Revolutionizing Energy Storage: Hithium’s Groundbreaking kAh Battery Cell

On June 11, 2025, at the SNEC 2025 conference in Shanghai, Hithium, a global frontrunner in energy storage technologies, unveiled the Cell 1175Ah, the world's first mass-produced kAh battery cell. This significant development is a game changer in the realm of long-duration energy storage, enabling large scale deployment in various applications. The event was themed "Leading the Future, Forged for Safety," emphasizing Hithium’s commitment to safety and reliability in energy storage solutions.

Pioneering Innovations in Battery Technology

Hithium's journey toward this innovative battery cell began back in 2022 when the company identified the burgeoning demand for long-duration energy storage solutions. This foresight led to strategic investments in research and development as well as the establishment of a manufacturing base in Chongqing. Overcoming challenges related to size, process complexity, and quality control, Hithium has implemented five pivotal innovations in their manufacturing process:

1. Precision Coating Technology: The company achieved a remarkable coating mass density coefficient of variance (COV) of less than 0.2%. By utilizing high-precision CCD cameras for online inspection, they ensured stable and high-quality product consistency.
2. Efficiency in Electrode Stacking: A notable improvement in electrode stacking allowed for an astonishing accuracy of 0.5mm in alignment and a stacking throughput increase of 35% compared to traditional methods, with a rapid time of just 0.1625 seconds per sheet.
3. Unique Cell Structure: Hithium introduced an original "integrated 3D airflow top cover" design, enhancing structural stability and efficiency in larger-scale components. Specialized automation equipment furthered the manufacturing process, tackling industry bottlenecks effectively.
4. Enhanced Back-End Manufacturing: Innovations such as high-efficiency baking and high-pressure electrolyte filling have boosted back-end manufacturing efficiency by 45%, significantly streamlining production.
5. Advanced Cell Wrapping Methods: A new flexible lamination roller system mitigates common issues like wrinkling and bubbling, ensuring the integrity of packaging for ultra-large cells.

Commitment to Safety

With a focus on safety, Hithium has integrated a multi-layer safety architecture across the entire energy storage system lifecycle. Dr. Xiaoxiao Liu, Hithium's product safety expert, outlined their approach:

• - Cell Level: They enhanced safety by utilizing advanced electrolyte formulations that create high-temperature resistant layers, improving both longevity and safety.
• - Pack Level: Their dual-mode thermal protection structure effectively mitigates thermal propagation risks, ensuring greater safety in larger systems.
• - BMS Level: Integrating functional safety with cybersecurity, they employ multimodal early-warning systems alongside redundant control technologies to maintain operational stability.
• - System Level: The adoption of multi-layer fire-resistant and heat-insulating materials guarantees structural integrity while proactive thermal runaway prevention strategies are implemented.

Accelerating Global Expansion with Authoritative Certifications

During the event, Hithium proudly announced that the ∞Cell 1175Ah has secured UL 1973 and UL 9540A certifications, affirming its adherence to global safety standards. These accolades not only reinforce the cell's market readiness but also lay a solid foundation for Hithium's entry into the lucrative North American market.

In addition, Hithium revealed its strategic partnership with El Mor, a leading engineering, procurement, and construction (EPC) firm in Israel. This collaboration is set to launch Hithium's inaugural long-duration energy storage project in Romania, marking a pivotal step toward expanding the local energy storage market.

Conclusion

Hithium’s successful mass production of the world’s first kAh battery cell signifies a monumental leap forward in energy storage technology. As the demand for efficient long-duration energy solutions surges, Hithium is well-positioned to set new benchmarks in the industry. Continuing its leadership as a top-tier energy storage provider, Hithium is poised to redefine the energy storage landscape with innovation and commitment to excellence.
