Toyota is progressing towards the launch of its first solid-state battery-powered electric vehicle (EV) within the next two to three years. This timeline was reinforced by an executive during the Tokyo Motor Show. Recently, Toyota announced a partnership with Sumitomo Metal Mining Co. aimed at mass-producing this battery technology, emphasizing their commitment to making solid-state batteries a reality after years of development delays. They previously postponed the anticipated launch from 2020 to 2023, and then to 2026, but are now confident in their schedule.
At the event, Keiji Kaita, president of Toyota’s Carbon Neutral Advanced Engineering Development Center, reaffirmed that the company is on track for an introduction by 2028, highlighting the expected benefits of solid-state batteries, such as significantly increased driving range and reduced charging times. Kaita mentioned that while the specific model for the debut remains undecided, solid-state technology is crucial for the future of electric vehicles and will contribute to lowering emissions and environmental impact.
Chief Technical Officer Hiroki Nakajima stated that although current EV platforms could potentially incorporate solid-state batteries, a dedicated platform would better suit the new technology. Toyota has also unveiled a prototype solid-state battery pack, claiming it could offer a range of 745 miles and charge in under 10 minutes. To facilitate this, Toyota is collaborating with several Japanese firms, including Idemitsu Kosan, which plans to construct a large-scale production plant for lithium sulfide, an essential material for solid-state batteries, with mass production slated for 2027.
As part of a larger national strategy to reduce dependency on foreign battery supplies, Toyota is investing significantly in domestic battery production. The design for the battery includes plans to reduce its height to enhance range and efficiency in their vehicles, as showcased in the Corolla Concept displayed at the motor show. With competitive advancements by companies like Mercedes and evolving technologies from others in the industry, questions remain about whether Toyota can deliver its promises regarding solid-state batteries by the targeted timelines. Acknowledging the anticipation surrounding this technology, the automotive world watches closely to see if Toyota can finally bring its vision to fruition.
