How to Invest in Electric vehicles and batteries

How does the EV and battery supply chain work?

An electric vehicle is built around its battery, so the EV and batteries theme spans a chain from raw materials to finished car. It starts with lithium and other battery metals, where ALB (Albemarle) is one of the largest lithium producers. Those materials go into battery cells, then into packs, then into vehicles designed around them. Automakers like TSLA, RIVN, LCID, and NIO sit at the end of that chain, and the cost and performance of the battery largely determine whether an EV is competitive on price and range.

This is why the EV and batteries theme groups automakers, materials suppliers, and battery-technology developers together rather than treating them as separate stories. The battery is roughly a third of an EV's cost, so anything that lowers battery cost or improves energy density, the focus of next-generation developers like QS (QuantumScape) and its solid-state approach, flows directly into the competitiveness of the whole theme. The supply chain framing is what ties materials, cells, and vehicles into one EV and batteries thesis.

Why is EV adoption a long-term theme but a volatile investment?

EV adoption is a durable, multi-decade trend: the share of new cars sold that are electric has risen steadily, driven by improving technology, falling battery costs, regulation, and expanding model choice. That secular direction is the bull case for the EV and batteries theme. The problem for investors is that the equity expression is far bumpier than the adoption curve, because building cars profitably at scale is brutally hard and capital-intensive.

Within the EV and batteries theme, this shows up as a wide gap between names. TSLA reached scale and profitability, while pure-play challengers like RIVN, LCID, and NIO have burned cash trying to ramp production and are sensitive to financing conditions. The segment also reacts sharply to interest rates (which affect car affordability and company funding), subsidies and tariffs, and price competition that can compress everyone's margins at once. So the EV and batteries theme pairs a real long-term shift with genuinely high equity volatility.

What is solid-state battery technology?

Most EVs today use lithium-ion batteries with a liquid electrolyte. Solid-state batteries replace that liquid with a solid material, which in principle allows higher energy density (more range in the same weight), faster charging, and improved safety. This next-generation technology is a key frontier of the EV and batteries theme because cheaper, denser, safer cells would directly improve EV competitiveness against gasoline cars. QS (QuantumScape) is among the most-watched public developers pursuing solid-state cells.

The important caveat within the EV and batteries theme is timing and risk. Solid-state developers like QS are largely pre-revenue and have not yet proven mass manufacturability, so they are speculative bets on a technical breakthrough rather than on current sales. They sit at the high-risk end of the EV and batteries theme, distinct from the established automakers and the cash-generating lithium suppliers, which is why a basket often sizes them small.

What gets a stock into the Electric vehicles and batteries theme?

Revenue or development exposure to electrified transport: electric-vehicle automakers, battery cell and pack makers, lithium and battery-materials suppliers, and next-generation battery-technology developers.

How to invest in Electric vehicles and batteries

There are a few ways to get exposure to the electric vehicles and batteries theme, and Walnut is not an investment adviser, so this is descriptive. The most concentrated path is buying individual stocks that fit the thesis, and the key decision is how much risk you want across a very uneven set. TSLA is the scaled, profitable leader; RIVN, LCID, and NIO are unprofitable pure-play challengers with higher upside and higher risk; ALB gives upstream lithium exposure; and QS is a speculative pre-revenue bet on solid-state technology. Choosing single names lets you tune that risk mix precisely, which matters more in the EV and batteries theme than in most because the names behave so differently. The passive route is broad innovation or sector funds: ARKK holds TSLA and other EV-related names but blends them into a wider disruptive-tech mandate, so the EV exposure is diluted. There is no pure-play EV-and-battery ETF in Walnut's valid proxy set as of early 2026.

The alternative is building a dedicated EV and batteries basket in Walnut. You describe the thesis to Walnut's AI assistant, for instance electric vehicles and batteries spanning automakers, lithium supply, and next-generation cells, and the assistant proposes constituents and starting weights drawn from names like TSLA, RIVN, LCID, NIO, ALB, and QS, with the rationale for each. You can deliberately balance the scaled leader against the speculative names, review and adjust every weight, and fund the basket through your own connected broker. You approve every order before it is placed; Walnut never trades for you. The EV and batteries basket then tracks as a single performance line.

Which ETFs cover Electric vehicles and batteries?

If you want the theme as a single ticker rather than as a basket, these are the ETFs people most commonly use. Each has trade-offs (concentration, expense ratio, sector overlap) covered in the individual ETF guides.

The bottom line on Electric vehicles and batteries

Electric vehicles and batteries is a real long-term shift expressed through a volatile and uneven equity set: a profitable scaled leader (TSLA), unprofitable challengers (RIVN, LCID, NIO), a lithium supplier (ALB), and a pre-revenue technology bet (QS). It fits a portfolio as a satellite tilt sized for volatility, and a focused basket lets you balance the scaled leader against the speculative names more deliberately than ARKK, where EV is one slice of a broad innovation fund.
