In a recent study published in Energy Storage Materials, the Korea Electrotechnology Research Institute (KERI) has made a significant advancement in the field of all-solid-state batteries. Dr. Park Jun-woo and Sung Junghwan have developed a groundbreaking technology that focuses on the “size-controlled wet-chemical synthesis of solid-state electrolytes.” This innovation not only reduces processing time and costs but also enhances the quality of the solid-state electrolytes, making them safer and more efficient than traditional liquid electrolytes.
Traditional solid-state electrolytes used in all-solid-state batteries often pose challenges due to their large particle sizes, requiring additional processes like mechanical grinding. However, KERI’s new technology addresses this issue by producing minute solid-state electrolytes that are crucial for integration into the cathode of the batteries. By utilizing microscopic raw materials and controlling the nucleation rate during chemical reactions, KERI has achieved a remarkable reduction in size, resulting in enhanced ionic conductivity. This innovative approach simplifies the manufacturing process and eliminates the need for complex and costly refining techniques.
The successful control of chemical composition has led to a significant increase in ionic conductivity, surpassing that of conventional solid-state electrolyte production methods. Through years of experimentation and material analysis, the KERI research team has identified the ideal combination of materials, enabling them to achieve high-quality solid-state electrolytes suitable for mass production and commercialization. Dr. Park emphasized the significance of selecting the right materials and optimizing chemical reactions to streamline the production process while maintaining superior quality.
KERI has submitted several patent applications for this groundbreaking technology, anticipating widespread interest from the all-solid-state battery industry. The institute is prepared to engage in technology transfer agreements with companies seeking to leverage this innovative development. Additionally, KERI plans to integrate this achievement with a special wet synthesis technique designed to significantly reduce raw materials costs for solid-state electrolyte production. By combining these strategies, KERI aims to establish itself as a leader in the production of high-quality solid-state electrolytes at a lower cost.
Overall, KERI’s breakthrough in all-solid-state battery technology represents a significant step towards safer and more efficient energy storage solutions. By revolutionizing the production of solid-state electrolytes, KERI has opened new possibilities for the commercialization of all-solid-state batteries, paving the way for a more sustainable and secure energy future.
