Overview

Our group’s main research interests lie in developing nanomaterials with a controlled structure by applying the phase separation phenomenon in the nanoscale and applying them to energy storage devices including lithium-ion secondary batteries (electrode active materials, electrodes, separators, etc.). Therefore, we focus on developing high performance energy storage systems with functional energy materials.

Nanomaterials

Nanomaterials can be used in various research fields such as catalysts, sensors, separation, and drug delivery as well as energy storage due to the new physical/chemical properties of materials appearing in the nanoscale. Recently, in addition to nano-materialization, research on precisely controlled 3D structure in the nanoscale is being conducted. In our laboratory, we are working on the development of multifunctional nanomaterials with controlled size, shape, and composition by using the phase separation phenomenon that occurs in a complex mixture of organic and inorganic materials.

  • Understanding/application of phase separation of organic/inorganic materials

  • Development of multi-functional nanostructured materials with controlled size, shape and composition

  • Precise analysis of nanostructured materials
