The best battery stocks right now include Tesla, SQM, Albemarle, EnerSys, QuantumScape, Fluence Energy, and Enovix, chosen for their position across the battery supply chain, their balance sheets, and their exposure to grid storage demand. Demand is no longer just about electric cars. AI data centers, utility-scale grid storage, and backup power are all pulling on the same battery supply. Fluence Energy ended its most recent quarter with a record backlog near $5.6 billion, and Tesla booked more than 43 GWh of Megapack storage orders in a single six-week stretch. We screened the largest US-listed battery names and narrowed the field to seven, ordered here by market value.
How We Picked These Stocks
The battery world runs from the mines that pull lithium out of the ground to the labs designing cells that do not exist in mass production yet. We filtered for four things: a US listing, batteries or battery materials as a core business, enough size and trading volume to matter, and a clear role in the supply chain. We split the list on purpose. Four of these companies are profitable today and sell real products at scale. Three are earlier-stage bets on new technology, where the payoff depends on execution that has not happened yet. Every investor should know which bucket a stock sits in before buying.
The Best Battery Stocks Right Now
Tesla (NASDAQ: TSLA)
Why it made the list: Most people know Tesla for its cars, but it earns a spot here as the largest maker of battery cells and stationary storage in the West. Its Megapack, a shipping-container-sized battery for utilities, has become a business of its own, and Tesla builds the cells that go inside its vehicles and storage systems.
The bull case: Energy storage is Tesla's fastest-growing segment. It deployed roughly 46.7 GWh of storage in 2025, and recent deals like a 25 GWh Megapack agreement with NatPower across Italy and Britain point to years of demand from grids adding solar and wind.
The risk: The car business still drives most of the revenue and the stock price, so a slump in vehicle sales can overwhelm the storage growth story.
Key number: Tesla booked more than 43 GWh of new Megapack orders in a six-week span.
Sociedad Quimica y Minera (NYSE: SQM)
Why it made the list: SQM is one of the two companies that mine lithium from Chile's Salar de Atacama, the richest and lowest-cost lithium brine deposit on earth. Lithium is the core material in almost every battery sold today, so SQM sits at the very start of the chain.
The bull case: SQM is entering the year with record production volumes and a $2.7 billion expansion underway. If lithium prices keep recovering from their multi-year lows, its low mining costs turn into wide profit margins.
The risk: Lithium is a commodity, so SQM's earnings swing hard with the price. It also depends on its relationship with the Chilean government, which is taking a larger role in the country's lithium.
Key number: SQM is expanding lithium carbonate capacity toward 240,000 tonnes a year.
Albemarle (NYSE: ALB)
Why it made the list: Albemarle is the largest US-based lithium producer and SQM's partner in the Salar de Atacama. It supplies lithium to battery and automaker customers around the world and is a direct way to bet on rising battery demand. For a fuller look at the miners, see our guide to the best lithium stocks.
The bull case: Albemarle has spent the downturn cutting costs, targeting another $100 million to $150 million in savings this year, and filed for review of a $3.1 billion project using direct lithium extraction, a cheaper and faster way to pull lithium from brine.
The risk: The stock trades far below its old highs for a reason. A prolonged stretch of weak lithium prices would keep pressure on earnings.
Key number: Albemarle trades near $129, down sharply from a 52-week high above $220.
EnerSys (NYSE: ENS)
Why it made the list: EnerSys is the profitable, unglamorous anchor of this list. It makes industrial batteries for forklifts, telecom networks, defense equipment, and backup power, and it is pushing into lithium storage for data centers. It has trailing revenue near $3.74 billion and pays a dividend.
The bull case: EnerSys holds more than 50% of the US market for the lead-acid batteries data centers use for backup, and it is launching a new lithium system to defend that turf as AI power loads grow. Its defense battery backlog is climbing as military budgets rise.
The risk: The lithium data-center product is early, and management does not expect meaningful revenue from it until fiscal 2028.
Key number: Data center sales rose 28% in its most recent quarter.
QuantumScape (NYSE: QS)
Why it made the list: QuantumScape is developing a solid-state battery, one that replaces the liquid inside a normal lithium-ion cell with a solid material. The goal is a battery that holds more energy, charges faster, and is less likely to catch fire. It is the highest-profile name in next-generation battery technology.
The bull case: Its long partnership with Volkswagen's battery unit, PowerCo, includes milestone payments and a licensing deal, and its new COBRA manufacturing process is a real step toward building cells at scale. It shipped sample cells to Volkswagen for testing.
The risk: QuantumScape has no meaningful revenue and burns cash. Solid-state batteries have missed commercial timelines for years, and success is still not guaranteed.
Key number: PowerCo has committed up to $131 million in milestone payments tied to the pilot line.
Fluence Energy (NASDAQ: FLNC)
Why it made the list: Fluence Energy builds and services large battery systems that store power for the electric grid. When a utility needs to bank solar power for the evening or steady out its supply, Fluence provides the hardware and software to do it. It is a pure play on grid-scale storage.
The bull case: Fluence carries a record backlog near $5.6 billion, and its total project pipeline grew to roughly $31.5 billion, boosted by new deals to power AI data centers. Order intake doubled year over year.
The risk: Fluence has swung between profits and losses, and it competes directly with Tesla and low-cost overseas suppliers, which squeezes margins.
Key number: A record backlog near $5.6 billion, with the pipeline up about 35% this year.
Enovix (NASDAQ: ENVX)
Why it made the list: Enovix builds lithium batteries with a silicon anode, the part of the cell that stores the charge, in place of the usual graphite. Silicon can hold far more energy, which means longer battery life in phones, laptops, and eventually electric vehicles. It is the smallest name here.
The bull case: Enovix is moving from the lab into large-scale production and has lined up customers in consumer electronics, a market it can reach faster than the automotive one.
The risk: Like QuantumScape, Enovix is pre-profit and must prove it can manufacture at volume without the yield and quality problems that sink most new battery makers.
Key number: Enovix trades near $5, well below its 52-week high above $16.
Where the Battery Market Stands Now
The story has shifted. For a decade, batteries meant electric cars, and the stocks traded on EV sales. That link still matters, but two newer forces are now just as important. The first is the electric grid. As utilities add solar and wind, they need enormous batteries to store that power for when the sun sets and the wind drops, which is driving the record backlogs at Fluence and Tesla's Megapack unit. Our guide to the best energy stocks covers the broader power sector these storage systems plug into.
The second force is artificial intelligence. Data centers running AI models draw huge, sudden power loads, and operators are turning to batteries for backup and to smooth those spikes. That is why a lead-acid battery maker like EnerSys and a grid-storage firm like Fluence both now talk about data centers as a growth market. The same electricity crunch is lifting demand for nuclear power, the other side of the AI energy trade.
Underneath all of it sits lithium. Prices collapsed from their 2022 peak as supply caught up, punishing miners like SQM and Albemarle. Early signs of a price recovery, plus expansion projects timed for the next demand wave, are why the miners belong on any battery list even after a brutal stretch.
What to Watch
- Lithium prices: A sustained rebound would flow straight to SQM and Albemarle earnings. A renewed slump would do the opposite.
- Solid-state milestones: QuantumScape's B1 sample testing and any expansion of the Volkswagen deal are the key signposts for the next-generation names.
- Data center orders: Watch for new grid-storage and backup-power deals tied to AI, which would extend the backlogs at Fluence and EnerSys.
The Bottom Line
Batteries are no longer a single bet on electric cars. This list splits cleanly into two groups. Tesla, SQM, Albemarle, and EnerSys are established companies with real revenue and, in the miners' case, deep cyclical swings. QuantumScape, Fluence, and Enovix are higher-risk plays on grid storage and new cell technology, where the reward depends on execution still to come. Investors who want steadier exposure lean toward the profitable names, while those chasing the next breakthrough accept the volatility of the early-stage ones.
Frequently Asked Questions
What are the best battery stocks to buy?
The largest and most established US-listed battery stocks include Tesla, SQM, Albemarle, and EnerSys, which are profitable and sell products at scale today. QuantumScape, Fluence Energy, and Enovix are higher-risk names tied to grid storage and next-generation battery technology. A balanced approach often mixes a couple of profitable leaders with a small position in the earlier-stage bets.
Are battery stocks a good investment right now?
Battery demand is broadening beyond electric cars into grid storage and AI data centers, which is driving record order backlogs at companies like Fluence and Tesla's Megapack unit. That said, the sector is volatile: lithium prices have been weak, and several battery-technology companies are not yet profitable. The risk profile varies widely from one name to the next.
What is the difference between a lithium stock and a battery stock?
Lithium stocks like SQM and Albemarle mine and process the raw material that goes into batteries, so they rise and fall with the price of lithium. Battery stocks build the finished cells or systems, from Tesla's Megapack to QuantumScape's solid-state cells. The two are linked, but a lithium miner can struggle even when battery demand is strong if the metal's price is falling.
What is a solid-state battery?
A solid-state battery replaces the liquid electrolyte inside a normal lithium-ion cell with a solid material. In theory that allows more energy in the same space, faster charging, and a lower fire risk. QuantumScape is the best-known company chasing this technology, but no one yet produces solid-state cells at large commercial scale.
Why are AI data centers driving battery demand?
Data centers running AI models pull large, sudden bursts of power, and batteries help supply backup and smooth those spikes so the grid stays stable. That has turned data centers into a new customer base for battery makers, from EnerSys on the backup side to Fluence on grid-scale storage. It adds a source of demand that has nothing to do with electric cars.
