Highstar has unveiled a full-chain battery cell portfolio designed to support the growing power demands of artificial intelligence data centers (AIDCs) at the 2026 GGII Energy Storage Industry Summit. The portfolio covers three key power layers within data center infrastructure: grey-space uninterruptible power supply (UPS) and high-voltage direct current (HVDC) systems, white-space battery backup units (BBUs), and grid-side energy storage.
As AI workloads drive higher rack densities and greater fluctuations in power demand, data centers require battery solutions capable of delivering rapid response, reliable backup power, controlled temperature rise and improved lifecycle performance. Highstar’s portfolio includes two cell solutions focused on the grey-space and white-space layers located closest to computing loads, addressing the specific power and performance requirements of AI-driven data center operations.
For grey space, the 85Ah high-rate lithium iron phosphate cell is designed for UPS and HVDC systems that must deliver high power rapidly and sustain reliable backup under frequent pulse conditions. High-rate discharge, thermal control, safety and durability support compact system design while helping operators balance availability with lifecycle cost. In addition, the 50Ah sodium-ion battery cells are better suited for operation across a wide temperature range of -40°C to 80°C.
For white-space BBUs, Highstar offers a portfolio of tabless cylindrical cells spanning 18650 and 21700 formats, with both LFP and high-nickel NMC chemistries. Designed for BBU applications, these cells deliver high instantaneous power, low internal resistance, reduced temperature rise and enhanced safety, while accommodating different rack-space, power and cost requirements.
The grid-side system uses 314Ah lithium-ion cells and 160Ah sodium-ion cells, balancing long-duration energy storage, cycle life, and rapid power support. Together, the three layers create a coordinated portfolio extending from rack-level protection and system-level backup to upstream energy storage.
The portfolio combines lithium-ion and sodium-ion chemistries with prismatic and cylindrical platforms. Highstar’s technology integrates cathode, anode, electrolyte and separator development with structural approaches including tabless current collection, precision pressure relief and directional venting.
The full-chain architecture is designed to reduce selection and integration complexity for power equipment suppliers, system integrators and data center operators. It also provides a common foundation for joint validation and application-specific development across AIDC power architectures.
During the summit, Highstar also participated in the launch of the “2026 Global AIDC Power Supply Industry Development Blue Book” and was honored as a “Top Benchmark in AIDC Energy Storage,” earning authoritative recognition from the industry.
Looking ahead, the Highstar Battery Cell portfolio is expected to support the evolving power requirements of AI data centers, enabling greater reliability, efficiency and scalability as computing demand rises.
