en.Wedoany.com Reported - Lin Jiubiao, CTO of CATL's domestic energy storage solutions, stated during an industry exchange event at the 2026 SNEC International Solar Photovoltaic and Smart Energy Conference that sodium-ion batteries have entered a full productization era. The event, hosted by the News and Publicity Center of the Ministry of Industry and Information Technology, focused on the technology and applications of the sodium-ion battery energy storage industry.

In recent years, industry attention on sodium batteries has primarily centered on the battery cells themselves. However, as industrialization progresses, the market is increasingly concerned about whether sodium batteries can establish a complete product system. CATL has completed its product layout from cells to systems.

According to reports, CATL has launched a complete energy storage unit consisting of a 3MWh DC compartment and a 3MW step-up converter integrated machine. It adopts a "one shell, dual core" platform solution, achieving the same size design for sodium and lithium battery systems, allowing flexible switching based on demand. On the technical front, CATL has restructured the electrochemical model around the characteristics of sodium-ion batteries, solving mass production challenges such as moisture control and gas generation in hard carbon electrodes. The product features a wide temperature range operation capability, maintaining stable performance even in extreme environments, with a cycle life of up to 15,000 times.

Industry insiders believe that with the simultaneous maturation of cells, systems, and application solutions, the sodium battery industry is transitioning from the question of "whether there are sodium batteries" to a new phase of "whether there are mature sodium battery systems."
