Research

Nanotechnologies involve designing and producing objects or structures at a very small scale, on the level of 100 nanometres (100 millionth of a millimetre) or less. Nanomaterials are one of the main products of nanotechnologies – as nano-scale particles, tubes, rods, or fibres. Nanoparticles are normally defined as being smaller that 100 nanometres in at least one dimension. As nanotechnology develops, nanomaterials are finding uses in healthcare, electronics, cosmetics, textiles, information technology and environmental protection.

나노기술은 100 나노수준의 작은 범위에서 사물이나 구조등을 설계하거나 생산하는 것을 의미합니다. 이러한 나노기술의 주요 결과물 중의 하나는 나노 소재 (Nanomaterials)로서 최소 1차원 이상의 형태와 구조를 가지는 나노크기의 소재를 말합니다. 나노 기술의 발달에 따라 이러한 나노소재는 헬스케어, 에너지분야, 전자장치, 화장품, 섬유, IT, 환경 분야등 다양한 곳에서 활용되고 있습니다. 

Our researches aim at designing and synthesizing various nanostructured materials via novel fabrication methods including Hydro/Solvothermal Reaction, Wet-Chemical Process, Spray Pyrolysis, and Electrospinning Process. To make better their utilization, we optimize size, structure, morphology, chemical composition and functionality of nanomaterials. We also develope new synthetic processes for mass production of nanomaterials.

With the advancement of numerous electronic gadgets, smartphones, and electric vehicles, there has been a surge in recent research efforts focusing on battery systems for energy storage and supply. Specifically, lithium-ion batteries have become the most extensively researched energy storage solution due to their impressive energy density and minimal self-discharge rates.

In our laboratory, our research aims to synthesize and evaluate novel electrode materials to achieve lithium-ion batteries with greater capacity, increased output, and enhanced stability. Furthermore, we are also exploring electrode materials for sodium (Na) and potassium (K) ion batteries as potential alternatives to the costly lithium resources.

Electrochemical catalysts play a role in accelerating electrochemical reactions, reducing the energy needed for these reactions to occur. 

In our laboratory, we focus on developing affordable, high-performance, and durable non-precious metal catalysts to facilitate efficient electrochemical reactions. The primary application areas for these developed catalysts include hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR).

Lithium-ion batteries, the predominant energy storage devices in use today, face challenges in meeting the demands of high-capacity applications such as electric vehicles due to their inherent capacity limitations.

To address this issue, our laboratory is diligently working on developing materials suitable for next-generation battery systems with elevated energy densities, such as metal-air batteries and metal-chalcogen batteries.
