Supercapacitors
Pore and non-porous maximized porous and hybrid structures can absorb a lot of ions and can be applied to energy storage devices such as Supercapacitor to achieve improved energy density. In particular, the hybrid structure controlled at the atomic level has excellent mechanical / electrical characteristics and is attracting attention as a next generation energy storage device having high output characteristics and high energy density.

Asymmetric Hybrid capacitors
Composite materials hybridized with carbon materials and metal oxide particles can control the rate of reaction and can be applied to high power with similar energy output density and energy storage density similar to existing batteries. Porous carbon structures using pores, The metal oxide particles can be transported to the metal oxide particles more efficiently, thereby increasing the efficiency of the oxidation-reduction reaction. Moreover, the metal oxide particles have a maximum capacity capable of reducing the size of the particles to a very small atomic unit. It is expected that the present invention can be applied to other types of devices, such as high energy density and power density.

Lithium-ion Batteries & Next-generation Batteries
The various materials developed in the course of the research can be applied to both the cathode and the anode, which are the largest components of the lithium secondary battery. Previous studies have shown high capacity and high stability characteristics as the electrode material. In addition, composite materials of metal oxide particles and carbon materials hybridized with lithium and exhibited high-capacity negative electrode characteristics. When the kind of metal oxide is replaced with a lithium secondary battery which can be used as an anode, Can be applied to next-generation energy storage devices having high capacity and high output characteristics at the same time
