'Defying logic': This quantum battery actually charges faster the bigger it gets

Researchers at CSIRO and RMIT University have developed a quantum battery that charges faster as it grows larger, unlike traditional batteries that slow down when scaled up. The device uses a microcavity structure that confines light with organic molecules, creating hybrid states called polaritons that enable collective quantum interactions to accelerate energy transfer beyond classical limits. Experimental measurements show charging occurs on femtosecond timescales with energy density increasing alongside battery size, though current energy storage remains too small for practical applications.
