Solid-state batteries are expected to begin appearing in vehicles around 2025, with some manufacturers like MG planning to introduce them in specific models by the end of that year. However, widespread adoption across mainstream EVs is likely to occur closer to 2026 or later, as the technology continues to develop and scale.
According to recent reports, 2025 is shaping up to be a pivotal year for solid-state battery technology in the automotive industry. Autocar highlights that lighter and more efficient solid-state batteries are finally nearing commercial viability after years of delays, suggesting that 2025 could see initial deployments in certain vehicles [1]. Specifically, MG has announced plans to introduce a solid-state battery-powered SUV to the European market by the end of 2025, marking one of the earliest commercial applications [2].
Meanwhile, other automakers like Stellantis are targeting 2026 for the launch of vehicles equipped with solid-state batteries, such as the Dodge Charger, which indicates that while some models may feature this technology in 2025, broader adoption will likely take a few more years [3].
Additionally, companies like Toyota, Hyundai, and QuantumScape are actively working on solid-state battery tech, but these are still in development stages, and mass-market availability is not expected before 2026 or later [4].
In summary, while 2025 is poised to see the first commercial use of solid-state batteries in some vehicles, especially in niche or limited models, full mainstream adoption across the EV market is anticipated to unfold over the next few years as the technology matures and production scales up.
