Professor Seong Jae-kyung’s research team in the Department of Materials Science and Engineering secures stabilization technology for ‘high-energy all-solid-state batteries,’ a key technology for electric vehicles and robots.

Professor Seong Jae-gyeong’s team at Gyeongsang National University conducts research to enhance the stability of all-solid-state batteries for “Physical AI” ▸Focused analysis of interfacial reactions and cracking issues in high-Ni cathodes ▸Proposed a coating strategy to stabilize lithium-ion transport in all-solid-state batteries ▸Suggested development directions for high–energy-density, high-safety all-solid-state batteries As Physical AI–based industries—such as AI robots, autonomous vehicles, drones, and electric vehicles—grow rapidly, demand is increasing for next-generation batteries that simultaneously offer high energy density and excellent safety. In particular, all-solid-state batteries are attracting attention as next-generation energy storage technology that can enhance safety by replacing flammable liquid electrolytes with solid electrolytes. Against this backdrop, the research team led by Professor Seong Jae-gyeong in the School of Materials Science and Engineering (Metallurgical and Materials Engineering major), College of Engineering, at Gyeongsang National University (GNU; President Kwon Jin-hoe) comprehensively analyzed interfacial degradation issues that arise between high-Ni cathodes—the core material of all-solid-state batteries—and sulfide-based solid electrolytes, and presented an interfacial engineering design strategy to resolve them. Nickel-based cathodes are used as key cathode materials for electric vehicles and next-generation high-energy batteries due to their high operating voltage and excellent capacity characteristics. In particular, increasing the nickel content enables higher energy density, making them promising cathode materials even for all-solid-state batteries. However, as nickel content increases, problems such as surface structure collapse, oxygen release, transition-metal dissolution, microcracking, and the formation of residual lithium compounds become more severe during charge and discharge. Especially in all-solid-state batteries, unlike with liquid electrolytes, the cathode and solid electrolyte form a solid–solid interface, so even slight interfacial reactions or contact loss can directly lead to battery performance degradation. Cathode materials with high nickel content are advantageous for boosting battery energy density, but repeated charging and discharging can cause the surface structure to collapse, oxygen to escape, and fine internal cracks to form, leading to performance decline. In particular, in all-solid-state batteries, unlike conventional lithium-ion batteries, the cathode and solid electrolyte are in direct contact in the solid state; thus, even a small deterioration in contact between the two materials makes lithium-ion transport difficult and leads to performance degradation. In this paper, Professor Seong’s team comprehensively analyzed the major issues that occur between Ni-based cathodes and sulfide solid electrolytes. Representative issues include impeded lithium-ion transport at the cathode/solid-electrolyte interface, decomposition of the solid electrolyte at high voltages forming resistive layers, and cracking of cathode particles during charge/discharge that severs contact. The team proposed cathode-surface coating technology as a key strategy to solve these problems. The coating layer serves as a protective barrier that reduces direct reactions between the cathode and solid electrolyte and helps lithium ions move stably. The paper compares the pros and cons of various coating materials—including oxides, phosphates, and solid-electrolyte-based materials—and summarizes the requirements for an effective coating layer. It emphasizes that the coating must not only be chemically stable, but also allow lithium ions to pass readily while blocking unnecessary electron transport, and withstand cracking and delamination during cycling. The team also explained that simply coating the cathode surface is not enough to extend the life of all-solid-state batteries; factors such as cathode particle size and structure, doping, and the distribution of solid electrolyte within the electrode must also be considered to achieve both high performance and stability in practical cells. Professor Seong stated, “The performance limits of all-solid-state batteries arise not merely from the cathode material itself, but from complex chemical and mechanical degradation at the interface where the cathode and solid electrolyte meet,” adding, “This study is significant in that it presents interfacial engineering design criteria for the stable application of high-energy Ni-based cathodes in all-solid-state batteries.” He continued, “To realize high-safety, high–energy-density batteries required in Physical AI, electric vehicles, robots, and aerospace/mobility fields, an integrated approach is needed that encompasses not only material performance but also interfacial stability, electrode structure, and manufacturing processes.” This research featured Dr. B. Jeevanantham as the 1st author and was published on May 9 in the internationally renowned journal 《Journal of Energy Chemistry》 (IF: 14.9, top 3.4% in JCR) (paper title: Interface Engineering Strategies to Enable Stable Ni-Rich Cathodes in All-Solid-State Batteries: A Review).

Gyeongsang National University Professor Beomjin Park’s paper accepted to the International Conference on Machine Learning (ICML) ▸A top-tier international conference in machine learning and artificial intelligence… will be held at COEX in Seoul in July Revolutionizing tabular data analysis performance with TabularBERT (a BERT model for tabular data) Beomjin Park, a professor in the Department of Information and Statistics, College of Natural Sciences, at Gyeongsang National University (GNU; President Jinhoe Kwon), has had his paper “TabularBERT: Binning-Based Self-Supervised Learning for Tabular Representation” accepted for publication by the International Conference on Machine Learning (ICML), a top-tier international conference in the field of machine learning and artificial intelligence. ICML, together with the Conference on Neural Information Processing Systems (NeurIPS) and the International Conference on Learning Representations (ICLR), is a premier top-tier international conference representing the field of machine learning and artificial intelligence, and a leading venue for AI research worldwide. It is also classified as an S-tier conference in the AI/ML field on the Korean Institute of Information Scientists and Engineers’ list of excellent conferences and is included in the National Research Foundation of Korea’s BK21 Computer Science list of outstanding international conferences, reflecting its high prestige within Korea’s research evaluation system. This study proposes a new artificial intelligence learning method to effectively analyze tabular data used across diverse industries, including finance, healthcare, and manufacturing. While conventional deep learning models achieve excellent performance on image and text data, they have limitations on tabular data, failing to fully capture complex relationships among variables and the structural characteristics of the values. Professor Beomjin Park’s research team proposed a new method that tokenizes numerical data by converting it into intervals and learns interactions among variables within a Transformer architecture. In particular, through self-supervised learning, it effectively learns the intrinsic structure of the data and is designed to learn representations while preserving the order information of values, thereby improving both performance and stability compared to existing methods. Professor Park Beom-jin said, “This study improves the representation learning approach for tabular data—the format most commonly used in real-world data analysis—and is expected to contribute to performance improvements across various data analysis and prediction tasks.” The paper accepted this time is scheduled to be presented at the International Conference on Machine Learning (ICML), which will be held at COEX in Seoul in July 2026.

Research team of Professors Jeongseok Oh and Dongjun Kwon in the Polymer Engineering major secures high-durability polyurethane technology that withstands extreme environments

Research on domestic production of materials that maintain structural stability even under aviation fuel exposure Gyeongsang National University–Korea Institute of Ceramic Engineering and Technology Joint Research Outcomes Domestic production of high-performance sealant materials based on nano-interfacial design for enhanced oil resistance A joint research team led by Professors Jeong-Seok Oh and Dong-Jun Kwon of the Polymer Engineering major, Department of Materials Science and Engineering, College of Engineering, Gyeongsang National University (GNU; President Jin-hoe Kwon), together with Dr. Hyungmi Lim of the Korea Institute of Ceramic Engineering and Technology (KICET), has succeeded in localizing “polyurethane sealant technology” that can maintain structural stability even in extreme fuel exposure environments such as jet fuel. The results of this study were published in the April 21 issue of the internationally renowned journal in the field of polymer degradation and stability, Polymer Degradation and Stability (IF 7.4, top 6.9% in the Polymer Science category), under the title "Influence of SiO₂ Surface Functional Composition on the Oil Resistance of Polyurethane Sealants." This study was conducted based on the inter-institutional convergence of expertise. Professor 오정석’s laboratory was responsible for lifetime analysis of organic elastic functional materials and research to improve their durability, while Professor 권동준’s laboratory conducted research to enhance the adhesion of composite functional materials and optimize interfacial composition. Dr. 임형미’s research team at 한국세라믹기술원 led the collaborative research, supporting the development of functional inorganic particles based on silica material design and analysis technologies. In the aerospace and heavy industry sectors, polysulfide-based sealants have predominantly been used in environments that demand extreme oil resistance. However, these materials can present toxicity and odor issues due to the use of heavy metals during curing, and there are concerns that their use may be restricted as environmental and safety regulations tighten. Furthermore, from the perspective of ensuring long-term durability in high-vibration, high-load environments, there is an ongoing need to improve sealant formulations. Consequently, there is a growing need for research to enhance the oil resistance of polyurethane-based sealants, which are relatively lightweight, fast-curing, and highly durable. The research team precisely analyzed the microscopic oil ingress pathways occurring within the sealant and at the silica-polymer interface, and proposed a nanointerfacial design strategy to block them. In particular, by controlling the surface composition of silica nanoparticles to strengthen interfacial bonding with the sealant and to form a 'nodular' barrier structure, they effectively blocked oil diffusion pathways. As a result, they succeeded in suppressing oil-induced swelling (an increase in volume when a polymer compound absorbs a solvent) to within about 20%, while simultaneously improving the oil resistance and durability of polyurethane-based sealants. In the aerospace sector, the localization of materials and components is regarded as a key task that will determine the future competitiveness of the nation and its regions. Just as the global functional materials company PPG Industries leads the aerospace materials market, high-performance materials technological capabilities are directly linked to national aerospace competitiveness. As external uncertainties have increased recently, the importance of localizing aerospace and defense materials has been further emphasized domestically, and related technology development is being actively pursued, centered on Gyeongsangnam-do. Currently, with support from 한국산업기술진흥원 under 산업통상부 and 경상남도, the ‘Super-Gap Technology Development and Demonstration Project for Aerospace and Defense Sealant Materials’ is being carried out, led by 한국건설생활환경시험연구원 (KCL). In addition, a localization and demonstration center for aerospace and defense sealants is operating in 경남 양산, accelerating technology development and testing/verification in the functional materials field. Building on this infrastructure, technological cooperation with end-user companies such as 한국항공우주산업 (KAI) is expanding, and industry–academia–research collaboration frameworks—such as 노루페인트–경상국립대학교 and 세론테크–한국세라믹기술원—are also being strengthened. The 1st author, undergraduate researcher 김윤지, actively participated in the entire research process and played a key role in analyzing oil penetration behavior and elucidating its mechanism at multiple interfaces within sealants using nanoparticles. This case demonstrates that advanced research can be conducted even at the undergraduate level and well illustrates the capacity of 경상국립대학교 신소재공학부 to nurture research-oriented talent. Moreover, Dr. 양성백, a Research Professor at 그린에너지융합연구원, played a pivotal role in this study, which made it possible to achieve good results. This shows that a systematic research infrastructure within the university’s research institutes has been effectively established. 권동준 교수는 “이번 연구는 단순한 내유성 향상을 넘어, 극한 환경에서 기능재의 수명을 결정짓는 계면 설계의 중요성을 제시한 성과”라며, “앞으로도 항공우주용 복합 기능재 및 첨단 고분자 분야에서 지속적인 연구성과를 창출하고, 우주항공, 방산, 도심항공교통(UAM) 등 다양한 분야에서 핵심적인 표면·계면 소재 개발을 선도해 나가겠다.”라고 말했다. ㅇ 사진 설명: (1) 제1저자 김윤지 학부연구생, 양성백 박사, 오정석 교수, 권동준 교수, 임형미 박사 (2) 실리카 나노입자 표면 개질 및 폴리우레탄 실란트 제조 공정 모식도 ㅇ 내용 문의: 경상국립대학교 신소재공학부 권동준 교수 055-772-1656 This page is provided via AI machine translation.

Choi Ye-jin, a master’s student in the Department of Pharmacy, wins the Pharmaceutical Society of Korea’s "Future Pharmaceutical Sciences Outstanding Paper Award."

Ye-jin Choi, a master’s student at Gyeongsang National University, receives the Future Pharmaceutical Sciences Outstanding Paper Award. ▸At the 2026 Spring Academic Conference of the Pharmaceutical Society of Korea ▸Paper: Enhancing the expression efficiency of mRNA therapeutics by targeting TRIM25 Ye-jin Choi, a master’s student in the Department of Pharmacy at Gyeongsang National University (GNU; President Kwon Jin-hoe), received the Future Pharmaceutical Sciences Outstanding Paper Award (PSK Travel Award) at the 2026 Spring International Conference of the Pharmaceutical Society of Korea held at Cheongju Osco on April 24. At this conference, Ms. Ye-jin Choi presented research titled “Enhancing mRNA therapeutic expression by targeting TRIM25” (advisor Professor Seongchan Kim) and received high evaluations. Recently, mRNA-based therapeutics have attracted attention in diverse fields such as vaccines and cancer treatment; however, exogenously administered mRNA stimulates the innate immune system, limiting protein translation efficiency. In this study, Ms. Choi focused on the protein TRIM25, an E3 ubiquitin ligase involved in antiviral responses. The team transiently suppressed TRIM25 expression in cancer cells using nanocarriers and small interfering RNA (siRNA), confirming that protein expression from the model mRNA p53 increased markedly compared with the control group. This revealed TRIM25 as a key factor that hinders efficient translation of mRNA in vivo, and it was highly valued for presenting a new strategy to overcome intracellular delivery barriers of mRNA therapeutics and maximize anticancer efficacy. Ms. Choi said, “I am very honored to receive such a meaningful award from a prestigious society, and I am sincerely grateful to my advisor and my lab colleagues for guiding the direction of the research,” adding, “I will devote myself to follow-up studies so that this work can make a practical contribution to the advancement of the mRNA therapeutics platform.” Advisor Professor Seongchan Kim said, “As a master’s student, she persevered through a highly challenging project and produced meaningful results; I am proud,” adding, “Since this award is intended to support the challenges and innovations of young researchers who will lead future pharmaceutical sciences, I expect she will become a core talent who will play a pivotal role in developing next-generation mRNA anticancer agents utilizing nanotechnology.” This study is a representative outcome derived from the research support system of the Pharmaceutical Research Institute and the RISE project (Gyeongsangnam-do Settlement-Oriented Research-Centered Advanced Talent Training Program), and is regarded as a case demonstrating that systematic research guidance and an experiment- and verification-centered research environment are leading to genuinely outstanding academic achievements.
