Explore our tier-1 engineered Sodium-ion (Na-ion) battery solutions optimized for residential solar, off-grid systems, telecom base stations, and industrial microgrids. Built with integrated intelligent BMS and extended cycle performance.
As global commercial and industrial sectors accelerate their transition toward decarbonization, energy storage system (ESS) integrators face compounding supply chain vulnerabilities, raw material price swings, and strict operating temperature constraints associated with traditional Lithium-ion (LFP/NMC) chemistries. Sodium-ion battery technology has emerged as a disruptive, highly resilient alternative engineered to solve these structural bottlenecks.
Sodium-ion energy storage cells function via a reversible intercalation mechanism similar to lithium-ion systems, where sodium ions ($Na^+$) shuttle between the cathode host structure and a hard carbon (HC) anode during charge and discharge cycles. However, due to the larger ionic radius of $Na^+$ (1.02 Å vs. 0.76 Å for $Li^+$), specialized cathode crystallographic matrixes are utilized:
Formulated as $Na_xMO_2$ (where M = Fe, Mn, Ni), layered oxides offer high volumetric energy density (140–160 Wh/kg) and rapid rate capability, making them ideal for residential split and stackable ESS systems.
Characterized by a open 3D framework structure ($Na_{2-x}Fe[Fe(CN)_6]$), PBAs deliver fast ion diffusion paths, long lifecycle durability, and exceptionally low cost for stationary industrial energy banks.
Sodium vanadium/iron fluorophosphates deliver superior thermal stability up to 500°C decomposition thresholds, offering over 6000–8000 deep cycles for heavy-duty commercial ESS installations.
When evaluating long-term Total Cost of Ownership (TCO) for global energy storage procurement, OEM/ODM buyers must assess operational thermal limits, logistics safety, cycle life degradation, and discharge rates.

The global energy storage procurement landscape is experiencing a fundamental structural shift. B2B enterprise buyers, EPC contractors, and OEM brands are rapidly incorporating Sodium-ion battery packs into their product portfolios due to five critical industry vectors:
Conventional LFP battery packs lose up to 50% of their effective capacity at sub-zero temperatures (-20°C) and require energy-intensive internal heating pads. Na-ion batteries retain over 85% of rated capacity at -30°C and operate reliably down to -45°C without active heaters, making them the default choice for Alpine, Nordic, and North American installations.
Lithium-ion batteries present severe hazard risks during sea and air transport, demanding strict SOC limits (typically under 30%). Sodium-ion batteries can be fully discharged to 0 Volts without inducing copper dissolution or internal shorts. This allows 0V safe shipping under standard UN38.3 protocols, significantly lowering insurance premiums and ocean freight costs.
By using aluminum current collectors for both anode and cathode (whereas Lithium requires expensive copper foils on the anode), Sodium-ion manufacturing drastically reduces raw metal requirements. As gigafactories scale globally, Na-ion cell costs are projected to drop 25–30% below LFP, securing long-term margin stability for B2B exporters.

Every single OEM batch undergoes rigorous automated end-of-line (EOL) testing, short-circuit validation, thermal shock chamber cycling, and vibration stress testing. Fully certified to UN38.3, IEC 62619, CE, and RoHS standards.
Direct insights from our senior battery engineering team answering key questions from global buyers and distributors.
Yes. Our OEM Sodium-ion battery packs are engineered with customized BMS voltage profiles (nominal 48V / 51.2V systems) that seamlessly communicate with standard hybrid inverters via CANbus or RS485 protocols, matching standard charge/discharge parameters.
Our industrial-grade Na-ion cells deliver 6000 to 8000+ deep discharge cycles at 80% Depth of Discharge (DOD) under 25°C. Even under extreme temperature stress (-20°C), cycle retention remains significantly higher than standard LFP chemistry.
Unlike Lithium batteries which suffer permanent capacity degradation or internal copper dendrite shorting when discharged below threshold levels, Na-ion cells use aluminum substrate current collectors on both terminals. They can be safely stored and transported at 0V with zero fire risk, eliminating strict Hazmat surcharge barriers during shipping.
We provide full OEM/ODM branding flexibility, including custom sheet-metal metal casing dimensions, color schemes, silk-screen logos, custom wire harness connectors, specialized BMS firmware configuration, and white-label mobile monitoring apps.
Sodium-ion possesses exceptionally high ionic conductivity in liquid electrolytes, enabling continuous high C-rate discharges (up to 5C-10C peak current). This makes it suitable for dual-purpose applications such as microgrid energy storage and cold-weather engine starting down to -45°C.
We support scalable procurement stages: small-batch evaluation samples for engineering verification (1–5 units) up to container-load commercial supply shipments (20GP/40HQ) with custom client branding.
