The company says the technology will be deployed in mainstream automobiles —*PopMech*'s reporting namechecked Audi and Volkswagen — as soon as 2024, bringing EV charging substantially closer to the convenience of filling up a gas tank. But the devil is in the details, with critics saying we shouldn't take those claims at face value. Just as with lithium-ion batteries, solid-state ones — QuantumScape's battery is entirely solid-state, meaning that it doesn't rely on the conventional mix of chemicals of a lithium-ion battery powering today's EVs — come with drawbacks as well. Proponents argue that solid-state batteries are safer and more stable than their lithium-ion counterparts, as they are less prone to [catching on fire](). They also can cram more energy into the same amount of space — on paper at least — while also allowing drivers to recharge their vehicles faster. During tests, some of QuantumScape's prototype batteries were able to discharge and charge almost 1,000 times. "Traditional lithium-ion cells, or any other solid-state effort to date, couldn’t even come close to that," chief marketing officer Asim Hussain told *PopMech*. But the technology has plenty of drawbacks as well. For one, producing these batteries at a mass-manufacturing scale is proving difficult, despite billions of dollars in investment by the likes of juggernaut carmakers Nissan and [Toyota](), *PopMech* reports. All told, not everybody is entirely convinced we're just two years away from reliable solid-state batteries powering almost every EV on the market. "There are challenges with how you translate energy density demonstrated in a research laboratory cell to a larger cell for practical applications," Yang Shao-Horn, who is working on battery efficiency tech at MIT’s Electrochemical Energy Lab, told the magazine. "There are physical limitations to energy density." Then there's the fact that solid-state batteries need to breathe and be able to expand. Controlling that pressure is already proving difficult in a lab. That also means chances of an explosion may also persist when moving away from lithium-ion batteries. "We are doubling the energy density which means that the energy is very high, just like a bomb for example," Nissan’s battery strategy group lead Yoshiaki Nitta told the publication. Automakers appear to be convinced that solid-state batteries are the future of the electric vehicle, promising longer ranges and faster recharge times. But the technology is still in its infancy, and plenty of work still needs to be done until we can finally ditch the lithium-ion battery altogether. **READ MORE:** [A Revolutionary Solid-State Battery Is Nearly Here, Scientists Say]() \[*Popular Mechanics*\] **More on solid state:** *[Toyota Making Electric Car With "Game-Changing" Solid State Battery]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
