Iron-mediated cathode enables 206 Wh/kg sodium-ion pouch cell
Chinese researchers have developed an iron-mediated strategy that improves the reversibility and stability of lattice-oxygen redox reactions in sodium-ion battery cathodes. A 15.8 Ah pouch cell using the cathode achieved an energy density of 206 Wh/kg, with lattice-oxygen redox reversibility reaching 99%.
New electrode design by German institutes increases battery energy density by up to 15%
Fraunhofer ISE and its partners have developed thicker electrodes that could increase battery cell energy density by 10% to 15% without adding weight. The PFAS-free, solvent-free concept has been demonstrated in lithium-ion, sodium-ion, and zinc-ion cells and is designed for cost-effective mass production.
UNSW launches grid protection project for grid-forming BESS and inverters
Researchers at the University of New South Wales have launched a three-and-a-half-year project to examine how inverter-based resources interact with grid protection systems. The AUD 12.9 million initiative will use modeling, simulation and hardware-in-the-loop testing to assess fault-current behavior and protection requirements.

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.
