Lithium-Ion Battery Cells

The Manufacturing Dominance Thesis

CATL and BYD control 55%+ of global lithium-ion cell production, and the cost gap to Western and Korean competitors is widening with every quarter of cumulative output. CATL produces LFP cells at $55-60/kWh fully loaded; the best Western equivalent is $95-110/kWh. This is not a labour cost story — it is a process learning, vertical integration, and scale story. CATL's Kittner facility produces more cells per year than all European factories combined. BYD's Blade Battery eliminated modules entirely, cutting pack cost 15-20%. The compounding effect of Chinese process learning means each TWh of cumulative production drives another 5-8% cost reduction. Western gigafactories arriving in 2027-2028 will compete against Chinese cost curves that have moved twice more by then. The structural advantage is manufacturing, not chemistry.

State of the art (2026)

As of mid-2026 the cell industry is defined by Chinese scale and falling prices. CATL holds roughly 40% of global EV-battery installations and BYD around 14% in the year to April; seven Chinese makers together command about 72%. BloombergNEF put 2025 average pack prices at $108/kWh – $84/kWh inside China – with the cheapest LFP stationary cells near $36/kWh. LFP and its manganese-rich M3P variant now dominate mass-market and grid deployment, pushing NMC towards premium range applications. Solid-state stays pre-commercial: QuantumScape inaugurated its Eagle pilot line in February 2026, while Toyota and Samsung SDI target limited output from 2027, every prior timeline having slipped.

The Chemistry Settlement Thesis

LFP has won the mass market. It now accounts for 60%+ of global EV cell deployments by volume, up from 30% in 2022. The cost advantage ($55-65/kWh vs $85-100/kWh for NMC), superior cycle life (3,000+ cycles vs 1,500), and thermal stability make it the default chemistry for standard-range EVs, commercial vehicles, and stationary storage. NMC 811 and NMCA retain the premium segment where gravimetric energy density matters — long-range luxury EVs, aviation, and defence — but the addressable market is smaller and margins are compressed. Solid-state remains 3-5 years from commercial scale: Toyota targets 2028 for pilot production, QuantumScape has yet to demonstrate automotive-grade cycle life at scale. The chemistry race for this generation is settled. The next generation will be fought on sodium-ion for low-cost and solid-state for premium, but neither disrupts the manufacturing incumbents — CATL leads in both.

The Geopolitical Control Thesis

Batteries are the new oil. Control of cell manufacturing determines control of the energy transition and transport electrification — every EV, every grid storage installation, every military energy system depends on cells. China controls 77% of global cell production, 90% of anode material, 70% of cathode material, and 60% of lithium refining. The US IRA and EU Battery Regulation are attempting to build parallel supply chains, but the $100B+ in announced Western gigafactory investment faces 60%+ delay or cancellation rates. The dependency is structural and will persist through at least 2030. This creates both risk (supply weaponisation, trade war escalation) and opportunity (the few Western manufacturers who achieve competitive scale become strategic national assets). The parallel to oil is precise: the resource that powered the 20th century determined geopolitical alignment; the manufactured component that powers the 21st century will do the same.
