Scientists demonstrate quantum battery prototype with rapid charging
Scientists from Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO), RMIT University and the University of Melbourne have developed a quantum battery prototype that demonstrates rapid, scalable energy storage using collective quantum effects.
Small 24/7 clean power commitments could cut costs for long-duration storage
TU Berlin researchers say early demand for round-the-clock carbon-free electricity could help bring advanced energy technologies to market faster through technology learning effects. Grant funding for the research was provided by Google, which has since announced plans to build the world’s largest iron-air battery.
BESS in Brazil: Feasibility of three strategic approaches
Based on real data from the National Interconnected System between 2024 and 2025, the study evaluates the technical, economic, and regulatory performance of batteries operating as autonomous market agents, behind the meter for consumption shifting, or co-located with distributed solar generation.
Comparing safety profiles of lithium-ion, sodium-ion and solid-state batteries
New research finds that battery safety rankings are not universal but highly dependent on application scenarios, and shows that LFP batteries can emit high levels of hydrogen fluoride, challenging their reputation as the “safest” chemistry.

Compressed air energy storage enhanced by gravity
Scientists in China have simulated an advanced adiabatic compressed air energy storage, to which they added an elastic airbag with a heavy load situated above it. The energy, exergy, and economic analysis of the system showed that, due to the constant weight of the heavy load, the airbag’s pressure level remains unaltered during operation.
Researchers discover method to significantly extend quantum battery lifespan
Researchers discover method to significantly extend quantum battery lifespan
Researchers at the Royal Melbourne Institute of Technology (RMIT University) and Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) have developed a way to extend the lifetime of Dicke quantum batteries by up to 1,000 times, while maintaining their fast-charging properties enabled by superradiance.
