Most investors probably aren't familiar with quantum glass batteries, but the technology could revolutionize electric vehicles (EVs) and the broader renewable energy industry. If you're wondering what a quantum glass battery is, a brief explanation follows.
What are quantum glass batteries?
Quantum glass batteries, or glass batteries, offer more advanced technology than the lithium-ion batteries common in today's EVs. In glass batteries, electrolytes have a higher energy density and can deliver an equal amount of power as lithium-ion batteries but in a smaller space.
Quantum glass batteries also don't catch fire, so they don't need the components that lithium-ion batteries have to prevent them from doing so. Quantum glass batteries charge faster, too, and their higher energy density means they can give EVs greater range.
Glass batteries are still a nascent technology, but you can see why this market would be alluring to investors, especially given the explosion in demand for EVs over the past few years and the general belief that EVs will eventually displace gas-powered vehicles.
Below, we'll explore some of the companies that hold critical patents in quantum glass batteries. Keep reading to learn more about three of the best quantum glass battery technology companies today.
Best quantum glass battery stocks in 2025
| Company name | Company ticker | Market cap | Industry |
|---|---|---|---|
| QuantumScape | NYSE:QS | $9.1 billion | Auto Components |
| Toyota Motor | NYSE:TM | $260.8 billion | Automobiles |
| Solid Power | NASDAQ:SLDP | $1.2 billion | Auto Components |
1. QuantumScape
NYSE: QS
Key Data Points
It's hard to pick a leader in an industry with no material revenue and still experimental technology. However, QuantumScape has received more investor attention than any other pure-play glass battery stock.
The company went public through a special purpose acquisition company (SPAC) merger with Kensington Capital Acquisition in late 2020. The stock has cooled off since its market cap jumped to more than $50 billion in December 2020, along with a broad boom in tech and EV stocks.
QuantumScape has revealed tests showing that its single-layer battery cells can charge to 80% capacity in fewer than 15 minutes and demonstrated the successful performance of 10-layer cells. However, building an entire fuel cell would take 100 of those single-layer battery cells, and a complete battery would take hundreds.
2. Toyota
NYSE: TM
Key Data Points
Most major car manufacturers want to partner with battery tech start-ups working to build quantum glass batteries. Toyota 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 2027-28, 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.
3. Solid Power
NASDAQ: SLDP

Are quantum glass battery stocks right for you?
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.
