Lithium-Ion Battery Cells
Lithium-ion cell manufacturing is splitting into three demand pools: scaled EV and heavy-truck programs (Tesla, BYD, GM's Ultium Cells venture), defense-oriented drone and robotics cells (Amprius, SES AI), and stationary storage and RV or fleet batteries (Dragonfly, Microvast, Electrovaya). The recent evidence is uneven. Tesla and BYD show scale, and Amprius has secured a federal grant. Against that, U.S. EV demand has weakened after the loss of federal tax credits, tariffs and China export controls affect several filers, and several smaller cell makers have no recent activity or constraint disclosures on record.
Active institutional funds added a net $5.8 billion in Q2 2026, versus $1.4 billion in Q1 2026 — an inflow 326% larger. 40% of companies in this sub-theme saw increased active positions in Q2 2026.
Overview
This sub-theme covers companies that manufacture lithium-ion cells and battery packs for electric vehicles and stationary storage. It excludes pure mineral miners and system integrators that do not make cells. Participants differ by chemistry, scale and route to market. Tesla pursues vertical integration, including its own 4680 cells and Megapack storage products. BYD operates as a vertically integrated automaker-cell maker. GM sits mainly as an enabler: it co-operates cell production through the Ultium Cells joint venture with LG Energy Solution and holds equity stakes in cell developers and lithium resource companies. Specialist developers focus on differentiated cell technologies. Amprius works in silicon-anode cells and supplies AeroVironment's UAS programs. SES AI works in lithium-metal cells. Enovix and Solid Power are positioned in advanced cell and battery materials. Dragonfly Energy sells LFP-based batteries to RV OEMs such as THOR and to fleet operators. Competition runs across several arenas: SES AI competes with Microvast, Electrovaya and Stem in energy storage products, and with Amprius and QuantumScape in drone and robotics cells. Amprius competes with Samsung SDI and Enovix in high-performance cells. Tesla competes with ESS Tech in traditional lithium-ion energy storage. Cell makers depend on cross-border supply chains for materials, components and sometimes finished cells, so trade and industrial policy shape the economics. Many developers also rely on strategic partners or government support alongside capital markets.

The rollback removes a key federal demand-side driver for EV adoption in the U.S., weakening the investment case for pure-play EV manufacturers like Tesla, Rivian and Lucid while benefiting legacy automakers such as GM, Ford and Stellantis who can lean into higher-margin trucks and SUVs. Expect reduced urgency around EV capex and battery capacity expansion plans, with knock-on effects for battery cell makers, materials suppliers and charging network operators dependent on EV volume growth. Markets are likely to reprice EV-focused names lower relative to diversified ICE/EV hybrids in the near term. The move also reduces regulatory tailwinds for domestic battery supply chain investment tied to EV mandates. Longer term, the policy could slow U.S. EV market share growth relative to China and Europe, altering competitive dynamics in global auto and battery markets.
The Semi's shift from pilot-line hand-builds to true volume manufacturing removes the biggest credibility risk overhanging Tesla's trucking ambitions and gives it a first-mover position in electrified Class 8 freight just as diesel prices hit record highs above $6.50/gallon. Named commitments from PepsiCo, DHL, US Foods, ABF Freight and a 2,500-truck California coalition order signal that large logistics operators are willing to commit capital to electrification, pressuring incumbent diesel OEMs like Daimler Truck, PACCAR and Volvo to accelerate their own battery-electric heavy-truck programs. The Megacharger buildout (30+ stations, 200MW+ posts by year-end) also expands Tesla's charging business into heavy-duty applications, a new revenue and infrastructure moat beyond passenger vehicles. Use of in-house 4680 cells at scale, rather than purchased 2170s, tightens Tesla's vertical integration and could improve battery-cell unit economics as volumes ramp. Execution risk remains high given the truck's history of multi-year delays, but successful fulfillment of orders from operators like Einride and IMC Logistics would validate electric trucking's total-cost-of-ownership case against volatile diesel pricing.
GM's domestic sodium-ion push, backed by a $900M Warren battery campus investment, positions it as a politically favored automaker under the Trump administration's China-decoupling agenda, potentially easing regulatory risk relative to rivals. Ford faces reputational and possible regulatory headwinds from its CATL licensing deal, which could pressure its EV and ESS battery cost structure if political scrutiny escalates into policy action. Peak Energy stands to benefit from its exclusive-style partnership with GM, gaining a credible OEM validation for sodium-ion technology aimed at grid storage and data-center backup power. Longer term, success in sodium-ion could reduce U.S. demand for Chinese-controlled lithium, cathode and anode materials, reshaping competitive dynamics in battery materials and LFP supply chains. The commercial timeline (2029) means near-term financial impact is limited, but the policy signal increases investment risk premiums for any automaker with unresolved Chinese battery technology dependencies.
The episode shows the Trump administration using public pressure over China supply-chain ties to extract domestic manufacturing commitments from major automakers, a tactic likely to be replayed with other OEMs. Ford's response defuses immediate political risk and reinforces its narrative as the top U.S.-producing automaker, but it also signals that Chinese-linked battery and component sourcing (e.g., CATL-licensed technology) remains a political liability. Investors should watch for similar scrutiny directed at GM, Stellantis, and battery suppliers with Chinese technology partnerships, which could accelerate reshoring capital expenditure across the sector. The $1 billion is incremental to Ford's roughly $4 billion in prior Kentucky investment, supporting truck and SUV output rather than EVs, limiting direct relevance to EV-specific themes. Longer term, this dynamic could pressure the broader auto supply chain to diversify battery materials and components away from Chinese partners, benefiting non-Chinese battery and critical-minerals suppliers.
California's new rebate program is a durable demand-side subsidy that reshapes the competitive landscape for EV sales in the largest US auto market. The price-cap exemption for Rivian and Lucid gives these manufacturers a structural sales advantage over competitors whose vehicles are disqualified by the cap, potentially accelerating their volume recovery. Chinese EV makers and Tesla models above the price threshold are structurally disadvantaged in the California market relative to exempt manufacturers. The program also reinforces California's role as the primary driver of US EV adoption policy, with potential spillover to other states that follow California's regulatory lead. Battery and charging infrastructure suppliers benefit from the incremental demand stimulus.
