UNIST Professor Kim Geontae's Team Conducts Sample Tests and Files Patent for New Material
New Business for Electric Vehicle Heat Dissipation Substrates Using Ceramic Materials 추진
[Asia Economy Reporter Hyungsoo Park] Mico, a company specializing in ceramic materials and components, announced on the 5th that it is promoting the commercialization of solid electrolytes, a core material for next-generation all-solid-state batteries.
To commercialize solid electrolytes for all-solid-state batteries, Mico has completed sample testing and patent applications for new materials in collaboration with Professor Geontae Kim's team at UNIST. The recently filed patent covers a doped oxide-based solid electrolyte and its manufacturing method (gallium-terbium doped solid electrolyte for all-solid-state lithium secondary batteries and its manufacturing method), which is a key material that can enhance the performance of electric vehicle batteries.
Batteries, a core component of electric vehicles, are mostly LiBs (lithium-ion batteries) with liquid electrolytes, which offer high ionic conductivity but pose safety risks such as explosions. In contrast, solid electrolytes have lower explosion risks, higher safety, and advantages such as large capacity and high output.
The new oxide-based solid electrolyte material currently being developed by Mico showed a maximum ionic conductivity of 10-3 S cm-1 in sample tests. Additional research is actively underway to minimize interfacial resistance between the solid electrolyte and the cathode.
According to a survey by SNE Research announced earlier this year, the global market for solid electrolytes for secondary batteries is expected to reach 8 tons in 2022, 350 tons in 2025, 17,500 tons in 2028, and 76,000 tons in 2030. The market size is projected to be approximately 5 trillion KRW by 2030.
Professor Geontae Kim of UNIST, who is jointly developing with Mico, stated, "As the global electric vehicle adoption rate rapidly increases, safety issues are becoming prominent," adding, "Global automakers are experiencing a surge in demand for stable oxide-based solid electrolytes that can withstand external shocks."
In addition to the solid electrolyte business for all-solid-state batteries, Mico is developing thermally conductive heat dissipation substrates incorporating precision ceramic technology. Heat dissipation substrates are components that mainly release or transfer heat generated in electronic products such as CPUs and electric vehicles, with a global market size reaching approximately 1 trillion KRW in 2021.
