Chinese electric-vehicle makers are increasingly bringing battery development in-house, a trend that industry observers say signals the sector's maturation rather than a simple competitive scramble. According to PCauto, a Chinese automotive news outlet, Xiaomi, Li Auto, Nio, GAC, Chery and Leapmotor have recently announced plans to self-develop and produce battery cells, from cell chemistry and structural design to full-scale manufacturing.
The move reflects a desire to break free from the homogeneity of standardized battery packs supplied by third-party manufacturers. Traditionally, automakers purchased off-the-shelf packs and focused only on vehicle integration, leaving little room to tailor energy storage to specific models or driving scenarios. By taking control of material selection, structural design and thermal management, companies can now bind the battery more closely to the vehicle, addressing key pain points such as energy consumption, fast-charging capability, safety and range. Xiaomi's Longarm battery and Chery's Rhino battery are cited as examples of this new approach, along with advances in cell-to-chassis (CTC) technology.
Supply chain security and cost control
Supply chain resilience is another driver. The battery industry has historically been highly concentrated, leaving automakers dependent on a few large suppliers and exposed to supply disruptions and limited pricing power. By self-developing or forming joint ventures to build factories, automakers aim to secure supply and reduce costs through vertical integration. This, in turn, could lead to lower vehicle prices and better value for consumers.
The trend is also reshaping the broader industrial ecosystem. Batteries are often described as the "heart" of an electric vehicle, and automakers' deeper involvement is pushing innovation in high-energy-density cells, longer-life batteries and solid-state technology. Rather than displacing dedicated battery makers like CATL, the entry of automakers is expected to foster a dynamic where both sides push each other to improve, creating a more competitive and innovative supply chain.
Challenges ahead
Self-developing batteries is not without hurdles. The technology is complex, upfront investment is heavy and returns take years to materialize. Yet PCauto argues this is a necessary step for automakers aiming for premium positioning and technological autonomy. The shift from buying standardized components to defining core technology marks a departure from the industry's earlier, more extensive growth phase, toward a stage driven by technology and value creation.
For the Chinese EV market, where competition is intense and price wars have been common, battery self-development could become a key differentiator. Automakers that master this capability are likely to gain a competitive edge, according to the report. As the industry evolves, the ability to innovate in battery technology may well determine which companies lead the next phase of growth.
