Biwatt releases sodium-ion storage system for C&I applications
Biwatt launched the modular PowerLake I3 sodium-ion storage system for C&I applications, offering 43.6 kWh–2.09 MWh configurations using NFPP cells. Available as indoor racks or IP55 outdoor cabinets, it delivers up to 65.5 kW per 130.8 kWh unit and is rated for 8,000 cycles.
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.
