could be the breakthrough we’re waiting for. Replacing liquid electrolytes in EV batteries could yield more energy density, and thus more range. It could also make batteries safer, with less likelihood of thermal runaway and fire. It could provide better performance, longevity, and faster charging. Even if they’re not the next quantum leap in automotive technology, they could be a useful arrow in an automaker’s quiver, allowing more options for using the right technology in the right application.
One problem is that solid-state batteries are expensive to manufacture, and they still need widespread testing in order to be validated for use in the real world. Hyundai might be closer to the next big step in the journey to making solid-state EVs, according to a report from Korean Car Blog. It says Hyundai is putting the finishing touches on a solid-state production line, which would allow the automaker to begin testing the batteries and exploring mass production.
Testing Could Start In 2025
Hyundai is building its solid-state battery pilot production line at its R&D center in Uiwang, South Korea. A source close to the matter told KCB that the necessary equipment is almost all installed, with the construction of “logistics automation facilities” remaining to be finished. Full-scale operations could begin as early as January.
After that, Hyundai will be able to begin testing the batteries in prototypes in 2025. This would allow Hyundai to test the batteries in specific conditions, as well as real-world driving, identifying issues and solving them in order to ensure the technology’s readiness for mass production by 2030.
An Industry-Wide Race
Hyundai is not the only manufacturer working on bringing solid-state batteries to market. Toyota has spent years developing solid-state batteries, despite the company’s apparent aversion to committing to all-electric vehicles, and it seems particularly well-suited to making SSBs happen. Nissan is targeting 2028 to launch an SSB EV. CATL is reportedly close to trial production. Mercedes-Benz is aiming for a 600-mile EV using solid-state tech, as is Samsung. In fact, it seems most of the industry sees solid-state batteries as the next big thing for EVs.
With Hyundai (and others) so close to being able to actually test and validate the batteries for real-world use, it seems like the next few years will be exciting, especially for those who have been waiting for an advancement that could get the range-anxious into seats, quiet fears over fires, and make charging faster and easier for everyone.
