HiTHIUM Unveils Next-Generation Integrated Sodium-Ion Energy Storage Solution for Large-Scale Deployment

HiTHIUM's Cutting-Edge Sodium-Ion Energy Storage Solution

On September 16, 2026, HiTHIUM, a global leader in energy storage technology, unveiled its innovative solution for sodium-ion energy storage at the event titled "Powered Day in, Day out". This launch marks a significant step towards advancing the industrialization of sodium-ion technologies. The centerpiece of this announcement is the ∞Power N4.0MWh, a 4 MWh sodium-ion energy storage system featuring the high-capacity battery, ∞Cell N785Ah.

The company plans to begin large-scale production and delivery by 2027, bringing a 30-year designed lifespan to the infrastructure-level deployment of sodium-ion technology. This ambitious initiative aims to drive the transition from validation-phase technologies to extensive applications.

Dr. Nazar Yi, HiTHIUM’s Chief Technology Officer, noted that for energy storage technologies to achieve substantial deployment, they must overcome two hurdles: affordability and availability. Sodium's abundance and wide distribution foster resource security and supply chain stability. As associated materials, manufacturing processes, and supply chains mature, sodium-ion batteries are poised to transition from niche technology to a fundamental infrastructure component.

HiTHIUM has leveraged its comprehensive expertise spanning research and development (R&D), manufacturing, quality control, and supply chain development to propel sodium-ion technology forward. \"Our journey from fundamentals in chemistry to 30 years of lithium-ion battery evolution has laid the groundwork for this leap,\" stated Dr. Aileen Wang, Director of the Battery Research Institute. With a focus on integrated innovation, HiTHIUM has developed the ∞Cell N785Ah, which promises a lifespan of 20,000 cycles and supports storage durations ranging from 2 to 8 hours. This battery seamlessly integrates with HiTHIUM’s existing lithium-ion battery manufacturing platform, expediting production scaling.

The architecture of the ∞Power N4.0MWh introduces stacked cell designs and an advanced battery management system (BMS) that maintains a state of charge (SOC) estimation precision of ≤2.5%. Its compatibility with power conversion systems (PCS) spanning 800 to 1500 V enhances energy output by over 20% compared to previous generation sodium-ion systems. This improvement significantly reduces implementation barriers.

Furthermore, the optimized system architecture decreases station footprint by 30% and guarantees over 88% overall efficiency around the clock. The unique hybrid air-liquid cooling method, AI-based thermal management, and integrated weather monitoring utilize climatic data to identify the most cost-effective cooling options, achieving a 30% reduction in operational auxiliary energy consumption and a 50% drop in standby energy use.

HiTHIUM's integrated engineering capabilities and modular design improve maintenance processes, contributing to the 30-year lifespan of the system. Dr. Wang emphasized, \"Thirty years translate into 10,950 days of validation—a long-term commitment to our customers.\" Such longevity allows for the performance of electrochemical energy storage solutions to be scrutinized, evaluated, and aligned with the life standards typical to infrastructures.

The deployment strategy for HiTHIUM’s sodium-ion technology extends beyond grid-scale storage, aiming to penetrate commercial, industrial, and residential sectors. The initiative also seeks to amplify energy accessibility, creating integrated systems tailored for diverse applications. As part of this vision, HiTHIUM announced the launch of the ∞Edge Pioneer program, which will conduct battery and system testing under extreme conditions over the next three years. Progressive releases of the ∞Power Next technology packages will follow, targeting a leveled cost of energy storage (LCOS) of 0.1 RMB per kWh.

The strategic strides made by HiTHIUM signal an era of affordable and accessible energy storage solutions poised to redefine how we utilize energy sustainably on a large scale. With a resolute focus on integrated sodium-ion technology, the imminent future under HiTHIUM’s innovation promises a green transformation in today's energy landscape.
