At a critical moment of global energy transition, sodium electricity is standing at the center of the historical stage

When the global energy storage market enters a trillion level expansion cycle, when the competition for lithium resources intensifies and the supply chain becomes fragile, and when the demand for uninterrupted and high security energy storage in AIDC (Artificial Intelligence Data Centers) is exponentially increasing, an underestimated electrochemical route is irreversibly reshaping the global energy landscape.

The 18th Shenzhen International Battery Technology Exchange Conference/Exhibition (CIBF2026) was grandly held at the Shenzhen International Convention and Exhibition Center from May 13th to 15th. As one of the most influential top exhibitions in the global battery industry, CIBF brings together leading companies and industry elites from dozens of countries and regions around the world.

CNAEPower, with its core sodium ion cylindrical/square battery cells and full scenario solutions, made a strong appearance at the CIBF International Battery Exhibition. With a complete product matrix and mature industrialization technology, CNAEPower fully demonstrated the hard core strength of CNAEPower to domestic and foreign merchants.
