A breakthrough straight out of the quantum frontier: scientists have created the first functional prototype of a quantum battery. Instead of chemical reactions, this device stores energy using light and quantum mechanics—operating even at room temperature.

Its most striking feature is superextensive charging, where the system charges faster as it grows, driven by collective quantum behavior. Still in early stages, this technology could redefine energy storage—powering everything from electric vehicles to renewable grids with unprecedented speed and efficiency.
