○ All-solid-state batteries (ASSBs) refer to a type of battery whose major components are all made of solid materials. With increased safety and improved space utilization, they offer the potential to address the technical limitations of traditional lithium-ion batteries.

○ Unlike secondary batteries that use organic liquid electrolytes, ASSBs use solid electrolytes and pose little risk of fire or explosion. They do not require separators or cooling systems, placing them in a better position to improve space utilization and energy density. Moreover, with fewer parts and materials needed for battery stability, they can be made smaller than conventional batteries. 

○ The global ASSB market size is projected to expand at an average annual growth rate of 34.2% from USD 61.5 million in 2020 to USD 482.5 million in 2027. Similarly, the domestic ASSB market is expected to grow at an average annual growth rate of 41.0% from USD 2.92 million in 2020 to USD 32.3 million in 2027.

○ Jeonbuk State has already secured the core competency for ASSBs by attracting companies across the industry value chain for secondary batteries. Given the LQ index and NOHI of 2.65 and 0.0497, respectively, the region is relatively specialized in ASSBs.

○ (Policy recommendations: R&D) 1) Promote customized R&D for early commercialization in key demand markets, 2) select and support large-scale R&D projects to develop manufacturing technologies as well as core strategic technologies for materials, parts, and equipment, and 3) secure “super-gap” technological competitiveness to stay ahead of the curve.

○ (Policy recommendations: ecosystem expansion) 1) Establish proactive response systems with a focus on Jeonbuk State’s key industries, 2) expand support for key ASSB companies and companies specializing in material/part/equipment production to help them secure sustainable growth and technological progress, 3) develop and operate demand-based training programs and establish on-site labor supply systems, and 4) expand inter-regional cooperation, such as by exploring transregional projects.

○ (Policy recommendations: foundation underpinning) 1) Secure super-gap technologies and nurture global and transregional talent and 2) establish and operate core institutions dedicated to corporate support/collaboration platforms.
