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.
Stackelberg game framework optimizes distributed energy storage allocation
Researchers have developed a game-theory-based method for optimizing the location, capacity and operation of distributed energy storage. Simulations on a 33-node distribution network reportedly reduced load fluctuations from 25.98% to 14.25% while requiring around 85% less storage capacity than conventional methods.
New framework optimizes energy storage for worst-case grid outages
Researchers have developed a framework that simultaneously determines the optimal siting and sizing of energy storage while identifying worst-case grid component failures. They said the framework analyzed power networks with up to 116 buses in less than 100 seconds.

JT Solar teams with UNSW to launch battery testing lab
Researchers from the University of New South Wales and clean tech company JT Solar Technologies have established a facility to test the real-world performance of battery energy storage systems as Australia’s home battery installations numbers continue to climb.
AI framework identifies five novel oxide candidates for battery hosts
US researchers used generative artificial intelligence to screen thousands of candidate crystal structures for multivalent-ion battery electrodes, then built a separate AI system to propose lab synthesis routes for the untested materials.
