On the Dash:
- Solid-state batteries promise faster charging, longer range, and safer, more energy-dense EVs.
- Major automakers are targeting mass adoption between 2027 and 2030, with prototypes already achieving impressive milestones.
- U.S. consumers may need to wait several years, though China currently leads in commercially available solid-state EVs.
Electric vehicles are on the cusp of a huge technological leap as automakers advance solid-state battery technology, which could improve driving range and charging speeds, according to a recent Cars.com report. Unlike conventional lithium-ion batteries, solid-state batteries replace liquid electrolytes with solid materials, making them safer, more energy-dense, and cheaper to produce.
Several automakers are actively testing prototypes, like:
- Mercedes-Benz partnered with Factorial Energy to power a prototype EQS sedan that drives 749 miles on a single charge, still leaving 85 miles of range.
- BMW is working with Samsung SDI and Solid Power to test solid-state batteries in i7 sedans.
- Stellantis is testing batteries in Dodge Charger Daytona EVs that can charge from 15% to 90% in just 18 minutes.
- Volkswagen debuted a Ducati electric motorcycle with a battery that charges from 10% to 80% in 12 minutes.
Japanese automakers are also making progress with initiatives such as:
- Toyota has prototypes that can charge from 10% to 80% in 10 minutes and deliver 620 miles of range. Mass production is expected in 2027-2028.
- Honda is aiming for 620 miles of range, but challenges with cell size are slowing progress.
- Nissan plans to offer solid-state batteries in vehicles by late 2028, including hybrids.
- Hyundai-Kia says widespread availability may not happen before 2030.
While solid-state batteries offer distinct advantages over current EV technology, their higher energy density could enable ranges exceeding 600 miles on a single charge, but, faster charging reduces driver downtime. The technology also reduces the fire risk associated with liquid electrolytes in lithium batteries for shipbuilding and enhances investment opportunities between the two nations.
Despite progress, consumer availability in the U.S. remains limited. While China already offers EVs equipped with solid-state batteries, mass adoption in the U.S. is expected later in the decade. Meanwhile, automakers continue to test prototypes, optimize production, and address technical challenges before these batteries become widely accessible.
