In a significant development for the electric vehicle supply chain, the first battery cell has recently been produced at a new $4 billion joint venture battery plant involving Xiaomi Corporation and Contemporary Amperex Technology Co., Ltd. (CATL). The milestone signals the facility is moving into mass production.
Plant Details and Production Timeline
The plant, operated by Times BAIC (Beijing) New Energy Technology Co., Ltd., is in the final stages of construction. The first production line is now active, and equipment for a second line is currently being commissioned. Official mass production is scheduled to commence in August of this year. The facility is projected to produce 7.5 GWh of battery cells throughout 2026, with full annual capacity reaching 15 GWh upon completion.
Joint Venture Structure and Strategic Location
Located in Beijing's Yizhuang Economic-Technological Development Area, the factory is strategically positioned adjacent to Xiaomi's automobile manufacturing plant. The joint venture is backed by four major shareholders: CATL holds a 51% controlling stake, state-owned BAIC holds 39%, state-owned Jingneng holds 5%, and Xiaomi Auto holds the remaining 5%. This facility represents Xiaomi's first equity investment in a power battery factory and serves as CATL's inaugural battery production base in northern China.
Advanced Manufacturing and Production Standards
With a total investment of 4 billion yuan, the plant is designed as a high-standard "Lighthouse Factory" and "Zero-Carbon Factory." It incorporates CATL's proprietary super production line technology, featuring highly automated, flexible, and high-speed assembly lines. The facility integrates 5G connectivity, artificial intelligence, and digital twin technologies, and includes 6,800 quality control points. This advanced setup aims to reduce cell defect rates to the parts-per-billion level while achieving a production speed of one cell per second.
Supply Chain Implications and Market Impact
The plant's operation marks a significant step in the deep integration between automakers and battery manufacturers, entering the commercial market phase. It is expected to provide a stable supply of power battery products to automotive clients in the Beijing-Tianjin-Hebei region, including BAIC, Xiaomi, and Li Auto.
Xiaomi's Broader Battery Strategy
This development coincides with Xiaomi's accelerated efforts to secure its core automotive components supply chain. In late April, Xiaomi established Beijing Xiaomi Jingxu Technology Co., Ltd. in Beijing's Daxing District. The new subsidiary, with a registered capital of 10 million yuan, focuses on manufacturing key components, including electric motors and batteries, pointing directly to the core "three-electric" systems for smart vehicles. Industry analysis suggests the company will concentrate on battery pack (PACK) system integration, working in tandem with the new joint venture plant to solidify Xiaomi's comprehensive battery industry chain strategy, which encompasses upstream investments, joint ventures for capacity, and in-house integration breakthroughs.
Diversifying the Supplier Network
Furthermore, Xiaomi is actively diversifying its battery supplier base. Recent reports indicate that for its upcoming "Xuntian" sub-brand and its first extended-range electric vehicle model, codenamed "Kunlun," Xiaomi will source batteries from several second-tier suppliers, including CALB and Sunwoda. This marks a shift from its previous reliance on top-tier suppliers like CATL and BYD.
A Multi-Layered Supply Chain Model
Through these moves, Xiaomi is constructing a multi-layered supply chain system. This model combines securing supply from top-tier cell manufacturers, ensuring local supply from its joint venture plant, developing in-house PACK technology to reduce costs, and engaging second-tier suppliers to mitigate risks. This approach is designed to address common industry challenges faced by EV makers, including cell capacity shortages, long lead times, volatile raw material costs, and over-reliance on a single supply source.
Logistical and Regional Advantages
The plant's proximity to Xiaomi's vehicle assembly plant offers significant logistical advantages. Cells produced on-site can be quickly assembled into battery packs and installed into vehicles, drastically reducing cross-regional transportation costs and storage times. This efficiency is expected to accelerate vehicle delivery and optimize overall production costs, enhancing the competitive pricing and profitability of Xiaomi's car models.
Regional Industrial Development
From a regional perspective, the launch of this flagship battery production base in northern China addresses a critical gap in the local supply of battery cells for the new energy vehicle industry in the Beijing-Tianjin-Hebei region. It changes the previous industry practice where local automakers had to source batteries from distant suppliers. Backed by the involvement of state-owned shareholders BAIC and Jingneng, the project synergizes with local energy, automotive, and component industry resources. It supports the development of an integrated new energy vehicle industrial cluster in Beijing's Yizhuang area. The plant's zero-carbon factory standards also align with the green, low-carbon development plans for the northern region's new energy industry, balancing economic benefits with ecological development goals.
Market Outlook and Industry Trend
Market observers believe that with the plant's official production start in August, Xiaomi's vehicle production capacity ramp-up will accelerate significantly, enhancing supply stability for both the new "Kunlun" extended-range model under the Xuntian brand and Xiaomi's existing pure electric vehicle lineup. Looking ahead, the cooperative model of equity ties between automakers and battery manufacturers, involving multiple stakeholders including government-backed enterprises, is likely to become more prevalent. Deep integration across the new energy vehicle industry chain, regionalized local supply, and a self-reliant, controllable supply chain are expected to remain key development trends.
