Japanese legacy automaker Toyota’s groundbreaking solid-state batteries will apparently be more limited to a “few thousands” than initially expected, Electrek reported.
Toyota’s battery breakthrough
In June, Toyota introduced its battery roadmap during a tech briefing as it aims to advance in the electric vehicle industry. It includes two next-gen battery technologies: a performance and a popularized version.
Toyota expects the performance version to roll out in 2026. It plans to equip these new batteries to its next-gen models with a CLTC-estimated 620 miles (1,000 km) range.
Meanwhile, the popularized version will supposedly cut production costs by 40% and improve driving range by 20%. It will reportedly include LFP batteries, according to Electrek. Toyota plans to advance the battery to practical use by 2026 to 2027.
The Japanese automaker also plans to launch a high-performance battery employing a bipolar structure and high nickel cathode, which can boost range by 50%.
Here’s Toyota’s battery technology roadmap:
| Battery | Type | Production Start | Driving Range, miles (approx.) | 10%-80% Charging Time (approx.) |
| Current (bZ4X) | Prismatic Monopolar Li-ion | 2022 | 380 | 30 mins |
| Next-generation Performance | Prismatic Monopolar Li-ion | 2026 | 620 | 20 mins |
| Next-generation Popularization | Bipolar Lithium Iron Phosphate | 2026-2027 | 450 | 30 mins |
| Bipolar/Performance Fusion | Bipolar Li-ion w/ High Nickel Cathode | 2027-2028 | 680 | 20 mins |
| All-Solid-State, First Batch | ASSB | 2027-2028 | 740 | 10 mins |
| All-Solid-State, Second Batch | ASSB | post-2028 | 930 | N/A |
Limited production
Toyota recently announced the development ramp-up of its solid-state batteries that can add 20% range and support fast charging in just 20 minutes, while the more powerful model can improve range by 50%.
The first one offers a driving range of 621 miles, and the other can surpass 745 miles, Toyota noted. The automaker plans to launch the battery tech as early as 2027 to 2028. However, production will be very limited.
Toyota Times recently reported that the batteries’ mass production will occur in 2030 and beyond with the help of Japanese partner Idemitsu Kosan.
Interestingly, the report noted that the planned solid-state battery production can only support the assembly of “over ten thousand vehicles.”
Toyota’s ambition battery roadmap is a crucial part of its wider electrification strategy as it seeks to compete in the rapidly growing market. Toyota set a sales target of 3.5 million EVs by 2030. Before that, it aims to add ten new EV models to its portfolio by 2026.
