EV Supply Chain Overview
This section covers the supply chain for electric vehicles and electric equipment (EV/EE). The EV supply chain spans the full physical lifecycle of electrification hardware: from critical elements extracted from the Earth, through refining and battery, motor, and power-electronics manufacturing, to vehicle assembly, gigafactory operations, and end-of-life recycling. This pillar maps the industrial backbone of electrification — where value is created, where bottlenecks exist, and how reshoring, vertical integration, and clean-energy alignment are reshaping the landscape.
Upstream: Critical Materials
Critical Elements and REE
The upstream supply chain begins with critical elements such as lithium, nickel, cobalt, manganese, graphite, copper, and rare earth elements (REEs) like neodymium, praseodymium, dysprosium, and terbium. These elements are sourced from hard rock mines, brine deposits, and other geological resources. Mining, beneficiation, and early concentration define the physical availability and base cost structure for every battery cell, motor, and power-electronics device that follows.
Raw Materials and Mining
Mined ores, brines, concentrates, and other unrefined feedstocks extracted from global mining regions. These materials require significant chemical and metallurgical refining before they become usable inputs.
Processed Materials and Refining
Refining and chemical processing convert mined ores, concentrates, and brines into high-purity, battery- and motor-ready chemicals. This includes lithium hydroxide and carbonate, nickel and cobalt sulfates, purified graphite, separated rare earth oxides, and high-purity copper. At this stage, energy use, environmental controls, and regional policy shape both cost and geopolitical risk. For many materials, refining capacity rather than raw resource availability is the true bottleneck.
Midstream: Engineering & Manufacturing
This are the Tier-1 and Tier-2 vendor ecosystems that span materials, motors, battery systems, sensors, electronics, and manufacturing equipment.
Engineered Materials
Midstream begins where refined chemicals and purified metals are converted into engineered materials that are directly used in components. In the battery supply chain, this includes cathode active materials (CAM), anode active materials (AAM), separators, electrolytes, binders, conductive additives, and coated copper and aluminum foils. For motors and power electronics, it includes magnet powders and laminated steels for traction motors, and silicon carbide (SiC) and gallium nitride (GaN) substrates and epitaxial wafers for power semiconductors.
Component Manufacturing
Component manufacturing converts engineered materials into finished subsystems that Tier-1 and Tier-2 OEMs integrate into vehicles and infrastructure. This includes the following:
Traction Motors and Magnets
Traction motors, stators, rotors, permanent magnets (NdFeB), magnet wire, laminations, housings, cooling, and related manufacturing processes.
HV/LV Electrical and Power Electronics
Inverters, onboard chargers, DC–DC converters, junction boxes, wiring harnesses, low-voltage controllers, high-voltage safety components, and SiC/IGBT power devices that define vehicle efficiency and performance.
ADAS / AV Technology Stack
Sensors (camera, radar, lidar), domain controllers, inference compute, sensor-fusion systems, telematics, and the electronics and software stack enabling advanced driver assistance and autonomy.
Production Equipment
Production equipment vendors, testing systems, automation providers, and third-party engineering services that enable gigafactory-scale throughput.Downstream: Assembly & Integration
System and Vehicle Assembly
System integration brings batteries, motors, power electronics, thermal systems, wiring, and control electronics together into complete platforms and vehicles. This includes skateboard and platform architectures, high-voltage and low-voltage integration, ADAS and AV integration, functional safety, cybersecurity, and diagnostics.
Gigafactories and Production Footprint
Gigafactories are the large-scale manufacturing sites where upstream and midstream supply chains converge into finished products. They include battery cell plants, battery pack plants, motor and power-electronics plants, and final EV assembly facilities. These facilities anchor regional electrification ecosystems.
Recycling and End of Life
Recycling and end-of-life processing close the loop for batteries, motors, power electronics, and vehicles. This includes collection and logistics, pack disassembly, black-mass production and processing, hydrometallurgical and pyrometallurgical recovery of lithium, nickel, cobalt, manganese, graphite, copper, and REEs, as well as magnet and electronics recycling.
End-to-End (E2E) Software

Why Supply Chains Matter
- EVs depend on a deep, multi-stage supply chain that includes mining, refining, chemical processing, engineered materials, cells, packs, motors, inverters, control electronics, and final assembly.
- Batteries and power electronics concentrate the highest cost, complexity, and geopolitical risk across the entire stack.
- Material availability and processing capacity (lithium, nickel, cobalt, manganese, graphite, copper, rare earth elements) remain rate-limiting factors for global EV adoption.
- China currently dominates refining, cathode and anode materials, magnet manufacturing, and battery cell production — creating dependencies and concentration risk.
- National and regional industrial policies (IRA, BIL, EU Net-Zero Industry Act) are accelerating reshoring and diversification of key supply-chain stages.
- Recycling and circularity are emerging as strategic levers for long-term cost, security, and sustainability.
