Quantum batteries for super fast recharges

Quantum batteries could revolutionize the energy storage system


In the not too distant future the quantum batteries could revolutionize energy storage by means of a system that, to date, could appear paradoxical: decrease the charging time as the size of the battery increases, and consequently its capacity.

Until recently, this technology was only theoretical but there are many studies that go in this direction.


Technically, one would speak of quantum batteries, since these devices would operate on the basis of the principles of quantum physics, the science that studies the infinitely small.

A team of researchers has developed a prototype that demonstrates the possibility of manufacturing batteries with a charging power that progressively increases with the capacity of the battery itself. In practice, the recharging time is inversely proportional to the battery capacity, that is to the quantity of stored electrical charge.

The scholars in question are Tersilla Virgili, of the Institute of Photonics and Nanotechnologies of the National Research Council (Cnr-Ifn), Giulio Cerullo, of the Physics department of Politecnico di Milano and the researchers ofUniversity of Adelaide (University of Sheffield).

These have successfully demonstrated the concept of superabsorption in a device proof-of-concept.

How the scientists worked


The team placed an active layer of light-absorbing organic molecules – a dye known as Lumogen-F Orange – in a microcavity made with material consisting of organic molecules dispersed in an inert matrix, between two mirrors.
Then charging them through the use of a laser.

Dr James Q. Quach of the University of Adelaide explained that the active layer of the microcavity contains organic semiconductor materials capable of storing energy.
At the basis of the concept of quantum batteries, there is the idea that all molecules act collectively through the so-called quantum superposition. With the’increase the size of the microcavity and the number of molecules, it has been noted that the charging time has decreased. This represents a great discovery, which constitutes a kind of milestone in the development of the quantum battery.
