In a significant milestone for the energy storage industry, the Korea Electrotechnology Research Institute (KERI) has made a breakthrough in all-solid-state batteries. Dr. Park Jun-woo and Sung Junghwan have developed a revolutionary technology focused on the size-controlled wet-chemical synthesis of solid-state electrolytes, paving the way for safer and more efficient battery solutions.
All-solid-state batteries are gaining popularity due to their reduced risk of explosion and fire, as they use solid-state electrolytes instead of liquid ones for ion transfer. However, the challenge lies in producing minute solid-state electrolytes, crucial for integration into the battery structure. KERI’s technology addresses this by enabling the mass production of tiny solid-state electrolytes with enhanced ionic conductivity.
Unlike traditional methods that involve large particle sizes and mechanical grinding, KERI’s approach streamlines the production process, reducing both time and cost significantly. By using microscopic raw materials and controlling the nucleation rate during chemical reactions, the research team was able to downsize the solid-state electrolytes without compromising quality. This innovative technique results in a remarkable increase in ionic conductivity compared to existing production methods.
Dr. Park emphasized the importance of selecting the right materials and controlling chemical reactions to simplify the production of solid-state electrolytes while maintaining high quality. This breakthrough not only meets the efficiency requirements for mass production but also opens up new possibilities for commercialization in the industry. KERI has already submitted patent applications for this technology and anticipates significant interest from companies in the battery sector.
As KERI plans to engage in technology transfer agreements with interested companies, the institute also aims to leverage its previous wet synthesis technique for solid-state electrolytes. By incorporating a patented special additive, KERI can now produce these electrolytes at a fraction of the cost, further solidifying its position as a leader in low-cost, high-quality battery solutions.
KERI’s breakthrough in all-solid-state batteries represents a significant step towards safer and more efficient energy storage solutions. By addressing the challenges of production and commercialization, KERI is poised to make a lasting impact on the battery industry and drive innovation in sustainable energy technologies.
