Hithium pushes into long-duration storage and AI data centres with 1,300Ah cell, 6.9 MW/55.2 MWh system, and lithium-sodium hybrid

Chinese battery manufacturer Hithium Energy Storage has announced significant advancements in energy storage technology, unveiling a new 1,300Ah battery cell alongside integrated long-duration energy storage systems (LDES).

These developments were presented at Hithium's annual Ecosystem Day on December 12, 2025.

The company is strategically moving beyond the conventional four-hour battery storage model, aiming to provide solutions that support grid stability and meet the demanding energy requirements of AI data centers.

The newly introduced 1,300Ah cell is a high-capacity lithium-ion battery designed to deliver enhanced performance and longer discharge durations.

Complementing this, Hithium revealed a large-scale integrated system capable of delivering 6.9 MW of power with a total energy capacity of 55.2 MWh, reflecting a focus on long-duration applications that extend well beyond typical short-term storage.

In addition to lithium-ion technology, Hithium is pioneering a lithium-sodium hybrid LDES solution, which offers promising cost and resource advantages for energy storage over extended periods.

This hybrid approach is particularly relevant for AI data centers, which require consistent, high-density energy storage to support intensive computational workloads.

By advancing both cell technology and system integration, Hithium is positioning itself as a key player in the evolving energy storage market, addressing the growing need for durable, scalable, and efficient storage solutions.

These innovations have the potential to enhance grid reliability, facilitate renewable energy integration, and support the expanding infrastructure of AI-driven industries.

The company's focus on long-duration storage aligns with global trends toward decarbonization and energy resilience, highlighting the critical role of advanced battery technologies in future energy systems.
