Earlier this year, a relatively unknown startup from Finland made a startling announcement: It had finally solved solid-state batteries.
Key facts
- Last October, Toyota announced “the world’s first practical use of all-solid-state batteries in BEVs” by 2027 or 2028
- The companies probably have a ways to go,” said Alevtina Smirnova, director of the NSF Industry-University Cooperative Research Center for Solid-State Electric Power Storage
- Not only that, but Donut Lab, a spinoff of Verge Motorcycles, said that its solid-state battery — long considered the “Holy Grail of batteries” for their high-density, durable, fast-charging
- There was a crucial admission: The widely discussed “100,000 cycles” figure was a design target, he said, not an experimentally verified result
Summary
Not only that, but Donut Lab, a spinoff of Verge Motorcycles, said that its solid-state battery — long considered the “Holy Grail of batteries” for their high-density, durable, fast-charging abilities — would go into production later this year. Battery experts were understandably skeptical. “I can’t say they didn’t do it,” said Eric Wachsman, the director of the Maryland Energy Innovation Institute and an expert on solid-state batteries and solid oxide fuel cells. The skepticism seems warranted, especially when you consider how many other people have been chasing the solid-state dream.
