CATL Debuts World's First Field-Validated Sodium-Ion BESS, Bringing Sodium Storage to Commercial Reality
CATL says the modular system uses sodium-ion technology and is designed for GWh-scale deployment as shipments are set to reach 1 GWh by 2026.
- On Monday, Contemporary Amperex Technology Ltd. unveiled the TENER Sodium energy storage system in Munich, Germany, calling it the world's first field-validated sodium-ion energy storage solution.
- Conventional energy storage relies heavily on lithium, whose volatile prices and concentrated supply pose growing risks; sodium, 1,000 times more abundant, offers superior safety and extreme-temperature performance.
- Powered by the latest sodium-ion technology, TENER Sodium delivers more than 30 MWh of rated capacity and reduces system heat generation by nearly 30% while improving BMS overcharge tolerance by 20%.
- CATL will begin domestic deliveries this September, with global shipments scheduled for June 2027, having secured a three-year, 60 GWh contract with Beijing HyperStrong Technology.
- Chairman Yuqun Robin Zeng aims to scale sodium battery capacity to more than 100 GWh annually within five years, following a RMB 5 billion investment to expand Fuding base production lines.
