    Our laboratory focuses on

  • Design, synthesis, and characterization of Advanced Materials & Solid Electrolytes for next-generation battery systems
  • Their applications to prototype devices (e.g., All-Solid-State Batteries) in various fields like Electric Vehicles
  • Material-to-Cell Design and Characterization for all-solid-state battery

    Our laboratory aims

  • To understand complex phenomena in Energy Storage Systems (e.g., Lithium-ion Batteries) with knowledge about Electrochemistry & Materials Science
  • To elucidate mechanisms
  • To solve the current tasks and to devise new concepts and technologies
  • 본 연구실은 이차전지용 차세대 전극물질과 고체전해질 소재의 개발 및 분석, 그리고 이를 이용한 리튬이온전지 및 전고체전지 연구를 진행합니다. 최종적으로 전지 설계의 신뢰성 향상을 위해, 설계 검증을 위한 평가 프로토콜을 개발하는 연구를 진행합니다. 이는 안전한 고성능의 전기자동차 등에 적용될 수 있습니다.

    이러한 연구를 통해, 전기화학 및 물질과학 지식을 기반으로 전지(예. 리튬이온 전지, 전고체전지)에서 일어나는 현상을 이해하고, 메커니즘을 규명하며, 이를 바탕으로 기술적인 문제를 해결하여 새로운 개념, 기술 및 소재를 고안하는 것을 목표로 합니다.
