There’s silicon solid-state batteries for EVs, and soon, possibly even quantum battery technology. Researchers from Korea’s Basic Science and the University of Insubria in Italy have discovered a breakthrough in a quantum mechanical system called the micromaser. Put simply, it utilizes an electromagnetic field to store energy charged through a stream of qubits, while also simultaneously preventing overcharging.
Thanks to this breakthrough, micromaser is now believed to an excellent model of quantum battery after the researchers successfully demonstrated that this charging process is much faster than traditional charging. This means that you would be able to cut home charging times from 10-hours to 3-minutes, while supercharger stations could fully power an EV in a mere 90-seconds.

We show that a micromaser is an excellent model of quantum battery. A highly excited, pure, and effectively steady state of the cavity mode, charged by coherent qubits, can be achieved, also in the ultrastrong coupling regime of field-matter interaction,” said the researchers.
