Seres and CATL Expand Strategic Battery Alliance
TREE NEWS reports: On October 10, Seres Group and CATL signed a long-term strategic cooperation agreement in Chongqing, accelerating the second phase of their ‘factory-in-factory’ project, collaborating on ultra-fast charging networks and battery services, and jointly expanding into European, Middle Eastern, and Central Asian markets. The AITO brand will continue to feature CATL batteries across its entire lineup, while Seres’ new AIVA brand will adopt a battery-swapping model, with CATL supporting its overseas expansion.
The partnership now encompasses three concrete tasks: expanding manufacturing capacity for AITO, arranging battery-swapping and overseas operations for AIVA, and deepening cooperation across production lines, in-vehicle services, and new market development.
Market Implications
1. Battery Supply Chain Consolidation
CATL’s ‘factory-in-factory’ model—where battery pack production occurs within Seres’ manufacturing facility—represents a significant shift in automotive supply chain integration. The first phase, operational since June 2025, produces two CTP 2.0 high-end battery pack lines. The second phase, with an annual capacity of 10-12 GWh, will bring total capacity to over 20 GWh. This vertical integration reduces logistics costs and improves production scheduling, potentially boosting Seres’ operating margins.
2. Competitive Dynamics in China’s EV Sector
Seres’ decision to rely on CATL for battery pack production contrasts with competitors like Li Auto, which has pursued in-house battery cell development and pack assembly. This divergence highlights different strategic approaches: Seres prioritizes supply chain efficiency and capital preservation, while others seek greater vertical integration. For CATL, securing long-term contracts with major automakers reinforces its dominant market position.
3. Overseas Expansion and Battery Swapping
The AIVA brand, jointly invested by Seres and CATL (CATL holds ~9.89% via its investment arm), will use battery swapping as its primary overseas market strategy. Battery swapping requires standardized infrastructure and ongoing operational support, creating recurring revenue streams for CATL. This model could accelerate EV adoption in markets with limited charging infrastructure, particularly in the Middle East and Central Asia.
4. Investment Considerations
- CATL (300750.SZ): The expanded partnership strengthens CATL’s order book and reinforces its leadership in battery technology. The battery-swapping angle adds a service-based revenue component.
- Seres (601127.SH): Securing long-term battery supply reduces production risk and supports volume growth for AITO. However, reliance on a single supplier could pose concentration risks.
- EV Supply Chain: The ‘factory-in-factory’ model may become a template for other automakers, benefiting equipment suppliers and logistics providers.
- Commodities: Increased battery production supports demand for lithium, nickel, and cobalt, though pricing will depend on broader EV demand trends.
Key Takeaways
- Seres and CATL are deepening integration through localized battery pack production, with Phase 2 adding 10-12 GWh capacity.
- The AIVA brand’s battery-swapping model and overseas expansion represent a new growth vector for both companies.
- CATL’s investment in AIVA (9.89%) aligns its interests with Seres’ overseas success.
- Investors should monitor execution risks in overseas markets and potential margin impacts from battery-swapping infrastructure investments.
