Co-precipitation is a widely adopted synthesis method for layered oxide cathode materials, offering excellent compositional control and scalability. The uniformity and microstructure of co-precipitated precursors play a critical role in determining the electrochemical performance of the final cathode. Our research focuses on synthesizing high-performance layered cathodes through rational precursor design, with precise control over morphology and composition via co-precipitation techniques. In parallel, we are developing doping strategies to control the spatial distribution of dopants within the crystal structure. These approaches aim to enhance the structural stability and electrochemical durability of next-generation cathode materials. As the demand for electric transportation continues to rise, the need for high-energy-density lithium-ion batteries is becoming increasingly critical. However, graphite, the most widely used anode material, has reached its theoretical capacity limit, necessitating the development of novel anode materials for next-generation battery systems. In response, our research group is working to improve cycle stability by surface-engineering high-capacity anode materials such as silicon and lithium metal. Furthermore, in the field of sodium-ion batteries, we are focusing on hard carbon anodes, particularly by tuning their morphology and internal pore structure through precursor-level modifications. Functional materials such as porous materials and MXenes can be used in various research fields such as catalyst, sensor, separation, and drug delivery as well as energy device due to the new physical/chemical properties of materials. By applying porous materials to energy devices, we can expect increased capacity and power performance owing to the larg
