Sodium Batteries Are Entering the Spotlight – A New Era of Energy Storage

Publish: September 25,2025   Last Upadate: September 25,2025   Tag:  

Sodium-ion batteries are speeding up their path to commercialization. Recently, CATL’s sodium-ion battery became the first in the world to pass the new national standard, and a megawatt-level sodium storage station in Hubei has started running successfully. These breakthroughs mark a turning point for the industry.

At this key moment, HJ Group (Shanghai Huijue Network Communication Equipment Co., Ltd.) is stepping forward as a leader in energy storage system integration, embracing this new wave of technology with advanced system design and strong innovation capability.

Why Sodium Batteries?

Sodium-ion batteries stand out for a few clear reasons:

Resources: Sodium is far more abundant and evenly distributed than lithium. This means no worries about raw material shortages or price spikes.

Cold Resistance: Even at -20℃, sodium batteries keep more than 90% of their capacity. Perfect for cold regions.

Safety: No fire or explosion risks during extreme tests like nail penetration or drilling.

Cost: Around 30% lower than lithium-ion per kWh – a game-changer for large-scale projects.

These advantages make sodium batteries especially attractive for commercial and utility-scale storage, where safety, cost, and wide temperature performance are key.

HJ Group’s Integration Strategy

As a system integrator, HJ knows sodium-ion will reshape the industry. We’ve already been preparing on several fronts:

Thermal Management: Our new liquid cooling solution keeps cabinet temperature differences within 2.5℃. This ensures sodium batteries work in their sweet spot.

Flexible Architecture: We’re building modular platforms that support both sodium and lithium chemistries. Customers can easily adopt the latest cells without redesigning the whole system.

Smart Control: Our R&D team is developing sodium-specific BMS/EMS algorithms, modeling charge/discharge behavior and aging patterns. This extends lifespan and boosts performance.

Building a Sodium Ecosystem

HJ believes no company can do it alone. That’s why we’re partnering with cell makers like CATL, as well as materials suppliers, to push sodium storage solutions toward faster commercialization.

At the same time, we’re testing sodium integration across multiple product lines:

Telecom Base Stations: Safer, wide-temp sodium batteries make remote stations more reliable.

Distributed Storage: Lower costs shorten project payback periods.

Residential Storage: Safety advantages reduce user concerns and speed up adoption.

Looking Ahead

HJ Group is not just following trends – we aim to lead. With sodium commercialization accelerating, we’re doubling down on R&D and ecosystem partnerships to deliver future-ready storage solutions.

We see a future where lithium and sodium co-exist, and integrators with multi-chemistry platforms will take the lead. HJ Group is ready to be one of them.
