Quantum batteries that charge wirelessly might never lose efficiency

Quantum batteries could be charged wirelessly and more effectively with the help of a hollow metal tube and an electromagnetic field.

Quantum batteries are a new and still largely theoretical form of energy storage device that can charge extraordinarily quickly thanks to quantum effects. While this property would make quantum batteries useful in the future for powering electric vehicles or smartphones, theory suggests that quantum batteries are susceptible to disturbances from their environment, which means they could spontaneously lose charge or undergo …
