Scientists have taken an important step toward next-generation energy technology by developing a proof-of-concept quantum battery that can charge, store, and release energy. This early prototype represents the closest progress so far toward building a fully functional quantum battery.
Unlike traditional batteries, which rely on chemical reactions, quantum batteries rely on unusual principles of quantum physics. These exploit effects such as superposition and interactions between light and electrons, which could enable faster charging and greater energy storage capacity.
Although practical quantum batteries are not yet available, such advances suggest that they may eventually reshape the way energy is stored and delivered.
The research was led by Australia’s national science agency, CSIRO, in collaboration with RMIT University and the University of Melbourne. The findings were published in the journal March 13th. Light: Science and Applications.
Quantum batteries get faster as they grow
Study co-author and RMIT PhD candidate Daniel Tiben said the team had discovered a surprising benefit.
“Our research shows that the larger the quantum battery, the faster it charges, but this is not how batteries work today,” Tiben said.
“This is a sign that quantum batteries may someday surpass traditional energy storage technologies.”
This behavior is in clear contrast to traditional batteries, where efficiency does not increase as size increases. This discovery highlights a potential path to a more powerful and efficient energy system.
Working prototype demonstrates key functionality
Co-author Daniel Gomez, professor of chemical physics at RMIT, described the device as a major milestone.
“We demonstrated a device that can charge, store that energy, and then discharge it,” Gomez said.
“This is an exciting development in a rapidly growing interdisciplinary field.
“We hope that quantum batteries will soon become not just a theoretical idea, but something that can be built in the lab.”
Quantum batteries operate using core principles of quantum mechanics, such as superposition and entanglement, rather than the chemical processes used in today’s batteries.
The prototype itself is a small layered organic device. It can be charged wirelessly using lasers, demonstrating how energy can be delivered without a direct physical connection.
Laser charging and future energy possibilities
Lead author Dr James Quach, a CSIRO scientific leader, said the research points to a new kind of energy future.
“Our proof-of-concept device demonstrates rapid, scalable charging and energy storage at room temperature, laying the foundation for next-generation energy solutions,” he said.
“While there is still much work to be done in quantum battery research, we have taken an important step towards realizing the potential.
“My ultimate goal is a future where we can charge electric cars much faster than gasoline cars and wirelessly charge devices over long distances.”
Transition to real-world applications
The research team is currently working on extending the amount of time quantum batteries can hold a charge. Improving energy storage time is critical to making this technology practical and commercially viable.
Although still in their early stages, this breakthrough suggests that quantum batteries could one day enable faster charging, wireless energy transfer, and performance that exceeds today’s battery technology.
