Hithium Energy Storage Releases New-Generation Sodium-Ion Energy Storage Integrated Solution

en.Wedoany.com Reported - On September 16, at its "Witnessed by Day and Night" online new product launch event, Hithium Energy Storage officially released its new-generation sodium-ion integrated solution dedicated to energy storage, unveiling the 4MWh sodium-ion energy storage system equipped with the ∞Cell N785Ah large-capacity sodium-ion battery — the ∞Power N4.0MWh — and announced that full-chain mass production and delivery will begin in 2027. Notably, the system features a 30-year design service life, offering a new answer for the large-scale application of sodium-ion energy storage with an energy-infrastructure-grade long lifespan.

As a leading global player in the energy storage industry, Hithium Energy Storage ranked TOP2 worldwide in energy storage battery shipments in the first half of 2026. Building on its accumulated technology, manufacturing, and industrialization experience in the lithium battery sector, Hithium Energy Storage has further expanded into the sodium-ion sector. Leveraging integrated capabilities spanning materials, cells, manufacturing, system integration, station applications, and full-lifecycle services, Hithium Energy Storage is further advancing sodium-ion technology from technical validation to large-scale application, accelerating the industrialization of sodium-ion technology.

Strategic Dialogue Opens the Event, Decoding the Logic of Sodium-Ion Industrialization

At the launch event, Dr. Yi Ziqi, Director and Chief Technology Officer of Hithium Energy Storage, held an in-depth dialogue with Xie Rongbin, Party Secretary, Chairman, and Editor-in-Chief of China Energy Automotive Communication Group Co., Ltd., and Editor-in-Chief of China Energy News, decoding the strategic logic behind Hithium Energy Storage's sodium-ion layout from dimensions including industry trends, resource endowment, and technological evolution.

Dr. Yi Ziqi stated that for energy storage technology to truly achieve large-scale application, it must cross two thresholds: first, affordability — the price must be sufficiently accessible; second, availability — resources must be obtainable over the long term and in a stable manner. Sodium resources are abundant and widely distributed, offering new possibilities for the energy storage industry to enhance resource security and supply chain stability. Hithium Energy Storage's cost target for its new-generation sodium-ion energy storage system is to at least match that of lithium batteries at a lithium carbonate price of 150,000 yuan/ton. As the sodium-ion material system, manufacturing processes, and industrial chain gradually mature, sodium-ion technology will further evolve from an energy technology into infrastructure. At the same time, greater resource availability and supply chain stability also enhance the long-term investment value of energy storage as a heavy asset.

Industrialization means not only achieving mass production of a single product, but also forming complete integrated industrial capabilities from materials and manufacturing to systems and applications. Building on its integrated capabilities in R&D, manufacturing, quality, and the industrial chain accumulated in the lithium battery sector, Hithium Energy Storage has further transferred its mature experience to sodium-ion technology, conducting integrated R&D and engineering practice from underlying materials to terminal stations, building a complete capability foundation for the large-scale deployment of sodium-ion technology.

Integrated Innovation from Materials to Manufacturing Processes, Creating the ∞Cell N785Ah New-Generation Large-Capacity Sodium-Ion Battery

The industrialization of sodium-ion technology must first address the cell.

"Starting from the most fundamental chemical materials, we are retracing the 30-year path that the lithium battery industry has walked," said Dr. Wang Shiwen, President of the Hithium Energy Storage Battery Research Institute, at the launch event.

Based on this approach, Hithium Energy Storage started from underlying material systems including cathode and anode materials and electrolytes, collaboratively advancing integrated innovation in cell design and manufacturing processes to create the energy-storage-dedicated ∞Cell N785Ah large-capacity sodium-ion battery.

On the cathode side, NFPP material with a phase purity of up to 97% was jointly developed with partners; on the anode side, hard carbon material was self-developed, achieving both low expansion and high rate capability through technologies such as pore structure regulation and surface defect repair, significantly improving the battery's calendar life. Meanwhile, the electrolyte specially adopts a "micro-bonding + targeted repair" formula to enhance film-forming stability and suppress consumption.

In terms of cell manufacturing processes, three major breakthroughs were achieved: ultra-thick coated electrodes compensate for the shortcoming in energy density; long-life structural component design for explosion-proof valves and weld seams that have passed over 20,000 breathing tests solves the fatigue problem caused by accumulated small deformations under massive cycling; and the wide-format large stacking technology from the advanced manufacturing system of lithium battery production lines is adopted to break through the bottleneck of large-scale sodium-ion mass production.

Based on collaborative innovation in material systems and cell manufacturing processes, the ∞Cell N785Ah sodium-ion battery features a native long cycle life of 20,000 cycles and supports 2 to 8-hour duration operation, covering the most mainstream duration scenarios in current power energy storage. At the same time, the product is fully compatible with the cell production lines and integration production lines of Hithium Energy Storage's kiloampere-hour lithium battery universal manufacturing platform, providing support for the rapid introduction of sodium-ion technology into mature manufacturing systems and the achievement of large-scale mass production.

Battery-Station Co-Lifespan: 30-Year Station Service Life, Sodium-Ion Energy Storage Moves Toward New Energy Infrastructure

As a new-generation sodium-ion energy storage solution, the ∞Power N4.0MWh possesses integrated advantages from material systems to cell manufacturing, and from system integration to stations. In addition to being equipped with the ∞Cell N785Ah, it also adopts a self-developed sodium-ion-dedicated battery management system (BMS), with whole-process state of charge (SOC) estimation accuracy of ≤2.5%. The sodium-ion-dedicated architecture is compatible with 800V to 1500V power conversion systems (PCS), allowing the existing ecosystem to be directly leveraged. The PCS rated power utilization rate is increased by more than 20% compared to the previous generation sodium-ion system, lowering the ecosystem threshold for sodium-ion technology to enter large-scale application.

In terms of system efficiency and operations and maintenance, the ∞Power N4.0MWh reduces station footprint by 30% through system architecture optimization, achieving an all-weather comprehensive energy efficiency of over 88%. At the same time, it adopts a proprietary air-liquid hybrid cooling mode and AI intelligent thermal management system, and has a built-in meteorological monitoring and early warning system, which can intelligently select more economical cooling modes based on real-time meteorological data, reducing operational auxiliary losses by 30% and standby auxiliary losses by 50%.

What truly determines the long-term value of the system is the reliability design that runs through the entire product lifecycle.

Hithium Energy Storage will leverage its integrated engineering capabilities from materials and cell manufacturing to systems and operations and maintenance, and relying on a pre-modular minimalist O&M design, the ∞Power N4.0MWh achieves an ultra-long service life of 30 years, matching the lifespan of traditional power equipment.

"30 years — after 10,950 days and nights of joint verification — is a long-term commitment we hope to deliver to our customers," said Dr. Wang Shiwen. "This means that for the first time, electrochemical energy storage can truly be viewed from an infrastructure perspective, accounted for using infrastructure cost logic, and held to infrastructure standards for its service life."

At the same time, Hithium Energy Storage's new-generation sodium-ion energy storage integrated solution will begin full-chain mass production and delivery in 2027. Starting from large-scale power energy storage, Hithium Energy Storage's new-generation sodium-ion technology will also extend to commercial and industrial applications, enter households, and reach inclusive energy access, serving different application scenarios with different technologies and different products, continuously building full-scenario integrated energy storage solutions.

Moving toward the light, witnessed by day and night. At the launch event, Hithium Energy Storage also announced the launch of the "∞Edge" Pioneer Initiative. Over the next three years, it will test Hithium Energy Storage batteries and systems of different technologies and different forms in various extreme environments and continuously disclose progress, while gradually releasing multiple ∞Power Next extreme scenario technology packages, continuously promoting electrochemical energy storage to truly become more inclusive and more reliable energy infrastructure, and ushering the full-lifecycle levelized cost of storage (LCOS) into the era of "one dime per kilowatt-hour."
