Foreign media report (GLOBE NEWSWIRE, August 26): US sodium-ion battery company UNIGRID Inc. Announced that it has successfully completed Hyundai Motor Group's ZER01NE Accelerator program, achieving critical technology validation milestones for its proprietary sodium chromium oxide (NCO) chemistry. The collaboration, initiated in 2025, focused on identifying promising, non-flammable battery energy storage system (BESS) technologies; after an intensive evaluation process, UNIGRID's unique chemistry was selected for advanced testing.
Validation results showed that UNIGRID's NCO cells successfully passed stringent safety abuse tests with no fire and no thermal propagation; demonstrated superior durability in cycle life evaluations under full depth of discharge (100% DoD) with minimal capacity degradation under sustained continuous cycling; and validated robust operational capabilities across a broad thermal range from -20°C to 60°C. Jongguk Bae, Senior Manager at the Group's Green Factory Development Team, stated that UNIGRID's impressive validation performance demonstrates that its advanced sodium-ion chemistry is well positioned to meet the high safety and performance criteria of the Group's upcoming energy initiatives.
On the background: UNIGRID Inc., headquartered in San Diego, USA, is a sodium-ion battery company spun off from the University of California, San Diego, founded in 2021 by Darren H. S. Tan (CEO & Co-Founder) and Erik A. Wu, delivering safe, low-cost, advanced sodium-ion batteries for energy storage and electric mobility applications. Its NCO (sodium chromium oxide) technology route, together with NFPP (sodium iron phosphate pyrophosphate), is one of the mainstream routes for overseas sodium battery commercialization, with NCO known for higher energy density. For Hyundai Motor Group, this validation aligns with its 'Green Factory' initiative; moving forward, the Group alongside its Korean integration partners will jointly develop a sodium-ion NCO BESS system and use it as a core resource for distributed energy at its global production facilities and energy business, proving the system's excellence to the industry.
This stage is completed technology validation; cells have not yet entered mass production and delivery, and UNIGRID's NCO production line is still under construction (it previously disclosed a partnership with Syntropic Power to deploy 1 GWh of NCO capacity in North America); the BESS system development scale, deployment timetable and specific sites have not been disclosed; 'minimal capacity degradation' and 'stable operational capabilities' are qualitative statements in the press release without quantified cycle life figures.
