Proof of concept verifies physics that could enable quantum batteries
Quantum batteries could one day revolutionize energy storage through what seems like a paradox – the bigger the battery, the faster it charges. For the first time, a team of scientists has now demonstrated the quantum mechanical principle of superabsorption that underpins quantum batteries in a proof-of-concept device…..
Superabsorption had yet to be demonstrated on a scale large enough to build quantum batteries, but the new study has now managed just that. To build their test device, the researchers placed an active layer of light-absorbing molecules – a dye known as Lumogen-F Orange – in a microcavity between two mirrors…..
The team then used ultrafast transient-absorption spectroscopy to measure how the dye molecules were storing the energy and how fast the whole device was charging. And sure enough, as the size of the microcavity and the number of molecules increased, the charging time decreased, demonstrating superabsorption at work.
