Global battery markets are undergoing a fresh round of consolidation, with Chinese manufacturers widening their lead even as electric-vehicle deliveries falter. Data from SNE Research for January 2026 shows global EV deliveries slipped 2.1% year‑on‑year to 1.218 million vehicles, but total battery capacity fitted to those vehicles rose 10.7% to 71.9 GWh—a sign that cars are being equipped with larger packs and that demand is shifting toward higher‑end, longer‑range models.
Chinese suppliers were the principal beneficiaries. Six Chinese firms among the top ten battery makers supplied a combined 52.7 GWh in January, lifting their share of global installed EV battery capacity from 68.3% a year earlier to 73.3%. At the same time, the three major South Korean groups—LG Energy Solution, Samsung SDI and SK on—saw their combined market share collapse to 12.0% from 16.3% a year ago.
Part of that retrenchment reflects geography: North America, and the United States in particular, experienced the steepest downturn in EV sales in January. The termination of a major federal tax‑credit regime at the end of September 2025, together with tighter localisation rules for incentive eligibility, disrupted production and delivery schedules for western automakers and their battery suppliers. For Korea’s exporters—who rely heavily on a few large clients and the North American market—those policy shifts have translated into sharply lower volumes.
The numbers matter for more than headline market shares. Battery manufacturing is a scale business with steep learning curves: market concentration around Chinese producers implies faster cost reduction, greater control over cell chemistry roadmaps and enhanced bargaining power across the supply chain for nickel, lithium and other critical inputs. For automakers, heavy reliance on a small group of Chinese and a shrinking pool of Korean suppliers raises questions about resilience, price leverage and political risk as governments weigh industrial subsidies and security of supply.
Expect a two‑track industry response. Korean and other non‑Chinese players will accelerate localisation—building plants closer to automaker assembly lines in North America and Europe, and striking long‑term offtake agreements to stabilise volumes. Chinese groups, buoyed by home demand and export momentum, may push further into overseas capacity and proprietary technologies such as fast‑charging cells, thereby locking in advantages that could be hard to overturn.
The short term will see winners and losers by market, but the long‑term dynamic is clear: scale, policy alignment and access to raw materials will increasingly determine which battery firms set prices, define standards and influence the next phase of the EV transition.
