Almost everything we rely on during a normal day runs on stored electricity. Phones, laptops, cordless drills, electric toothbrushes, and increasingly the cars in our driveways all depend on a battery that has to be charged, degrades over time, and eventually needs replacing. Energy storage is one of the real bottlenecks of modern technology, and researchers have spent decades looking for a fundamentally better cell.
One of the most talked-about candidates is the quantum glass battery. It has been called the “forever battery” and the “holy grail” of energy storage, and headlines have linked it to Tesla, Samsung, and other household names. So who actually makes the quantum glass battery, what does it promise, and is it something you can buy today? Let’s go through it properly.
What Is the Quantum Glass Battery?
Before asking who makes it, it helps to understand what it is. The idea traces back to research published in 2017 by John B. Goodenough, the Nobel Prize-winning co-inventor of the lithium-ion battery, working with Maria Helena Braga of the University of Porto. Instead of the flammable liquid electrolyte used in conventional lithium-ion cells, their design uses a solid glass electrolyte that conducts ions through the material itself.
The “quantum” part of the name comes from the way charge moves through that glass at the atomic level rather than through a liquid. The practical appeal is simpler: a solid electrolyte is not flammable, tolerates a wider temperature range, and in the lab has shown far higher energy density than the cells in today’s phones and EVs. That combination is why the technology attracted so much attention so quickly.
Who Makes Quantum Glass Batteries?
The honest answer is that no single company “makes” a quantum glass battery you can order. The core research came from Goodenough’s team at the University of Texas at Austin and Braga’s group in Porto, and the underlying patents sit with those institutions and the researchers themselves. What exists today is a family of solid-state battery projects at large manufacturers, all chasing the same goal by slightly different routes.
Tesla is the name most people associate with it. Elon Musk has talked publicly about a “million-mile battery,” and Tesla’s battery research partnerships are widely understood to include solid-state work. But Tesla has never announced a glass-electrolyte product, and its shipping cars still use conventional lithium-ion cells.
Samsung SDI, Panasonic, Nissan, Toyota, and General Motors all run their own solid-state programs, and specialist firms such as QuantumScape and Solid Power exist purely to commercialise the concept. Toyota and Nissan have both put target dates on solid-state EVs in the second half of this decade. None of these companies uses the phrase “quantum glass battery” for their own product; it is a media label that has stuck to the whole category.
Quantum Glass Battery Stocks
Because of the hype, plenty of investors have gone looking for a “quantum glass battery stock.” Be careful here. There is no listed company whose business is the Goodenough glass battery. What you can invest in are the established manufacturers running solid-state programs and the pure-play solid-state start-ups.
Samsung
Samsung SDI is one of the largest battery makers in the world and supplies cells to several car brands. It has shown solid-state prototypes and has the manufacturing scale to industrialise a new chemistry if one proves out. For most investors it is the lowest-risk way to gain exposure to the technology, because the rest of Samsung’s business does not depend on it.
Panasonic
Panasonic has built batteries for more than a century and is Tesla’s longest-standing cell partner, with joint production at the Nevada Gigafactory. Its research on next-generation chemistries is well funded, and if a glass or solid-state cell reaches Tesla vehicles, Panasonic is a likely manufacturing partner.
Whatever you pick, treat it as a long-horizon position. The technology is still moving from laboratory to factory, and timelines in this industry slip regularly.
Is the Quantum Glass Battery Even Real?
Yes, but with an important caveat. The science is real and was published in a peer-reviewed journal; other researchers have questioned some of the original energy claims, and the debate over exactly how the cell works has never fully settled. What is not real yet is a mass-produced quantum glass battery in a car or a phone.
Today’s devices still use lithium-ion. It works, it is cheap at scale, and the supply chain is enormous, but it degrades with every charge cycle, is sensitive to heat and cold, and the liquid electrolyte can catch fire when damaged. Solid-state designs, including the glass battery, aim to fix all three problems at once. That is why the largest manufacturers keep spending on it even though the first products are still ahead of us.
Is a Quantum Glass Battery Any Good?
Think of this section as the closest thing to a quantum glass battery review that is currently possible. The reported advantages, based on the original research and the claims manufacturers have made about solid-state cells generally, include:
- Much longer life. Lab cells survived thousands of charge cycles with little capacity loss, which is why the “forever battery” nickname appeared.
- Faster charging. A solid electrolyte can, in principle, accept charge far more quickly than a liquid one without the plating problems that shorten lithium-ion life.
- More range per kilogram. Higher energy density means a lighter pack for the same range, or a longer range for the same weight.
- Safety. No flammable liquid means no thermal runaway of the kind behind most battery fires.
- Cold-weather performance. The glass electrolyte was shown working well below freezing, where lithium-ion cells lose a large share of their capacity.
If those characteristics carry over into production, the impact goes beyond cars. Smaller, safer batteries would allow slimmer portable electronics, more reliable home energy storage, and a faster shift away from fossil fuels for transport.
Conclusion
So, who makes the quantum glass battery? Nobody yet, at least not as a product. It began as university research by John Goodenough and Maria Helena Braga, and the race to turn it into something you can buy is being run by Tesla’s partners, Samsung, Panasonic, Toyota, Nissan, and a handful of solid-state specialists. The promise is a battery that lasts longer, charges faster, and does not burn. The reality is that we are still a few years from seeing one in a showroom, but every major manufacturer is betting that it is coming.
