In a groundbreaking move in electric vehicle technology, automotive giant Toyota is launching its first electric vehicle equipped entirely with a solid-state battery by 2027 or 2028. The company states that these next-generation batteries will offer critical advantages such as longer range, faster charging times, and higher performance.
Toyota to Launch Solid-State Battery
Toyota aims to accelerate its investment in solid-state battery technology and achieve its first application globally. To achieve this goal, the company announced a new partnership with Sumitomo Metal Mining.

Through this partnership, it plans to begin mass production of cathode materials, a key component of batteries. Toyota and Sumitomo Metal Mining have been developing cathode materials for solid-state electric vehicle batteries since 2021.
The company announced that it has developed a high-durability cathode material thanks to Sumitomo’s unique powder synthesis technology. This process overcomes significant challenges faced in mass production.
Unlike the liquid electrolyte used in conventional batteries, solid-state batteries use a solid electrolyte. Toyota emphasizes that this structure offers the advantages of more compact size, higher power output, and longer lifespan.
Toyota, which received permission to produce the new batteries in Japan last month, is collaborating with key partners such as Idemitsu Kosan for the market launch.
Earlier this year, Idemitsu announced plans to build a large-scale production facility for lithium sulfur, which is used in all-solid-state electric vehicle batteries. Once operational, the facility will have an annual production capacity of 1,000 metric tons of lithium sulfur. Idemitsu also aims to mass-produce the batteries in 2027.
While Toyota claims to be a pioneer with this technology, competition in the global market is increasing. Other automotive giants, such as CATL and BYD, which dominate the global battery market, are similarly aiming to launch their new battery technology around 2027.
