Highstar has launched a full-chain battery cell solution for artificial intelligence data centres (AIDCs), spanning grey-space UPS and high-voltage direct current (HVDC) systems, white-space battery backup units (BBUs), and grid-side energy storage. For grey-space applications, the company introduced 85Ah high-rate lithium iron phosphate (LFP) cells for UPS and HVDC systems, claiming rapid power output, reliable backup, thermal stability, and long service life. It also introduced 50Ah sodium-ion cells designed for extreme temperatures ranging from -40°C to 80°C. For white-space BBUs, Highstar offers tabless cylindrical cells in 18650 and 21700 formats using LFP and high-nickel NMC chemistries, engineered for high instantaneous power and low internal resistance, with improved thermal performance, enhanced safety, and flexible deployment. For grid-side systems, the company uses 314Ah lithium-ion and 160Ah sodium-ion cells to support long-duration energy storage, extended cycle life, and rapid power response. Highstar integrates cathode, anode, electrolyte, and separator development with structural approaches such as tabless current collection, precision pressure relief, and directional venting, combining lithium-ion and sodium-ion chemistries with prismatic and cylindrical platforms across the entire power chain from rack-level backup to grid-side storage.
