From the article: Toyota Motor Corporation has announced a major advance in the race to develop all-solid-state batteries, a technology many experts call the “holy grail” of electric vehicles (EVs).
The company revealed on Wednesday that it has partnered with Sumitomo Metal Mining Co. to mass produce cathode materials for these next-generation batteries.
The automaker aims to launch its first all-solid-state battery-powered EV as early as 2027, potentially transforming the global EV landscape.
Both Toyota and Sumitomo said they have made progress in developing key cathode materials that could enable solid-state batteries to outperform today’s lithium-ion batteries.
“We aim to achieve the world’s first practical use of all-solid-state batteries in BEVs,” the Japanese carmaker said in its announcement.
Solid-state batteries differ from traditional lithium-ion cells by replacing the flammable liquid electrolyte with a solid one. This design could significantly improve energy density, safety, and lifespan.
The automaker stated that its new batteries would offer “smaller size, higher output, and longer life,” leading to vehicles with longer driving ranges and shorter charging times.
Solid-state versions are less prone to overheating than current EV batteries and can charge much faster. These advantages make them an appealing option for mass adoption if production challenges can be overcome.
“The new batteries could significantly enhance driving range, charging times, and output,” the mobility leader added, highlighting the company’s belief that the technology could reshape the future of automobiles.
Sumitomo’s role and Japan’s production ambitions
Toyota and Sumitomo have been jointly developing cathode materials for solid-state batteries since 2021. Their research has focused on solving long-standing challenges such as cathode degradation during repeated charging and discharging cycles.
Using Sumitomo’s proprietary powder synthesis technology, the companies claim to have developed a “highly durable cathode material.”
A Sumitomo spokesperson said, “We will prioritize supplying Toyota, then respond flexibly to market demand.” The company plans to start mass production of the new materials as early as Japan’s 2028 fiscal year.
This effort is part of Japan’s broader strategy to secure its domestic EV battery supply chain and reduce reliance on China and South Korea. Several Japanese firms, including Toyota, are investing around $7 billion (1 trillion yen) in local battery production. The government has also granted Toyota a METI certification to manufacture the new batteries in Japan.
This is what I’ve been waiting for. Limp my Prius along another two years and then get the solid state.
I didn’t realize this tech was far enough along for them to be predicting it in the next model year. Do they have any prototype or concepts announced? Why about pricing or preorders? I would think if they think they’re this close those things would be out by now or coming out soon
BYD is already testing their solid state battery vehicle. Toyota showing 2027 as their year doesn’t seem too far fetched.
Ah, yes. Toyota. Always at the forefront of EV development. /s
It would be pretty wild if the company that has dragged it’s feet on EV’s ends up coming out with a huge leap and becomes one of the market leaders.
They certainly have the power to do it though, they are still basically the worlds biggest car manufacturer, so if anyone can make a leap, it’s them.
Is it that time of year already? When Toyota claims to be on the cusp of the next big breakthrough in car technology to stop people buying EVs that actually exist and work, so they can keep selling their old-tech combustion cars?
Yeah, ok.
Toyota was gonna show their solid state battery EVs by the [2020 Tokyo Olympics](https://www.cnet.com/roadshow/news/toyota-solid-state-battery-elect).
I’ll believe it when people start buying it.
Toyota and solid state batteries is pretty much a running gag joke at this point.
Are we just not going to mention the many many times Toyota has touted this, going at least as far back as ~2018 for the ~2020 model year?
