Researchers have developed a proof-of-concept quantum battery capable of charging, storing, and releasing energy, marking a step toward next-generation energy storage systems.
The study was led by CSIRO in collaboration with RMIT University and the University of Melbourne. The findings were published on March 13 in Light: Science & Applications.
Unlike conventional batteries that rely on chemical reactions, quantum batteries use principles of quantum physics such as superposition and interactions between light and electrons.
These properties could enable faster charging and higher energy storage capacity compared to existing battery technologies. While practical quantum batteries are not yet available, current progress suggests potential for future applications.
The research identified a key advantage in how quantum batteries behave as they scale.
Study co-author and RMIT PhD candidate Daniel Tibben said the team observed that charging speeds increased as the system grew larger.
“Our study found quantum batteries charge faster as they get larger, which is not how today’s batteries work,” Tibben said.
He added that this behavior could allow quantum batteries to outperform conventional energy storage technologies.
The team successfully built a working prototype that can charge, store energy, and discharge it.
Co-author Daniel Gómez described the development as a significant step in the field.
“We demonstrated a device that can be charged, store that energy, and then discharge it,” Gómez said.
The prototype is a small layered organic device that can be charged wirelessly using a laser, demonstrating a method for energy transfer without direct physical connections.
Lead author James Quach said the work points toward new possibilities in energy systems.
“Our proof-of-concept device showcases rapid, scalable charging and energy storage at room temperature, laying the groundwork for next-gen energy solutions,” Quach said.
He added that future developments could enable faster charging for electric vehicles and wireless energy transfer over long distances.
Researchers are now focusing on improving how long quantum batteries can retain their charge, which is a key factor for real-world applications.
Although still at an early stage, the findings suggest that quantum batteries could eventually offer faster charging, wireless energy delivery, and improved performance compared to current technologies.
