CATL's Groundbreaking Sodium-Ion Energy Storage System

In a significant advancement for energy technology, CATL officially launched its TENER Sodium energy storage system in Munich, Germany, on June 22, 2026. This innovative solution is the first validated sodium-ion energy storage system that is commercially viable, setting a new benchmark in the industry.

Turning Vision Into Reality

William Wu, the Director of CATL's Energy Storage Technology Center, expressed the company’s mission to promote global energy independence while delivering long-term value to its customers. He stated that the goal was to develop new battery technology based on abundantly available resources, ensuring that energy needs for all eight billion individuals on the planet can be met. The introduction of sodium-ion technology is seen as a critical step in achieving this objective, as it can potentially work alongside lithium-ion technology to form the dual backbone of future energy storage systems.

As the share of renewable energy sources continues to grow and the power demands fueled by artificial intelligence increase, energy storage is evolving from being merely supportive to becoming critical infrastructure for the global energy grid. Traditional energy storage systems have primarily relied on lithium-based technologies, which pose supply chain risks due to concentrated resources and price volatility. Sodium, on the other hand, is over 1,000 times more abundant than lithium and is known for its better performance under extreme temperatures, enhanced safety, and cost-effectiveness.

Advanced Features of TENER Sodium

The TENER Sodium system boasts several key benefits that enhance its appeal:
1. Modular Architecture: Each module weighs around 42 tons, facilitating easier project implementation. For a 1 GWh facility, only 34 units are necessary.
2. Configuration Flexibility: The architecture allows for various storage durations, catering to specific project requirements with options for 1, 2, 4, 6, or 8 hours of energy storage.
3. Reduction in Maintenance Costs: Quick isolation and replacement of defective modules enhance system availability while minimizing operational costs.

To support its sodium-ion technology, CATL has developed a plant-level platform that optimizes energy management:

• - Voltage Regulation: A specialized bi-directional voltage regulation system aids in maintaining optimal performance across a broad voltage range.
• - Battery Management System (BMS): CATL’s BMS for sodium-ion systems improves state-of-charge estimation and increases tolerance to overcharging, delivering an additional safety margin.
• - Energy Efficiency: Unique designs that reduce thermal effects and the energy consumption of auxiliary systems contribute to significant operational cost savings over time.

Commitment to Research and Development

With nearly a billion euros invested in research since 2016, CATL has developed its sodium-ion technology from a conceptual phase to a robust commercial-ready product. The team of over 300 R&D experts has amassed an impressive 1,600 patent families and has established a fully integrated manufacturing process from materials to battery cells. Currently, CATL is poised to deliver tens of thousands of tons of anode and cathode materials, anticipating continued reductions in production costs as the technology matures.

Strategic Partnerships

CATL is forming strategic alliances with system integrators to create a comprehensive ecosystem for sodium-ion energy storage. This includes collaboration on cellular research, system delivery, product testing, and commercial applications. With substantial investments in production capacity, CATL is prepared for large-scale deployment, beginning with customer deliveries in China set for later this year and international shipments expected by June 2027.

The Future of Energy Storage

The unveiling of the TENER Sodium energy storage system signifies a monumental shift in energy storage technology, ushering in a new era where sodium and lithium serve as the foundational elements of next-generation energy solutions. As CATL continues to innovate and collaborate with global partners, the company remains committed to realizing a sustainable, cost-effective, and resilient energy future.
