In the US, Hyundai has secured a patent for an all-solid-state EV battery system equipped with a ‘pressurizing device’ and significantly improved operating temperatures. The automaker describes the technology as enhancing stability and energy density while reducing production costs.
Like most automakers, Hyundai considers solid-state packs as the next-generation battery technology. In October last year, Sung Nak-shop, head of Hyundai Motor Group’s R&D Planning, said that the group’s vision was 2030 for implementation in its range of electric cars.
Solid-state batteries replace the liquid electrolyte with a solid one, successfully mitigating the risk of thermal runaway fires while increasing range and charging speed. Now, the automaker has filed a patent in the US, titled “All-Solid-State Battery System Provided with Pressurizing Device,” granted on December 28, 2023. It unveils some more details on Hyundai’s strides in this field.
