A Strong Alliance Opens a New Chapter in Strategic Collaboration

Aiming at the profound transformation of the global energy structure, the demand for large-capacity energy storage in power systems is experiencing explosive growth. Energy storage batteries and systems featuring large capacity, high safety, high efficiency, and long cycle life have become essential for building a new-type power system and enhancing the power system's ability to absorb renewable energy.

This strategic cooperation represents a key initiative jointly undertaken by the two industry leaders based on their shared insight of future trends. The cooperation between the two parties goes beyond large-scale supply of energy storage products; it will also encompass comprehensive, multi-level collaboration across scenarios such as smart energy storage, C&I energy storage, shared energy storage, and distributed energy storage. Together, the two sides will explore high-safety, high-efficiency, and long cycle life energy storage solutions as well as innovative business models, working jointly to open new pathways for high-quality industrial development.

∞Cell 587Ah Empowers Customer Success with High-Quality Delivery

HiTHIUM’s ∞Cell 587Ah has secured a significant lead with its industry-first advantages of early release, early mass production, and early delivery.

The product was launched in 2024, achieved mass production in August 2025, and took the lead in large-scale implementation. Recently, it has successfully supported the batch delivery of CRRC Zhuzhou Institute's new generation of 6.25MWh BESS, which will be deployed in high-proportion renewable energy scenarios in northwest China, with a total scale exceeding the GWh level, validating the product's reliability and delivery capabilities through real large-scale projects. 

HiTHIUM’s ∞Cell 587Ah combines multi-dimensional advantages such as high performance, high safety, high reliability, long cycle life, and high adaptability, creating product competitiveness characterized by a shared technological origin, a unified platform, and overlapping advantages.

The ∞Cell 1175Ah  Advancing the 6.X Dual-Track

Serving as the cornerstone of this 120 GWh-scale cooperation, HiTHIUM's ∞Cell 1175Ah also represents a key highlight of the partnership.

In 2024, the ∞Cell 1175Ah and its supporting system were iteratively released, continuously pushing the technological boundaries of the industry. The ∞Cell 1175Ah product achieved mass production and rolled off the production line in June 2025, and completed the global delivery of the first batch of 6.25MWh 4h long-duration Energy Storage System in October this year, marking the product's official entry into the stage of large-scale application. 

This new cooperation agreement establishes a dual-track partnership for the 6.X ultra-high-capacity integrated systems, covering the entire journey from forward-looking planning to initial breakthrough, and from mass production to global delivery. Leveraging its comprehensive capabilities spanning R&D, manufacturing, and scenario verification, HiTHIUM is poised to continuously inject new momentum into the market.

Together, the ∞Cell 1175Ah and ∞Cell 587Ah create a versatile product matrix for multiple duration and scenario needs, enabling a large-capacity "dual-engine" system to provide customers with more flexible options and to empower their energy innovation.

Collaborating on an Industrial Ecosystem, Leading the Energy Future

This cooperation covers an end-to-end solution from energy storage battery cells, energy storage modules to system integration and even terminal scenario applications. The two parties will establish an in-depth collaboration mechanism, jointly expand the market, and continuously promote the implementation of large-capacity energy storage in more scenarios through technological innovation and large-scale application, providing strong support for the green, safe, and sustainable development of the global energy structure.

The collaboration between HiTHIUM and the CRRC Zhuzhou Institute not only marks a new starting point for the strategic win-win situation of both parties but also serves as an important symbol of promoting China's energy storage industry towards high-quality development. Starting from a cooperation on a scale of 120 GWh over five years, both parties will jointly commit to the popularization and application of large-capacity energy storage technologies, contribute to the construction of a new power system, and offer Chinese solutions for the global energy transition.
