A team of scientists from the universities of Alberta and Toronto have laid out the blueprints for a “quantum batteryö that nev
er loses its charge.
To be clear, this battery doesn’t exist yet — but if they figure out how to build it, it could be a revolutionary breakthrough
in energy storage.
“The batteries that we are more familiar with — like the lithium-ion battery that powers your smartphone — rely on classical el
ectrochemical principles, whereas quantum batteries rely solely on quantum mechanics,ö University of Alberta chemist Gabriel Ha
nna said in a statement.
A paper describing the research was published in the Journal of Physical Chemistry C. in July. The battery works by harnessing
the power of “excitonic energyö — the state in which an electron absorbs sufficiently charged photons of light.
The researchers found that their resulting battery model should be “highly robust to energy losses,ö thanks to the fact that th
eir battery is prepared inside a “dark stateö where it cannot exchange energy — by absorbing or releasing photons — with its su
rroundings.
By breaking down this “dark stateö quantum network, the researchers claim the battery could be able to discharge and release en
ergy in the process.
But the team has yet to come up with viable ways of doing so. They will also have to figure out a way to scale the technology f
or real-world applications as well.
