In a groundbreaking study recently published in Energy Storage Materials, the Korea Electrotechnology Research Institute (KERI) has achieved a significant milestone in the development of all-solid-state batteries. This advancement, spearheaded by Dr. Park Jun-woo and Sung Junghwan, represents a crucial step towards the commercialization of solid-state batteries that are free from the risks of explosion and fire.
The focus of the research conducted by Dr. Park and Sung Junghwan revolves around the “size-controlled wet-chemical synthesis of solid-state electrolytes (sulfide superionic conductors).” By engineering a technology that streamlines the production process, the team has managed to reduce processing time and costs by more than fifty percent, while also doubling the quality of the final product. Solid-state batteries utilize solid-state electrolytes instead of liquid components for ion transfer between the cathode and anode, significantly mitigating the risk of fire or explosion.
One of the key challenges in incorporating solid-state electrolytes into all-solid-state batteries lies in ensuring that the electrolytes are minute in size, approximately a few micrometers thick. KERI has developed a pioneering technology that can mass-produce these small solid-state electrolytes with enhanced ionic conductivity through a simplified process. This approach eliminates the need for additional processes such as mechanical grinding, thereby reducing both time and cost burdens associated with traditional production methods.
Dr. Park’s team employed microscopic raw materials and carefully controlled the nucleation rate of each material during chemical reactions to produce downsized solid-state electrolytes. This innovative method allows for the production of fine electrolytes using a straightforward wet synthesis technique, without the need for intricate processes. By successfully controlling the chemical composition, the team was able to achieve a remarkable ionic conductivity, exceeding that of existing production methods.
KERI has already submitted multiple patent applications for this groundbreaking technology and anticipates significant interest from the all-solid-state battery industry. The institute intends to enter into technology transfer agreements with companies that express demand for this innovative technology. Furthermore, KERI plans to leverage this achievement alongside a special wet synthesis technique, aimed at mass-producing solid-state electrolytes at a fraction of the current cost using a patented additive. This strategic move positions KERI as a leader in the low-cost mass production of high-quality solid-state electrolytes.
The research conducted by KERI represents a significant breakthrough in the field of solid-state battery technology. The innovative approach to producing solid-state electrolytes not only enhances efficiency and quality but also paves the way for the widespread adoption of all-solid-state batteries in the near future. With their sights set on commercialization and industry partnerships, KERI is poised to revolutionize the battery market and drive the next generation of energy storage solutions.
