제목 | First-principles study on the reaction mechanisms of the electrode materials for Li-ion batteries |
초록 | With the growing interest in power sources for large applications such as electric vehicle (EV), lithium-ion batteries are finding new opportunities in this emerging area. Intensive research efforts are focused on developing suitable electrode material, the key component of lithium-ion battery, for these applications. The electrode materials for lithium-ion batteries for use in EV require high stability, high power, high energy, and low cost. In this talk, I will present the first-principles results on the oxygen redox activity in Li-excess cathode materials[1] and the reaction mechanism of lithium titanate anode materials[2]. Fundamental understanding of the electrode's reaction mechanism based on first-principles calculations can accelerate to develop high-performing electrode materials. References [1] D.-H.
