Supply Chains Hub

ElectronsX maps the supply chains behind electric vehicles (EVs), batteries, battery energy storage systems (BESS), robots, drones, EV charging equipment (EVSE) and solar power. Each domain has its own hub page, listed below.

The domains share suppliers. The same lithium cell, silicon carbide (SiC) wafer and harmonic drive go into EVs, humanoid robots, BESS and grid infrastructure, so ElectronsX maps the chains as one connected graph. The Supply Chain Convergence Map shows where they share nodes and compete for the same constrained resources.

Supply Chain Domains

What Each Domain Covers

• Upstream Materials: Critical minerals, raw mining, and refined materials feeding all downstream chains: lithium, cobalt, nickel, graphite, REE, silicon carbide, copper.
• EV Supply Chain: Full EV stack from battery cells through final assembly, with 9 nodes covering batteries, motors, power electronics, thermal, networking, SDV systems, and gigafactories.
• Battery Supply Chain: CAM, AAM, separators, electrolytes, foils, and cell cans through cell and pack manufacturing, covering LFP, NMC, LMFP, and solid-state.
• Robot Supply Chain: Humanoid and robotic platform supply chains: actuators, harmonic drives, servo motors, GaN joint drives, tactile sensors, edge inference compute.
• Drone & UAV Supply Chain: Aerial platform supply chains: brushless motors, ESCs, GaN power stages, LiDAR arrays, compact compute, structural materials.
• BESS Supply Chain: Battery energy storage system supply chains, from lithium cells through pack integration, PCS power electronics, BMS, and turnkey system assembly.
• EVSE & Depot Supply Chain: EV charging equipment and fleet depot supply chains: DCFC cabinets, MCS systems, power conversion hardware, networking, installation materials.
• PV Supply Chain: Solar photovoltaic supply chain from polysilicon through wafer, cell, module, inverter, and balance of system, with US reshoring coverage.
• Gigafactories & Plants: Battery cell and EV manufacturing facilities: capacity, chemistry, location, status, IRA eligibility, and OEM profiles for major global gigafactories.

Sector Overlays and Convergence

Sector Overlay Supply Chains

Off-highway equipment, marine vessels and aviation use the EV component stack under harsher environments and stricter certification. See: Sector Overlay Supply Chains

Shared Chokepoints

Several domains draw on the same materials, components and manufacturing capacity at once:

• SiC power semiconductors: used in EV traction inverters, BESS power conversion systems (PCS), EVSE DC fast charging (DCFC) cabinets, solar inverters and grid infrastructure. A SiC wafer shortage hits all five at once. See: SiC & GaN - The Universal Power Substrate
• Harmonic drives and strain-wave gearboxes: the primary actuator for humanoid robots. Supply is concentrated in Japan (Harmonic Drive Systems, Nabtesco), with Chinese OEMs scaling. At projected humanoid volumes, harmonic drives and GaN joint actuators become the robot supply chain's equivalent of the SiC wafer problem.
• GOES electrical steel: grain-oriented electrical steel (GOES) goes into EV traction motors, transformer cores for gigafactory energization and grid transformer cores. US domestic production is highly constrained.

Materials, Components and Assembly

The EV Supply Chain hub walks through these stages from mine to vehicle. The pages below cover them for all domains.

Critical Materials

Upstream inputs are lithium, nickel, cobalt, manganese, graphite, copper and rare earth elements (REE) including neodymium, praseodymium, dysprosium and terbium, sourced from hard rock mines and brine deposits. For many materials, refining capacity is the bottleneck, not raw resource availability. China dominates refining, cathode and anode materials, magnet manufacturing and battery cell production.

• Critical Elements Directory
• Raw Materials & Mining
• Refined Materials - Batteries, Motors, Power Electronics
• Battery Upstream Materials

Component Layers

Tier-1 and Tier-2 suppliers turn refined materials into engineered components, where cost, performance and geopolitical risk are set.

Assembly, Gigafactories and Recycling

Gigafactories anchor regional electrification ecosystems and need 50-150+ MW of power per site, which ties them back to energy and grid supply chains. Recycling recovers lithium, nickel, cobalt, manganese, graphite, copper and REE through hydrometallurgical and pyrometallurgical processes and feeds them back into cathode active material production.

• EV Final Assembly
• Gigafactories & Battery Plants
• Cell Manufacturing Process
• Pack Manufacturing Process
• Battery Manufacturing Process Flow

Industrial Policy

The Inflation Reduction Act (IRA), the Bipartisan Infrastructure Law (BIL) and the EU Net-Zero Industry Act are accelerating reshoring and diversification away from Chinese supply.

End-to-End Supply Chain Software

Planning and execution software across the EV supply chain, with vendor lists and electrification use cases:

• E2E Software Stack Overview
• Enterprise Resource Planning (ERP)
• Supply Chain Management (SCM)
• Manufacturing Execution (MES / MRP)
• Product Lifecycle Management (PLM)
• Digital Twin Software
• Energy Management (EMS)

Upstream: SemiconductorX

ElectronsX covers supply chains from the module and component level up through systems and applications. Wafer fabs, substrate materials, SiC boule growth, GaN epitaxy, foundry capacity and advanced packaging are covered on SemiconductorX, part of the SiliconPlans network. The two sites meet at power electronics, ADAS compute and actuator motor controllers.
