World's first quantum battery charges faster the bigger it gets

Quantum battery upends the rules of charging

Scientists at Australia's CSIRO have unveiled the world's first working quantum battery prototype. Unlike conventional batteries, it charges faster as it grows larger, thanks to a quantum effect called superabsorption. The battery uses an optical microcavity filled with organic dye molecules and a laser, and works at room temperature. While it currently stores only a tiny amount of energy for nanoseconds, researchers believe such batteries could one day power quantum computers or even electric vehicles, though skeptics question their real-world viability.
