Battery Supply Chain
The battery supply chain spans from the extraction of critical minerals (lithium, cobalt, nickel, manganese) through chemical processing and cell manufacturing to final assembly into electric vehicles and grid-scale energy storage systems. It is the enabling infrastructure of the global energy transition — and the most geopolitically contested supply chain of the 2020s.
Step-by-Step Value Chain
4 steps from upstream extraction to end use. 2 chokepoints where supply disruptions have systemic impact.
Where This Chain Is Most Vulnerable
Chokepoints are steps where geographic concentration, technical barriers, or long lead times create structural supply risk with limited short-term alternatives.
Critical Mineral Mining
Geographic concentration of lithium (Lithium Triangle) and cobalt (DRC) with 7-15 year mine development cycles creates structural supply inelasticity. No near-term substitutes for cobalt in NMC chemistries.
Geopolitical — SovereigntyBattery Chemical Processing
China controls ~80% of global battery-grade chemical refining. Export controls on precursor cathode active materials would immediately constrain cell manufacturing globally, with no short-term alternative capacity.
Geopolitical — Competitive ControlDetailed Step Breakdown
Each step's role in the chain, key data points, and chokepoint detail where applicable.
Mining of Other Non-Ferrous Metal Ores
Extracts the four primary battery minerals from geologically concentrated deposits. Supply is structurally constrained: lithium is concentrated in the Lithium Triangle (Chile, Argentina, Bolivia) and Australia; cobalt is 70%+ from the DRC. Neither mineral has a near-term substitute in mainstream cell chemistries.
- Cobalt: ~72% of global production from DRC as of 2024
- Lithium: concentrated in Chile (37%), Australia (29%), Argentina (11%)
- Nickel: Indonesia dominant (48%), Philippines secondary (10%)
- Artisanal and small-scale mining (ASM) accounts for ~15-20% of DRC cobalt — primary ESG exposure point
Manufacture of Basic Chemicals
Transforms raw mineral ore concentrates into battery-grade chemicals: lithium hydroxide monohydrate (LiOH·H₂O), cobalt sulfate, nickel sulfate, manganese sulfate, and precursor cathode active material (pCAM). This is the most technically demanding transformation step and the one with the highest geographic concentration risk — China controls approximately 80% of global battery chemical refining capacity.
- Battery-grade LiOH requires >99.5% purity — distinct from industrial-grade production
- China processes ~80% of global lithium into battery-grade chemicals (Benchmark Mineral Intelligence, 2024)
- US IRA domestic content requirements are incentivising ex-China pCAM investment
- LFP chemistry (lithium iron phosphate) uses no cobalt/nickel but still requires battery-grade lithium
Manufacture of Batteries and Accumulators
Converts battery-grade chemicals and electrode materials into finished cells (cylindrical, prismatic, or pouch format), then assembles cells into modules and battery packs. This is the highest value-add step in the chain: a battery pack for a mid-size EV (75 kWh) at 2024 prices represents ~$7,500-$9,000 in cell cost alone. Cell manufacturing is extremely capital-intensive (a 10 GWh gigafactory requires ~$1B capex) with high yield sensitivity.
- Global cell manufacturing capacity is heavily concentrated in China (CATL, BYD) and South Korea (LG, Samsung, SK)
- Gigafactory build-out accelerating in EU and US under IRA/IPCEI incentives
- Cell format is converging on cylindrical (4680) and LFP prismatic for passenger EVs
- Pack integration is increasingly done by OEMs (cell-to-body, cell-to-pack architectures)
Manufacture of Motor Vehicles — ev manufacturing
The dominant demand driver for battery packs, consuming ~65-70% of global cell output by energy (kWh). EV OEMs set cell format, chemistry, and performance specifications, giving them significant buyer power over cell manufacturers. Platform integration (cell-to-body, cell-to-pack) is internalising more of the pack assembly value from step 3 into step 4.
- Global EV sales: ~14M units in 2023, targeting ~40M by 2030 (IEA)
- China accounts for ~60% of global EV sales (2023)
- OEMs increasingly signing direct offtake agreements with miners (step 1) to secure supply
Electric Power Generation, Transmission and Distribution — grid storage
Rapidly growing secondary demand for batteries as grid-scale storage. Battery Energy Storage Systems (BESS) address the intermittency challenge of solar and wind generation. This segment currently consumes ~20-25% of global cell output and is projected to grow faster than EV demand through the 2030s as renewable penetration deepens.
- BESS deployment growing at ~40% CAGR (2022-2027, Wood Mackenzie)
- LFP chemistry dominates grid storage (lower cost, better cycle life than NMC)
- Grid storage is less specification-sensitive than EV — accepts second-life EV cells
Where Margin Is Captured
Rough indication of value capture at each step — what creates pricing power and where the chain's economic returns concentrate.
| Step | Value Capture | Margin Driver |
|---|---|---|
|
Step 1
Mining of Other Non-Ferrous Metal Ores
|
Commodity pricing with periodic spikes. Mining companies earn windfall margins during demand surges but face price collapse in oversupply. Capital intensity and permitting barriers limit new entrants. |
|
|
Step 2
Manufacture of Basic Chemicals
|
Technical process know-how and geographic concentration sustain margins. Battery-grade specification (>99.5% purity) differentiates from commodity industrial-grade chemical production. |
|
|
Step 3
Manufacture of Batteries and Accumulators
|
Highest value-add transformation in the chain. Cell manufacturing IP, yield management, and long-term supply agreements with OEMs create durable margin. CATL and LG Chem consistently earn 15-25% gross margins on cells. |
|
|
Step 4 — Ev Manufacturing
Manufacture of Motor Vehicles
|
Brand, software, and service revenue increasingly differentiate EV margins. Hardware margins on the vehicle itself are thin (Tesla excluded). Battery cost remains the largest single variable cost (~30-40% of vehicle BOM). |
|
|
Step 4 — Grid Storage
Electric Power Generation, Transmission and Distribution
|
Highly competitive on LCO (levelised cost of storage). Utility operators buy on $/kWh and warranty terms — commoditised procurement. System integrators earn modest margins on engineering and commissioning. |
Industries That Enable This Chain
These industries do not transform the primary product but are essential for the chain to function — logistics, finance, professional services, and enabling technology.
Manufacture of Electronic Components and Boards
Battery Management Systems (BMS), cell-level sensors, protection circuits, and state-of-charge monitoring electronics. BMS quality directly determines cell longevity, thermal safety, and warranty outcomes.
Warehousing and Storage
Temperature-controlled storage for battery-grade chemicals (moisture-sensitive) and finished cells (thermal runaway risk). Hazardous goods classification adds specialist infrastructure requirements.
Other Monetary Intermediation
Project finance for gigafactory construction ($1-4B per facility), trade finance for mineral commodity flows, and working capital facilities. Capital availability is a binding constraint on the pace of ex-China capacity build-out.
Other Professional, Scientific and Technical Activities
Supply chain due diligence (OECD guidelines, EU Battery Regulation), ESG auditing of upstream mining operations, geopolitical risk advisory, and customs/trade classification consulting for critical minerals.
