SK On (Seoul, South Korea) announced the completion of its pilot plant for all-solid-state batteries (ASSBs) in South Korea, marking a key step in its push to commercialize next-generation batteries by 2029. “This pilot plant will serve as a cornerstone for SK to leap forward as a strong and resilient company in addressing any changes in business environment,” Lee said. “We aim to remain at the forefront of commercializing all-solid-state batteries to accelerate electrification.”A pilot plant refers to a facility that produces prototypes and assesses and validates their quality and performance before full-scale production. SK On said its pilot plant will be primarily used to develop sulfide-based ASSBs, with some lines will be dedicated to lithium-metal batteries. ft.) pilot plant uses its own “Warm Isostatic Press (WIP)-free” technology for ASSB development, making it the first in South Korea to apply such solutions.
