxidation, for which iron compounds can be used.
There are many such compounds in red brick. Chemists have developed a technology for applying polymer to brick blocks, which have proven to be good capacitors.
According to N + 1, the gel electrolyte capacitor showed a capacity of 1.38 farads per cubic centimeter, with 90% of the capacity remaining after ten thousand recharge cycles.
It is important that the basic properties of the brick are preserved, which means that it can be used simultaneously as a base for walls and as a capacitor. According to the authors’ calculations, such a wall can have a capacity of 11,500 farads per square meter of surface.
We will remind, earlier we told, than, according to the psychiatrist, the cry is useful.
