Read original articleResearchers at RMIT University and CSIRO in Australia have developed a new quantum battery prototype that extends the energy storage lifetime by 1,000 times compared to previous models, improving from nanoseconds to microseconds. Although still experimental and not yet practical for real-world applications, this advancement marks a significant step forward in quantum battery technology. The team achieved this improvement by aligning two energy levels perfectly within the device, enabling more efficient energy storage.
Quantum batteries operate on quantum mechanics principles, storing energy by moving electrons into higher energy states using photons as charge carriers, rather than relying on ion flow like conventional batteries. They leverage quantum phenomena such as entanglement and superabsorption to enhance charging rates and energy density. Despite being a relatively new concept with practical devices lasting only nanoseconds until now, this breakthrough lays the groundwork for future research aimed at developing scalable, efficient quantum batteries. Potential applications include improving solar cell efficiency and powering small electronic devices, as noted by the researchers. The findings were published in the journal
