HiTHIUM Unveils Cutting-Edge Sodium-Ion Energy Storage System to Revolutionize Energy Solutions

Revolutionizing Energy Storage with HiTHIUM's Sodium-Ion Solution

On September 16, 2026, HiTHIUM, a prominent player in the global energy storage sector, introduced a breakthrough sodium-ion energy storage system at their event titled 'Powered Day in, Day out.' This innovative system features the Power N4.0MWh, a robust 4MWh energy storage solution equipped with the high-capacity Cell N785Ah battery. Targeting commercial scale deployment, HiTHIUM plans to begin full production by 2027, marking a significant step forward in sodium-ion technology for industrial applications.

The new sodium-ion system is designed with a service life of up to 30 years, solidifying its potential for large-scale infrastructure deployment. Dr. Nazar Yi, Chief Technology Officer of HiTHIUM, emphasized the importance of making energy storage affordable and accessible. He noted that sodium, being a widely abundant resource, enhances supply chain stability while supporting long-term energy solutions.

HiTHIUM's approach combines extensive research across various domains such as materials science, cell manufacturing, and system applications. Dr. Aileen Wang, Director of the Battery Research Institute, explained how the company retraced the development path of lithium-ion batteries to enhance sodium-ion technology. The Cell N785Ah has a lifespan of 20,000 cycles and can operate with storage durations ranging between 2 to 8 hours. Notably, it is also compatible with HiTHIUM's existing lithium-ion production infrastructure, facilitating a swift transition towards sodium-ion production on a larger scale.

Key Features of the N4.0MWh System

The Power N4.0MWh boasts a unique sodium-ion architecture, characterized by its innovative stacked-cell design. Its battery management system (BMS) features a state-of-charge (SOC) estimation accuracy of 2.5% or less and supports voltage ranges from 800V to 1500V. Compared to previous generations, power utilization has improved by over 20%, which significantly reduces deployment barriers for customers.

Space efficiency is another highlight; the optimized system architecture reduces the physical footprint by 30%, achieving a comprehensive efficiency rate above 88% over 24 hours. This achievement is complemented by its hybrid air-liquid cooling method and AI-driven thermal management, which leverages weather data to optimize cooling strategies, thereby lowering auxiliary power consumption both during operation and in standby modes by 30% and 50%, respectively.

Dr. Wang highlighted the 30-year service life, illustrating HiTHIUM's commitment to reliability and confidence in their technology. He stated, "30 years means 10,950 days of validation—a long-term commitment to our customers." This durability positions electrochemical energy storage solutions on par with traditional infrastructure evaluation standards.

Expanding the utility of sodium-ion technology, HiTHIUM plans to roll out its innovations across various scales, from utility applications to commercial and residential energy needs. The company recently launched the Edge Pioneer Program to rigorously test batteries in extreme conditions, setting the stage for further advancements and the release of technology packages designed specifically for challenging environments.

In summary, HiTHIUM is poised to lead the charge in sodium-ion technology, with ambitions for a cost of electricity storage (LCOS) as low as RMB 0.1 per kWh. This forward-thinking initiative not only supports industrial progress but also contributes significantly to global efforts in sustainable energy solutions.
