Phase 2 is planned to reach an annual capacity of 10 to 12 GWh. Once completed, the combined annual capacity of the two phases will exceed 20 GWh. Through this clustered production model, the two companies aim to enhance industrial efficiency, strengthen cost competitiveness, and support Chongqing in building a trillion-yuan high-end intelligent connected new energy vehicle industrial cluster.
Supercharging and Energy Replenishment Ecosystem: The cooperation will focus on supercharging networks and battery services, creating a full-lifecycle service system to further enhance the user experience.
● Global Market Development: In addition, the two companies will work together to explore overseas markets, including Europe, the Middle East and Central Asia, bringing high-quality products and services to more global customers and supporting the transition to intelligent electric mobility in key markets.
Looking ahead, CATL will continue to uphold a long-term approach, leveraging technological innovation and efficient industrial-chain collaboration to support the high-quality development of the new energy vehicle industry.
