None of them sells solid-state EV batteries at commercial scale yet, so all four are early-stage, high-risk bets on a technology the International Energy Agency (IEA) says still needs to be &#8220;demonstrated at scale.&#8221; The battery companies that already earn real revenue, such as Tesla&#8217;s energy storage business, lithium producer Albemarle and storage integrator Fluence, are a different and more established kind of battery stock.<\/p>\n<p>That split is the most useful thing to understand before reading any &#8220;top battery stocks&#8221; list. Solid-state names trade on milestones, partnerships and cash runway. Revenue-stage battery stocks trade on lithium prices, factory output and order backlogs. Mixing the two in one basket without knowing which is which is how investors end up surprised.<\/p>\n<p>This guide is written for <strong>US readers<\/strong>. It is general education, <strong>not personalized investment advice<\/strong>, and not a recommendation to buy or sell any security. Company figures below come from filings and official releases with the dates shown; they change every quarter, so check the latest filing before acting on any of them.<\/p>\n<h2>Battery stocks at a glance: five buckets<\/h2>\n<p>Most battery stock lists throw very different businesses together. Sorting them first makes the rest of the research easier.<\/p>\n<ul>\n<li><strong>Pure-play solid-state developers (US-listed):<\/strong> QuantumScape (QS), Solid Power (SLDP) and Factorial Energy (FAC). They are mostly pre-revenue and valued on technical milestones, automaker partnerships and how long their cash lasts.<\/li>\n<li><strong>Pivoted next-generation battery company:<\/strong> SES AI (SES). It started out developing lithium-metal EV cells and now focuses on energy storage systems, drone batteries and AI software for discovering battery materials.<\/li>\n<li><strong>Large battery makers and automakers with solid-state roadmaps:<\/strong> Toyota (NYSE-listed ADR: TM), Samsung SDI, LG Energy Solution, CATL, BYD and Panasonic. For them, solid-state is one research program inside a very large existing business, and most of their shares trade outside the US.<\/li>\n<li><strong>Battery stocks with revenue today:<\/strong> Tesla (TSLA) through its energy storage segment, Albemarle (ALB) in lithium, Lithium Americas (LAC) and Elevra Lithium (ELVR) in North American lithium supply, and Fluence Energy (FLNC) in grid-scale storage.<\/li>\n<li><strong>Battery and lithium ETFs:<\/strong> Global X Lithium &amp; Battery Tech ETF (LIT) and Amplify Lithium &amp; Battery Technology ETF (BATT). They are broad baskets of miners, cell makers and automakers, not solid-state pure plays.<\/li>\n<\/ul>\n<p>If the main interest is EV makers rather than the battery supply chain, BearSavings covers those separately in <a href=\"https:\/\/www.bearsavings.com\/blog\/top-ev-stocks-to-buy\/\">Top EV Stocks to Buy<\/a>. For how batteries fit into wider sector themes, see <a href=\"https:\/\/www.bearsavings.com\/blog\/top-sectors-to-invest-in-for-2026\/\">Best Sectors to Invest in for 2026<\/a> and <a href=\"https:\/\/www.bearsavings.com\/blog\/top-10-sectors-to-invest\/\">Top 10 Sectors to Invest in Over the Next 10 Years<\/a>.<\/p>\n<h2>What &#8220;solid-state battery&#8221; actually means (and why headlines blur it)<\/h2>\n<p>A conventional lithium-ion battery moves lithium ions through a <strong>liquid electrolyte<\/strong>: a solution of flammable organic solvents and a lithium salt. A solid-state battery replaces some or all of that liquid with a <strong>solid electrolyte<\/strong>. The promise is higher energy density (more range per pound), faster charging and better safety, because a solid electrolyte is harder to set on fire.<\/p>\n<p>The catch is that &#8220;solid-state&#8221; covers several quite different designs. The IEA&#8217;s Global EV Outlook 2026 groups them roughly like this:<\/p>\n<ul>\n<li><strong>Semi-solid-state:<\/strong> Already commercial. Uses a solid polymer electrolyte that has to run warm (around 60&#8211;90 &#176;C), where the polymer turns soft and rubbery.<\/li>\n<li><strong>Almost-solid-state:<\/strong> A rigid solid electrolyte with a small amount of liquid electrolyte added on the cathode side to improve conductivity. Prototype stage.<\/li>\n<li><strong>All-solid-state:<\/strong> Fully solid electrolyte. Being made at small scale for testing, but harder and costlier to manufacture than lithium-ion, and packs often need extra pressure to work.<\/li>\n<\/ul>\n<p>Why this matters for investors:<\/p>\n<ul>\n<li><strong>Headlines rarely say which type they mean.<\/strong> A &#8220;solid-state battery car&#8221; announcement can describe a semi-solid design that is already commercial or an all-solid-state prototype that is years from production.<\/li>\n<li><strong>The big safety and range gains come from the almost- and all-solid-state designs,<\/strong> which, per the IEA, are still at the prototype stage.<\/li>\n<li><strong>Cost comes first, then scale.<\/strong> The IEA expects solid-state batteries to stay mostly in premium vehicles until the first half of the 2030s, with early demand also coming from robots, drones and other high-value devices.<\/li>\n<\/ul>\n<p>So when a company says it is &#8220;leading in solid-state,&#8221; the right follow-up questions are: which design, at what production scale, for which customer, and on what date.<\/p>\n<h2>Solid-state battery timelines: who is targeting what (as of October 2026)<\/h2>\n<p>These are company targets and reported plans, not guarantees. Solid-state dates have slipped before: Electrek notes Toyota once aimed for 2020, then 2023, then 2026, before its current window.<\/p>\n<ul>\n<li><strong>Toyota:<\/strong> Targets a market launch of battery-electric vehicles with all-solid-state batteries in <strong>2027&#8211;28<\/strong>. In October 2025 it signed a joint development agreement with Sumitomo Metal Mining to mass-produce a &#8220;highly durable&#8221; cathode material, and partner Idemitsu Kosan began building a large pilot plant for solid electrolytes in January 2026, aiming to finish it in 2027.<\/li>\n<li><strong>Samsung SDI:<\/strong> Says it is preparing mass production of its &#8220;Solid Stack&#8221; all-solid-state batteries in the <strong>second half of 2027<\/strong>, &#8220;as originally planned,&#8221; and that humanoid robots will likely be the first commercial use, with EVs to follow (Q2 2026 earnings call, July 2026). In October 2025 it partnered with BMW and Solid Power to test solid-state cells in BMW vehicles.<\/li>\n<li><strong>CATL:<\/strong> Plans <strong>small-batch pilot production in 2027<\/strong>, per its July 2026 reply to investors. Chairman Robin Zeng has put CATL&#8217;s solid-state technology at stage 4 of 9 on the technology-readiness scale and said sulfide-based cells cost three to five times more than conventional lithium-ion. In September 2026, CATL&#8217;s chief manufacturing officer reportedly said large-scale commercialization is at least five years away.<\/li>\n<li><strong>BYD:<\/strong> Has committed to trial production in 2027. The IEA says BYD plans to sell its first EV with all-solid-state batteries from 2027 and begin mass production from 2030.<\/li>\n<li><strong>LG Energy Solution:<\/strong> Its official R&amp;D roadmap lists all-solid-state battery commercialization as <strong>planned for 2029<\/strong>, starting with premium high-performance EVs.<\/li>\n<li><strong>QuantumScape with Volkswagen&#8217;s PowerCo:<\/strong> The next phase is field testing of cells from QuantumScape&#8217;s new pilot line. A July 2026 amendment tied PowerCo&#8217;s payments to milestones over the next two years.<\/li>\n<li><strong>Factorial Energy:<\/strong> Expects its <strong>first commercial revenue in 2027<\/strong>, driven by a drone battery order and a supercar battery order, with fabrication capacity expanding in phases through 2028.<\/li>\n<\/ul>\n<p><strong>The pattern:<\/strong> robots, drones, defense and supercars come first; mass-market EVs come later, probably around 2030 or after. An investor buying a solid-state stock in 2026 is mostly buying the chance that this sequence goes to plan, which can take years to show up in revenue.<\/p>\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.bearsavings.com\/blog\/wp-content\/uploads\/2026\/10\/battery-stocks-winding-road-sunrise.jpg?v=1\" alt=\"Empty two-lane road curving into fog at sunrise, symbolizing the long road to solid-state battery commercialization\"\/><figcaption>A foggy road bending out of sight at sunrise: most solid-state targets sit in 2027&#8211;2030, with robots, drones and premium cars first in line.<\/figcaption><\/figure>\n<h2>US-listed solid-state battery stocks: what each company actually does<\/h2>\n<p>These are the names that dominate searches for &#8220;solid-state battery stocks&#8221; and &#8220;solid-state battery companies to invest in.&#8221; All four lose money today, and each one depends on a handful of partners.<\/p>\n<h3>QuantumScape (QS)<\/h3>\n<ul>\n<li><strong>What it is:<\/strong> A San Jose company developing solid-state lithium-metal cells built around a proprietary ceramic separator and an &#8220;anode-free&#8221; design. Its plan is to <strong>license<\/strong> the technology to partners that build factories at gigawatt-hour scale, rather than mass-producing cells itself.<\/li>\n<li><strong>2026 milestones:<\/strong> QuantumScape opened its <strong>Eagle Line<\/strong> pilot production line on February 4, 2026, using its &#8220;Cobra&#8221; separator process. In its Q2 2026 shareholder letter (July 22, 2026) it said core tools were running above 90% uptime, it was shipping samples to customers, and it aimed to double cell output again in the second half of 2026.<\/li>\n<li><strong>Partners:<\/strong> A multi-year partnership with <strong>Honda<\/strong> announced June 18, 2026; Volkswagen Group&#8217;s PowerCo; and two other top-10 automakers under joint development agreements. That is four top-10 automaker customers in total. It has also set up business units for AI data centers and aerospace\/defense, and says it shipped QSE-5 cells to a major American defense contractor.<\/li>\n<li><strong>The PowerCo deal, in numbers:<\/strong> Under a July 16, 2026 amendment (filed in an 8-K), the maximum PowerCo will pay QuantumScape for the program is <strong>$75.4 million, including amounts already paid<\/strong>, now tied to milestones such as delivering and validating cells.<\/li>\n<li><strong>Money:<\/strong> Q2 2026 GAAP net loss was $98.2 million. Liquidity was <strong>$859.0 million<\/strong> at the end of Q2, and full-year 2026 guidance is an adjusted EBITDA loss of $250&#8211;275 million.<\/li>\n<li><strong>What to watch:<\/strong> Field-test feedback from PowerCo, any licensing agreement with a factory build-out attached, and the Q3 2026 shareholder letter.<\/li>\n<li><strong>Key risks:<\/strong> No commercial-scale revenue, a business model that relies on partners&#8217; factories, and possible dilution if it raises more capital.<\/li>\n<\/ul>\n<h3>Solid Power (SLDP)<\/h3>\n<ul>\n<li><strong>What it is:<\/strong> A Colorado company that has moved to focus on making <strong>sulfide-based solid electrolyte<\/strong>, a key material for all-solid-state cells, rather than building cells at scale itself.<\/li>\n<li><strong>Partners:<\/strong> A Joint Evaluation Agreement with <strong>Samsung SDI and BMW<\/strong>, plus earlier work with SK On, which now includes a completed line-installation agreement and talks on a new collaboration deal. The first phase of the Samsung SDI\/BMW agreement expired on September 30, 2026. In August, management said it expected to keep working with both companies, with talks on later phases still under way; as of October 9, 2026, Solid Power had not announced an extension or a follow-on agreement.<\/li>\n<li><strong>2026 milestones:<\/strong> A continuous electrolyte manufacturing pilot line, with plant validation and startup planned for Q4 2026; talks with partners about a possible joint venture for commercial-scale electrolyte production in South Korea; and ISO 9001 certification in progress.<\/li>\n<li><strong>Money:<\/strong> Q2 2026 revenue and grant income was <strong>negative $0.3 million<\/strong> after a $1.2 million reversal of earlier revenue, and the net loss was $23.8 million. Total liquidity was <strong>$419.3 million<\/strong> with <strong>no debt<\/strong> as of June 30, 2026.<\/li>\n<li><strong>Key risks:<\/strong> Very small revenue, reliance on a few large partners, and the question of whether evaluation agreements turn into paid supply contracts.<\/li>\n<\/ul>\n<h3>Factorial Energy (FAC)<\/h3>\n<ul>\n<li><strong>What it is:<\/strong> A Massachusetts solid-state battery developer with two platforms. <strong>FEST<\/strong> targets high-power uses and, the company says, works with up to 80% of existing lithium-ion manufacturing equipment. <strong>Solstice<\/strong> is its high-energy all-solid-state platform for uses such as robotics and space.<\/li>\n<li><strong>Listing:<\/strong> Factorial merged with the SPAC Cartesian Growth Corporation III on <strong>June 5, 2026<\/strong>. Its shares trade on Nasdaq as <strong>FAC<\/strong> and its warrants as FACWW (exercise price $11.50).<\/li>\n<li><strong>Milestones:<\/strong> Factorial says Mercedes-Benz road testing of its cells in a lightly modified test vehicle went more than 1,200 km on one charge. Stellantis validated its 77 Ah cells and began road-testing them in a <strong>Dodge Charger Daytona<\/strong> development vehicle in June 2026. Mercedes-Benz, Stellantis, Hyundai and Kia are strategic backers.<\/li>\n<li><strong>Money:<\/strong> About <strong>$112.8 million<\/strong> in cash and cash equivalents at June 30, 2026, with full-year 2026 guidance of roughly $40 million in non-GAAP operating expenses and about $13 million in capex.<\/li>\n<li><strong>Key risks:<\/strong> A newly de-SPACed stock, a type that has historically been volatile; outstanding warrants; and a gap between demonstration vehicles and paid automotive volume.<\/li>\n<\/ul>\n<h3>SES AI (SES)<\/h3>\n<ul>\n<li><strong>Why it shows up in solid-state searches:<\/strong> SES started out developing lithium-metal EV batteries, and older lists still call it a solid-state play. In August 2026, though, the company said it had &#8220;pivoted more than a year ago&#8221; to <strong>energy storage systems (ESS) and drone batteries<\/strong>, plus an AI platform for discovering materials called Molecular Universe.<\/li>\n<li><strong>What changed:<\/strong> It bought China-based storage maker <strong>UZ Energy<\/strong> (deal closed September 15, 2025). ESS is now its largest revenue source.<\/li>\n<li><strong>Numbers:<\/strong> Q2 2026 revenue was <strong>$5.1 million<\/strong>, up from $3.5 million a year earlier. Liquidity was about $163 million, and full-year 2026 revenue guidance is <strong>$30&#8211;35 million<\/strong>.<\/li>\n<li><strong>Key risks:<\/strong> A small revenue base, a business in the middle of changing direction, and supply-chain and policy exposure through its China-based subsidiary.<\/li>\n<\/ul>\n<p>For a broader look at how to judge young, story-driven growth stocks, see <a href=\"https:\/\/www.bearsavings.com\/blog\/how-to-spot-multibaggers-early\/\">How to Spot Multibaggers Early<\/a>, and for the downside of that approach, <a href=\"https:\/\/www.bearsavings.com\/blog\/lessons-i-learned-as-a-growth-investor-after-losing-30000-on-a-single-stock\/\">Lessons I Learned as a Growth Investor After Losing $30,000 on a Single Stock<\/a>.<\/p>\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.bearsavings.com\/blog\/wp-content\/uploads\/2026\/10\/battery-stocks-salt-evaporation-ponds.jpg?v=1\" alt=\"Aerial view of pink salt evaporation ponds edged with white salt crust\"\/><figcaption>Salt evaporation ponds from above: lithium brine producers use similar ponds, and their profits swing with lithium prices.<\/figcaption><\/figure>\n<h2>The big battery makers: solid-state is one bet among many<\/h2>\n<p>The companies with the most manufacturing muscle are mostly listed outside the US, and solid-state is a small part of what drives their shares.<\/p>\n<ul>\n<li><strong>Toyota (ADR: TM on the NYSE):<\/strong> The world&#8217;s largest automaker by sales. Its solid-state program matters for the long term, but the stock moves mostly with car volumes, hybrids and currency.<\/li>\n<li><strong>Samsung SDI and LG Energy Solution:<\/strong> Both are listed in Korea. US investors usually own them through international funds or ETFs (both sit among LIT&#8217;s largest holdings) or through brokers that offer Korean market access.<\/li>\n<li><strong>CATL:<\/strong> The world&#8217;s largest battery maker. Its A-shares trade in Shenzhen, and it listed H-shares in <strong>Hong Kong (3750) on May 20, 2025<\/strong>; Reuters reported that US onshore investors were excluded from that offering. CATL is on the Pentagon&#8217;s <strong>Section 1260H &#8220;Chinese military companies&#8221; list<\/strong> (June 2026 update, alongside BYD, EVE Energy and CALB). That designation does not by itself ban US investors from buying the shares, but it adds policy and supply-chain risk. CATL also mass-produces <strong>Naxtra sodium-ion batteries<\/strong>, with Changan&#8217;s first sodium-ion passenger car due to reach the market by mid-2026.<\/li>\n<li><strong>Panasonic:<\/strong> Tesla&#8217;s long-time cell partner. Its De Soto, Kansas plant was running at about half capacity making 2170-format EV cells as of June 2026, while 4680 production has been delayed repeatedly and some lines may move toward data-center batteries.<\/li>\n<\/ul>\n<h2>Battery stocks with revenue today<\/h2>\n<p>These names do not depend on solid-state succeeding. They depend on EV demand, grid storage demand and lithium prices.<\/p>\n<h3>Tesla (TSLA)<\/h3>\n<ul>\n<li><strong>Battery angle:<\/strong> Megapack and Powerwall energy storage. Tesla <strong>deployed 13.7 GWh of energy storage in Q3 2026<\/strong> while delivering 486,532 vehicles (8-K, October 2, 2026). Q3 financial results are due October 21, 2026.<\/li>\n<li><strong>Reality check:<\/strong> Storage is growing, but TSLA is still mostly a bet on cars, autonomy and robotics. Model scenarios with the <a href=\"https:\/\/www.bearsavings.com\/tools\/tesla-stock-calculator\/\">Tesla stock calculator<\/a> rather than assuming storage alone drives returns.<\/li>\n<\/ul>\n<h3>Albemarle (ALB)<\/h3>\n<ul>\n<li><strong>Battery angle:<\/strong> One of the largest lithium producers in the world.<\/li>\n<li><strong>Q2 2026:<\/strong> Net sales of $1.7 billion (up 31%) and adjusted EBITDA of $858 million (up 155%). Average realized lithium price was <strong>$19.53\/kg LCE, against $12.17 a year earlier<\/strong>. Full-year Energy Storage sales volume guidance is 225&#8211;235 kt LCE, partly reduced by a June 9 fire at the Talison CGP3 plant.<\/li>\n<li><strong>Lesson:<\/strong> ALB is a commodity-cycle stock. The IEA notes that lithium prices in early 2026 were more than double a year earlier but still around 70% below their 2022 peak.<\/li>\n<\/ul>\n<h3>Lithium Americas (LAC)<\/h3>\n<ul>\n<li><strong>Correction to older lists:<\/strong> Lithium Americas split in October 2023. The Argentina business went to a separate company (now Lithium Argentina), so today&#8217;s LAC is about <strong>Thacker Pass in Nevada<\/strong>.<\/li>\n<li><strong>Status (Q2 2026 report, August 13, 2026):<\/strong> Phase 1 is designed for 40,000 tonnes a year of battery-quality lithium carbonate, with mechanical completion targeted for <strong>late 2027<\/strong>. The joint venture is 62% LAC and 38% General Motors. The DOE loan is $2.23 billion, with $1.209 billion advanced so far, and the DOE holds warrants for about a 5% equity stake in LAC.<\/li>\n<li><strong>Dilution in action:<\/strong> LAC sold 13.0 million shares at an average of $5.36 under an at-the-market program, then 1.1 million more at $3.87 after the quarter, and agreed to issue $150 million of convertible debentures in August 2026.<\/li>\n<\/ul>\n<h3>Elevra Lithium (ELVR), formerly Piedmont Lithium<\/h3>\n<ul>\n<li><strong>Correction to older lists:<\/strong> Piedmont Lithium (PLL) merged with Sayona Mining in late August 2025 to form <strong>Elevra Lithium<\/strong>, which trades on Nasdaq as ELVR (ADS) and on the ASX as ELV. Elevra has also agreed to sell its interest in the Ewoyaa project in Ghana.<\/li>\n<li><strong>June 2026 quarter:<\/strong> North American Lithium in Quebec produced 54,479 dry tonnes of spodumene concentrate.

The most-followed US-listed pure plays are QuantumScape (QS), Solid Power (SLDP) and Factorial Energy (FAC), with SES AI (SES) often included even though it has pivoted to storage and drones. All four are pre-commercial or very early in revenue, so many investors treat them as small speculative positions next to established battery stocks or ETFs.<\/p>\n<h3>Which company is leading in solid-state batteries?<\/h3>\n<p>There is no clear winner yet. Toyota (2027&#8211;28), Samsung SDI (second half of 2027, robots first), CATL and BYD (pilot or trial production in 2027) and LG Energy Solution (2029) have the most manufacturing scale. QuantumScape and Factorial have the most-watched US road tests and pilot lines.<\/p>\n<h3>When will solid-state batteries be in cars?<\/h3>\n<p>The first small runs are targeted for 2027&#8211;28 (Toyota, BYD), but the IEA expects solid-state to stay mostly in premium vehicles until the first half of the 2030s.<\/p>\n<h3>Is there a solid-state battery ETF?<\/h3>\n<p>No US-listed solid-state-only ETF was found as of this update. LIT (0.75%) and BATT (0.59%) are broad lithium and battery baskets, and LIT&#8217;s September 25, 2026 holdings did not include QS, SLDP, FAC or SES.<\/p>\n<h3>Is QuantumScape a good stock to buy?<\/h3>\n<p>That depends on goals and risk tolerance. QuantumScape has $859.0 million of liquidity, four top-10 automaker customers and a working pilot line, but no commercial-scale revenue, a licensing model that depends on partners, and ongoing losses.<\/p>\n<h3>How can US investors buy CATL stock?<\/h3>\n<p>Through a broker with Hong Kong (3750) or mainland China market access, or indirectly through funds that hold it, such as LIT. Note its Section 1260H listing.<\/p>\n<h3>Are sodium-ion battery stocks an alternative to solid-state?<\/h3>\n<p>Sodium-ion batteries are a separate, cheaper chemistry with no lithium. CATL already mass-produces its Naxtra sodium-ion cells, so sodium-ion is a nearer-term theme than solid-state, but most pure plays trade outside the US.<\/p>\n<h2>Bottom line<\/h2>\n<p>Solid-state battery stocks are a bet on timelines: QuantumScape, Solid Power and Factorial could matter a great deal if 2027&#8211;2030 production plans hold, and very little if they slip again. Battery stocks with revenue today, such as Tesla&#8217;s storage business, Albemarle, Lithium Americas, Elevra and Fluence, carry different risks: commodity cycles, factory ramps and financing. A broad core plus a small, deliberately sized battery satellite is one common way investors approach the theme.<\/p>\n<p><em>This article is for educational purposes only and is not investment, tax or legal advice.
