Seokyung AT Registers Patent for Boron Oxide-Based Solid Electrolyte Material for All-Solid-State Batteries

Nanomaterial specialist Seokgyeong AT announced on the 16th that it has completed domestic patent registration for its solid electrolyte material technology for all-solid-state batteries, titled 'Borate-based Solid Electrolyte and Its Manufacturing Method.'

The company also confirmed that its technology related to solid electrolyte materials, 'Borate-Molten Salt Based Solid Electrolyte and Its Manufacturing Method,' is in the final stages of patent registration.

In 2023, Seokgyeong AT succeeded in developing a new concept solid electrolyte material with a Boracite crystal structure and has been promoting it as a strategic new business to create future growth engines. Last year, the company established and began operating a dedicated cleanroom (analysis and evaluation room), enabling the acquisition of reliable data and smooth functional verification.

Unlike conventional sulfide-based solid electrolytes, which are sensitive to moisture and may generate harmful hydrogen sulfide gas, the borate-based solid electrolyte developed by Seokgyeong AT is not moisture-sensitive and has a low possibility of harmful gas generation, making it highly safe. Additionally, it offers excellent conductivity and uses low-cost raw materials such as borates, enhancing its price competitiveness.

A company representative stated, "Through the successful commercialization of borate-based solid electrolytes, we expect to lead innovation in the solid electrolyte battery industry and significantly expand the company's sales," adding, "The construction of the third plant, which will be equipped with mass production facilities for this material, is currently in its final stages."

Seokgyeong AT plans to build a strong entry barrier through a patent strategy based on its proprietary technology for solid electrolytes and continuous technological advancement, aiming to play a pivotal role in the related market by presenting a new paradigm in the secondary battery industry.

Meanwhile, Seokgyeong AT's third plant, located in Gimje-si, Jeonbuk, is scheduled to begin full-scale operation in April. The third plant will serve as a production base for the company's new business initiatives, handling mass production of ▲ solid electrolyte materials, ▲ hollow silica, and ▲ thermal interface materials (TIM) for electric vehicle batteries.
