(Phys.org) Scientists from the universities of Alberta and Toronto developed a blueprint for a new quantum battery that doesn’t leak charge.
“A quantum battery is a tiny, nano-size battery meant to be used for applications on the nano scale,” explained U of A chemist Gabriel Hanna, who was principal investigator on the study.
To realize their idea, the research team considered an open quantum network model with high structural symmetry as a platform for storing excitonic energy—energy harnessed when an electron absorbs a sufficiently energetic photon of light. Using this model, they showed it is possible to store energy without any loss, despite being open to an environment.
