Chinese battery manufacturing giant CATL has unveiled what it says is the world’s first real-world validated sodium-ion energy storage solution, with global deliveries to begin in the middle of 2027.
CATL’s new Tener Sodium Energy Storage System was unveiled on Tuesday at an event at Intersolar Europe 2026 in Munich, Germany, boasting full commercial maturity across the technology, production capacity, and supply chain readiness.
Sodium is 1,000-times more abundant than lithium and distributed widely across the planet, and is seen as a potentially economic substitute for lithium-ion based batteries, although they have yet to reach commercial scale.
“CATL is committed to promoting energy independence around the world while delivering long term value for our customers,” said William Wu, director of CATL’s Energy Storage Technology Center.
“To achieve this we have made it our mission to develop a new battery chemistry based upon abundant resources available across all continents, one that can support the energy needs of all eight billion people, while offering longer cycle life and enhanced safety.
