EV Battery Cells (Li-Ion): Market Size & Forecast 2026

The global EV battery cell market reached approximately USD 145 billion in 2025, anchored by passenger EV demand accounting for roughly 78% of end use. Cathode active material drives 35% of the USD 95 reference cell cost, with battery-grade lithium carbonate spot benchmarks ranging from USD 10,200 to 11,500 per metric tonne across US, EU, and Asian markets in Q2 2026. The sector added approximately 1,200 GWh of global nameplate capacity in 2024, and the IEA's Global EV Outlook 2026 confirms deployment reached 1.74 TWh across EV and stationary storage in 2025, four years ahead of the 1 TWh milestone originally projected for 2030. > **Analyst Take.** Our view: the consensus 18% CAGR is credible but concentration risk is systematically underpriced by buyers. CATL and BYD together installed 659.5 GWh in 2025, representing 55.6% of global EV battery usage, that duopoly dynamic does not ease m
