NANTONG, China, July 27, 2026 /PRNewswire/ — Highstar unveiled its full-chain battery
cell solution for artificial intelligence data centers (AIDCs) at the 2026 GGII 
Energy Storage Industry Summit. The portfolio spans three critical power layers:
grey-space UPS and high-voltage direct current (HVDC) systems, white-space battery
backup units (BBUs), and grid-side energy storage.

**Targeted cells for grey-space and white-space challenges**

As AI workloads increase rack density and load volatility, data centers require 
faster response, dependable backup, controlled temperature rise and stronger lifecycle
performance. Highstar’s solution centers on two products for the layers closest 
to computing loads.

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.

**Completing the chain with grid-side storage**

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.

**From individual cells to application collaboration**

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.
