Sodium-Ion Gains Safety Validation, Illinois Boosts Grid Storage

  • U.S. startup Unigrid's sodium-ion batteries, using sodium chromium oxide (NCO) chemistry, passed Hyundai's rigorous safety tests, including extreme cold. This validation positions sodium-ion as a safer, viable alternative, supporting broader commercialization.

  • The Illinois Power Agency closed bidding for its first energy storage procurement, seeking 1 gigawatt of battery storage. This initiative under the Clean and Reliable Grid Affordability Act aims to meet demand and save Illinois $13.4 billion in energy costs over two decades.

  • Chinese automaker Geely announced its next-generation solid-state EV battery targets 500 Wh/kg energy density and a 1,000,000-kilometer lifespan. This intensifies global competition for high-performance solid-state solutions.

The Bottom Line

The battery sector is rapidly advancing, with sodium-ion proving safety and commercial viability, alongside significant grid-scale investment and aggressive solid-state developments.
