Highstar's Comprehensive Battery Solutions for AI Data Centers

Overview

At the 2026 GGII Energy Storage Industry Summit, Highstar unveiled its innovative battery cell solutions tailored for Artificial Intelligence Data Centers (AIDCs). The company's comprehensive portfolio addresses various operational challenges faced by modern data centers, particularly regarding the increasing demands of AI workloads.

Key Products

Highstar's offerings are categorized into three essential performance layers:

• - Grey-Space Uninterruptible Power Supply (UPS) systems and High Voltage Direct Current (HVDC) solutions.
• - White-Space battery backup units (BBUs).
• - Grid-side energy storage systems.

These solutions were designed specifically to cater to the unique requirements of grey and white space environments, ensuring efficiency and reliability in performance.

Grey-Space Solutions

In the grey-space category, Highstar introduced a 85-Ah lithium iron phosphate cell characterized by its high discharge rate abilities. This enables it to provide rapid, reliable back-up power, essential for UPS and HVDC systems, particularly under impulse conditions. This cell balances high discharge rates, safety, thermal regulation, and longevity, allowing for compact system designs while managing lifecycle costs effectively.

Additionally, the company presented 50-Ah sodium-ion battery cells, which can operate effectively in a broad temperature range of
-40°C to 80°C, ensuring performance consistency regardless of environmental conditions.

White-Space Developments

For the white-space applications, Highstar has tailored a range of table-less cylindrical cells available in 18650 and 21700 formats. These cells leverage both LFP and high-nickel NMC chemistry, designed for BBU applications. These specialized cells exhibit high transient performance, low internal resistance, minimal temperature rise, and enhanced safety, allowing for various rack space and performance requirements.

Grid-Side Storage

Highstar's grid-side storage solution utilizes both 314 Ah lithium-ion cells and 160 Ah sodium-ion cells, ensuring a balance between long-term energy storage, cycle longevity, and prompt power support. This combination enhances overall system efficiency, providing a seamless flow of energy throughout the data center.

The complete range addresses critical protection from rack-level issues to broader system reliability and upstream energy storage needs, marrying lithium-ion and sodium-ion chemistries with cylindrical and prismatic platforms.

Streamlining Complexity

Highstar's end-to-end architecture is crafted to simplify the complexity involved in selecting and integrating components for power supply providers, system integrators, and data center operators. This provides a foundation for collaborative validation and tailored development across all power architecture of AIDCs, enabling efficient integration and application.

Recognition

During the summit, Highstar also contributed to the release of the Blue Book for the Development of the Global AIDC Power Supply Industry 2026 and received commendations as a “Top Benchmark in AIDC Energy Storage,” demonstrating its influential role in shaping industry standards.

Conclusion

Highstar's innovative battery cell solutions signal a significant leap forward for AI data centers, presenting options that not only enhance performance reliability but also ensure cost-effectiveness and adaptability for the future of computing needs. As data centers continue to evolve in response to capacity demands, Highstar remains at the forefront, leading the industry into an era of intelligent energy solutions that power the next generation of AI technology.
