Suzuki Motor Corporation has taken a significant step toward the future of electric vehicles by acquiring the all-solid-state battery business of Kanadevia Corporation. The move places Suzuki among a growing group of automakers betting on solid-state battery technology as the next major breakthrough in EV development.
The agreement, announced on March 4, will see Suzuki gain access to Kanadevia’s advanced solid-state lithium battery technology, including its proprietary dry manufacturing process. The acquisition is expected to be finalized on July 1, 2026, giving Suzuki full control of a battery program that has been under development for nearly two decades.
A Long-Developed Technology With Real-World Applications
Kanadevia has been researching all-solid-state lithium batteries (AS-LiB) since 2006. Unlike conventional lithium-ion batteries that use liquid electrolytes, solid-state batteries rely on solid materials to transfer ions between electrodes. This design offers several potential advantages, including improved safety, higher energy density, and greater durability.
One of the most notable demonstrations of the technology came in February 2022, when Kanadevia collaborated with the Japan Aerospace Exploration Agency to launch a spacecraft equipped with solid-state batteries to the International Space Station. The mission marked one of the first real-world uses of this technology in space, highlighting its ability to operate reliably in extreme conditions.
According to Kanadevia, its solid-state batteries can function across a wide temperature range, from −40°C to +120°C, making them suitable for demanding environments such as aerospace applications. The batteries have also demonstrated strong safety performance. In nail penetration tests — a scenario designed to simulate severe battery damage — the cells reportedly did not ignite, smoke, or explode. Traditional lithium-ion batteries typically fail under the same conditions.
Why Solid-State Batteries Matter for EVs
The global automotive industry has increasingly focused on solid-state batteries because they could solve several of the biggest limitations facing electric vehicles today.
First, solid-state batteries promise higher energy density, which could enable EVs to travel significantly longer distances on a single charge. Second, they offer improved safety, as the solid electrolyte eliminates many of the flammability risks associated with liquid electrolytes. Finally, they could potentially support faster charging speeds and longer battery lifespans.
Major automakers including Toyota, Nissan, and Honda have already announced ambitious plans to develop solid-state battery technology over the next decade. Suzuki’s acquisition signals that it intends to compete in the same technological race.
Suzuki’s Growing EV Strategy
Although Suzuki has historically focused on small, efficient vehicles and hybrid technology, the company is now expanding its electric vehicle lineup. In late 2025, Suzuki launched its first mass-produced EV, the Suzuki e Vitara, which shares its platform with the Toyota Urban Cruiser EV through Suzuki’s partnership with Toyota.
By securing access to advanced battery technology, Suzuki may be positioning itself to develop future EV models with greater range, improved safety, and lower long-term operating costs.
Final Thoughts
Suzuki’s decision to acquire Kanadevia’s solid-state battery business highlights how critical battery technology has become in the competition among automakers. While solid-state batteries are still several years away from large-scale commercialization, companies that develop or secure access to the technology early could gain a significant advantage.
In my view, the move shows Suzuki is preparing for the long-term transition to electric mobility. If solid-state batteries achieve their promised performance improvements, they could transform not only Suzuki’s future EV lineup but also the broader electric vehicle market.
