Toyota provided insights into its battery development strategy. The current lithium-ion 64-kilowatt-hour batteries can fast-charge from 10% to 80% in about 30 minutes. However, future Toyota batteries will feature next-generation prismatic “performance” lithium-ion batteries with twice the range, a 20% cost reduction, and a rapid 20-minute charge from 10% to 80%. These “performance” batteries are expected to debut in 2026, available in two sizes for SUVs and smaller cars.
Additionally, Toyota plans to offer a “popular” version of these batteries, utilizing more affordable lithium-iron-phosphate (LFP) cells. These LFP batteries are projected to offer 20% better range than the bZ4x while being 40% cheaper and maintaining a 30-minute fast-charging time. These batteries are also slated for release in 2026 and 2027.
Toyota’s ultimate goal is solid-state batteries, aiming for 20% better range than “performance” lithium-ion batteries and a rapid 10-minute charge. Furthermore, Toyota envisions “better” solid-state batteries with 50% improved range over “performance” lithium-ion batteries. Commercial use of these solid-state batteries is anticipated by 2027 or 2028.
