DALIAN, China, Sept. 24, 2026 /CourierPR/ -- CBAK Energy Technology Limited, a China-based lithium-ion battery manufacturer and energy solutions provider, has announced a significant expansion plan for its operations in Nanjing. The company has signed an investment agreement for a 12 gigawatt-hour (GWh) sodium-ion battery project in Nanjing, Jiangsu Province. This project is part of CBAK Energy’s broader strategy to diversify its product offerings and meet growing demand for advanced battery technologies.
According to the agreement, the 12 GWh project will add substantial production capacity to CBAK Energy’s existing facilities. The company aims to advance this project in the second half of 2027, subject to securing necessary financing. This expansion is driven by strong demand for Model 60150 large cylindrical cells, which the company currently produces at its Nanjing facility. The facility already has a capacity of 4.5 GWh of annual Model 32140 cell production. The planned expansion will increase the total annual cell capacity to 10.5 GWh.
CBAK Energy’s expansion plans are part of a broader strategy to enhance its product portfolio and meet the increasing demand for high-power applications. The company’s products serve electric vehicles, light electric vehicles, energy storage systems, and other high-power applications. In January 2006, CBAK Energy became the first Chinese lithium battery manufacturer to be listed on the Nasdaq Stock Market.
The 12 GWh project is expected to generate an additional RMB4.8 billion to RMB5.0 billion (approximately US$712 million to US$741 million) in annual revenue at full capacity, assuming all output is sold. The project will cover cell manufacturing as well as module and battery pack integration. Development will proceed in phases, based on financing availability, customer demand, and project readiness.
CBAK Energy is also planning a separate 6 GWh expansion at its existing Nanjing facility by year-end 2026. This expansion will bring the total annual cell capacity to 10.5 GWh, more than doubling the current capacity of 4.5 GWh. At full capacity, this expansion could generate an estimated RMB2.4 billion to RMB2.7 billion (approximately US$356 million to US$400 million) in annual revenue.
The company is considering two Model 60150 production lines for the expansion. Given strong demand for Model 32140 cells, it may instead install one Model 32140 line and one Model 60150 line. The cell models and production-line configuration may be adjusted as market conditions and customer demand evolve.
