A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery. The batteries lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. Research areas for lithium-ion batteries include life extension, energy density, safety, cost reduction, and charging speed, among others.

We are primarily focused on the development of high-performance anode materials for LIBs. In particular, we are investigating next-generation anode materials based on alloy-type reactions, such as silicon and germanium, which offer significantly higher energy densities compared to commercially used graphite. Additionally, we are conducting research on advanced LIB technologies, including thick-film electrodes designed to meet the growing demand for high volumetric energy density, as well as high-performance electrode fabrication methods through the uniform dispersion of carbon nanotubes.
