With no material revenue and largely experimental technology, picking a leader in glass batteries is difficult. Still, QuantumScape (NYSE:QS) has attracted more investor attention than any pure-play competitor.

The company went public via a SPAC merger in late 2020 and has since retrenched after an early surge in valuation during the EV boom. QuantumScape has demonstrated fast-charging single-layer cells and multi-layer prototypes, but scaling those results into full batteries remains a major challenge. As of mid-2026, the company had shipped QSE-5 cells to select automotive, defense and consumer electronics customers for testing.

It completed the installation of its Eagle Line, a highly automated pilot production line that will help it ramp QSE-5 cell production, which it was ramping up as of the second quarter.

QSE-5 is QuantumScape’s lead commercial candidate, a 24-layer automotive cell, and B1 samples now being tested. Momentum for the company improved in 2025 after the technology was demonstrated in an all-electric Ducati motorcycle, and QuantumScape signed a key materials partnership with Corning.

Most importantly, QuantumScape has a licensing agreement with Volkswagen’s PowerCo, which could mass-produce its battery designs once technical milestones are met, potentially supplying up to 1 million vehicles per year. It also recently announced a partnership with Honda to develop solid-state batteries together, and it's partnering with two other top-10 automakers, showing it's being embraced by major automakers.

The company has not yet recorded any revenue, but it has begun billing customers, so revenue could be recorded soon. QuantumScape ended Q2 2026 with nearly $1 billion in cash and marketable securities, giving it a funding runway through 2029.

Most major car manufacturers want to partner with battery tech start-ups working to build quantum glass batteries. Toyota (TM -0.49%) is taking a different route by looking to build its own. The company has been a laggard in the EV race, but in 2021, it said it would invest $13.6 billion in batteries over the next decade, including a significant portion in quantum glass batteries.

First, it's well capitalized with a thriving core business. There's no reason to worry about the glass battery investments sinking the stock, meaning it will be less volatile than a pure-play battery stock. Toyota also plans to initially use its solid-state battery cells in its hybrid vehicles.

In September 2022, the company acknowledged that it would take longer than expected to develop glass batteries for fully electric cars. Investors should expect such setbacks since producing these batteries at scale is a monumental engineering challenge.

At its June 2023 shareholders meeting, the company touted a "technological breakthrough" in its solid-state batteries and now aims to begin selling them by 2028, pushing back an earlier target date of 2025. It's now aiming for mass production by 2030, and it expects to focus on hybrids rather than EVs since the company sees hybrids as a good technological test case.

It said its first solid-state battery would offer a 20% increase in range over its standard lithium-ion battery to more than 600 miles and a fast charging time of 10 minutes or less.

In October 2025, it announced a development agreement with Sumimoto Metal Mining to mass-produce cathode materials for solid-state batteries, showing it's making progress, and the following month it opened its first battery plant in North America, though the plant is focused on high-performance lithium-ion batteries.

It's still on track to begin mass production on its solid-state battery by 2027 or 2028.

Solid Power (SLDP -3.83%) is another glass battery stock that went public through a SPAC. Unlike QuantumScape, which is focused on making a complete battery, Solid Power's initial aim is to make only the solid electrolyte component. The component would replace the liquid electrolyte that is part of lithium-ion batteries, which will help give them more range and decrease pack size.

Over the long term, the company plans to make its solid electrolyte more adaptable by removing nickel and cobalt from the cathode, which will help lower costs. Solid Power is now earning minimal revenue, bringing in $2.8 million in the first have of 2026.

The company had $419 million in total liquidity as of June 30, 2026, and has been developing its technology since its founding in 2012. Solid Power has an impressive list of high-profile investors, including carmakers such as Ford (F -0.85%), Hyundai (OTC:HYMTF), and BMW (BAMXF +0.81%), as well as electronics giant Samsung (SSNL.F +0.00%).

The company began producing automotive-scale battery cells in 2025 with partners like Ford, BMW, and SK On, a Korean energy company, and has been working on a BMW i7 powered by its cells.

Still, the company's market cap of less than $1 billion indicates investors are less convinced by Solid Power's technology than QuantumScape's, valued at roughly $4 billion.

Volkswagen (VWAGY -0.12%) has made a broad range of efforts to develop a battery cell, including its subsidiary, PowerCo, which recently unveiled a new unified battery cell.

It's working on both traditional lithium-ion batteries and solid-state batteries. Solid-state batteries are further behind in the company's pipeline than other battery chemistries like nickel manganese cobalt, lithium iron phosphate, and sodium-ion, which are easier to develop.

While solid-state technology isn't expected to enter production for at least a few years, the Ducati motorcycle powered with solid-state tech was a win for VW as well.

Moving ahead, its partnership with QuantumScape should provide it with an advantage, especially if the companies can deliver the new technology on schedule.

Volkswagen is aiming for mass production of these solid-state batteries by 2030.

General Motors (GM -0.78%) has also been taking something of an "all of the above" approach with electric vehicles. In addition to traditional lithium-ion batteries, the company is also experimenting with sodium-ion, lithium manganese-rich (LMR), and solid-state batteries.

GM is now the largest producer of battery cells in North America, in tandem with its top supplier, LG Energy Solution, and the company believes its cells cost less to produce than its rivals'.

The automaker has its battery development center, the Wallace Battery Cell Innovation Center, which opened in 2022, and like VW, it's experimenting with several different chemistries. Thus far, GM doesn't seem to have taken any significant steps in solid-state cells beyond research, but the company is spending aggressively on EVs and battery technology, so it should play a role in it in the future.

For the time being, GM is more focused on LMR technologies than producing solid-state cells.

Benefits and risks of investing in quantum glass battery stocks

Like any stock market sector, there are benefits and risks with quantum glass battery stocks. Here are some of the big ones to be aware of.

Benefits of quantum glass battery stocks:

The technology has a ton of upside potential as the addressable market is potentially every vehicle in the world, as well as other machines that could run on these batteries. If the technology fulfills its promise, there will be some big winners.
The pure-play glass battery stocks are still small, so the stocks have multi-bagging potential if they can demonstrate technological progress.
Glass battery stocks could make attractive acquisition targets for larger automakers and others looking to capitalize on this emerging technology.

Risks of quantum glass battery stocks:

At this point, glass battery stocks are speculative, and some of the pure-plays could go to zero if the technology does not live up to expectations.
Pure-play glass battery stocks are barely making any revenue, let alone profits.
These companies might be burning cash for several years, making future cash raises necessary.
A more efficient battery technology could emerge, disrupting the industry.
The technology may not live up to expectations.
The battery stocks that are available today might lose to competitors that aren't on the radar yet.

Methodology: How these stocks were chosen

The quantum glass industry is a niche industry, and there are only two pure-play stocks as of 2026, Quantumscape and Solid Power. The technology still hasn't reached commercialization and progress has been slow thus far.

Beyond those two stocks, the automakers that are doing the most on solid-state batteries are Toyota, Volkswagen, and General Motors. Still, investors are best off buying one of the two pure-play stocks if they truly want exposure to glass battery stocks.

Loading paragraph...

Should you invest in quantum glass battery stocks?

Investing in quantum glass battery stocks at this point is not much different from buying development-stage biotech stocks. We are still several years away from this technology going mainstream, and the field is wide open with no viable products available yet.

Additionally, promises of technology haven't always come true in the auto industry. Many industry insiders, including auto company CEOs, expected autonomous vehicles to be commonplace by now, but that hasn't happened.

That doesn't mean quantum batteries won't be successful, but investors may want to wait until more conclusive data comes in and a clear leader emerges. At this point, glass battery stocks are only suitable for investors with a very high tolerance for risk.
