Nataly Carolina Rosero‐Navarro 교수의 연구실은 고체전지의 핵심 소재인 고체 이온 도전체, 특히 희토류산화물 기반 가르네트 구조 전도체와 황화물 기반 고체 전해질의 개발에 중점을 두고 있습니다. 높은 리튬 이온 전도도와 안정성을 확보하기 위해 소결 조건 최적화, 유리 첨가제를 이용한 밀도 향상, 그리고 전극과 전해질 간의 인터페이스 저항 감소 전략을 연구하고 있습니다. 또한 유기-무기 하이브리드 페로브스카이트 소재를 리튬이on 배터리의 전극 재료로 응용하는 새로운 접근성도 탐구하고 있습니다.

A solid electrolyte with a small particle size, good mechanical properties and high ionic conductivity is required to achieve high energy and power density in the all-solid-state battery.
Lithium ion conductors with garnet‐type structure are promising candidates for applications in all solid‐state lithium ion batteries, because these materials present a high chemical stability against Li metal and a rather high Li + conductivity (10 −3 –10 −4 S/cm). Producing densified Li‐ion conductors by lowering sintering temperature is an important issue, which can achieve high Li conductivity in garnet oxide by preventing the evaporation of lithium and a good Li‐ion conduction in grain bound
An effective strategy to lower interfacial resistance between NMC and a garnet-structured solid electrolyte with a Li<sub>2</sub>SiO<sub>3</sub> interlayer.
Organic–inorganic hybrid perovskite materials have recently been investigated in a variety of applications, including solar cells, light emitting devices (LEDs), and lasers because of their impressive semiconductor properties. Nevertheless, the perovskite structure has the ability to host extrinsic elements, making its application in the battery field possible. During the present study, we fabricated and investigated the electrochemical properties of three-dimensional (3D) methylammonium lead mi
