HiTHIUM Unveils Next-Gen Sodium-Ion Energy Storage Technology to Revolutionize the Market

HiTHIUM's Innovative Sodium-Ion Energy Storage Solution

On September 16, 2026, HiTHIUM, a renowned leader in energy storage technology, took a significant leap towards advancing sustainable energy solutions by introducing its next-generation integrated sodium-ion energy storage system during the event dubbed "Powered Day in, Day out". This landmark event marked the unveiling of the Power N4.0 MWh, a sodium-ion energy storage system boasting an impressive capacity of 4 MWh equipped with the high-capacity sodium-ion battery, Cell N785Ah. HiTHIUM has ambitious plans to scale production and commence deliveries in 2027, offering a long-lasting solution designed to operate for 30 years, thus positioning sodium-ion technology at the forefront of energy infrastructure deployment.

Leveraging fully integrated capabilities covering materials, cell design, manufacturing, system integration, and lifecycle services, HiTHIUM is meticulously transitioning sodium-ion technology from validation phases to large-scale deployment. Dr. Nazar Yi, HiTHIUM's Chief Technical Officer, emphasized the urgent need for energy storage technologies to overcome barriers of affordability and availability to enable widespread deployment. He pointed out that sodium, abundant and widely available, significantly enhances resource security and supply chain stability.

As advancements in sodium-ion battery materials, manufacturing processes, and supply chains continue to evolve, the landscape of these batteries is shifting from being merely energy technologies to becoming essential infrastructure. hiTHIUM has utilized its integrated capabilities in R&D, manufacturing, quality assurance, and supply chain development to drive the sodium-ion technology forward, carefully tracing its roots back to the 30-year history of lithium-ion batteries.

Dr. Aileen Wang, the Director of HiTHIUM's Battery Research Institute, expressed their commitment to integrated innovation in cell design and manufacturing processes. This led to the development of the Cell N785Ah battery aimed at energy storage, which offers an astounding lifespan of 20,000 cycles, supports storage durations from 2 to 8 hours, and is fully compatible with HiTHIUM's existing lithium-ion battery manufacturing platform.

The Power N4.0 MWh utilizes an innovative sodium-ion architecture that features a stacked cell design, a dedicated battery management system (BMS) capable of maintaining a state of charge (SOC) estimation accuracy of less than or equal to 2.5%, and compatibility with power conversion systems (PCS) ranging from 800 to 1,500 V. Additionally, the system's power utilization rate exceeds 20% compared to HiTHIUM's previous-generation sodium-ion systems, further enhancing its deployment efficiency.

Optimizing the system architecture allows for a reduction in station footprint by 30%, achieving an overall efficiency exceeding 88% over 24-hour cycles. The hybrid air-liquid cooling mode, AI-based thermal management, and integrated weather monitoring systems leverage weather data to select the most cost-effective cooling mode, minimizing auxiliary energy consumption in operation by 30% and standby energy usage by 50%.

HiTHIUM's integrated engineering capabilities and pre-modularized design for maintenance ease offer the Power N4.0 MWh a remarkable lifespan of 30 years. Dr. Wang acknowledged, "Thirty years signifies 10,950 days of validation—a long-term commitment to our clients, ensuring that electrochemical energy storage is evaluated and held to the same lifespan standards as traditional infrastructures."

As HiTHIUM's sodium-ion technology expands its applications from large-scale storage to commercial, industrial, and residential uses, it aims to create comprehensive solutions tailored to diverse scenarios, promoting broader access to energy. Additionally, HiTHIUM has initiated the "∞Edge Pioneer" program to test batteries and systems under extreme conditions, with plans to report progress over the next three years while gradually launching the "∞Power Next Technology Packages for Extreme Environments" aimed at reducing the average lifecycle cost of energy storage to approximately 0.1 RMB per kWh.
