First-principles study on Small Polaron and Li diffusion in layered LiCoO2
Seryung Ahn, Jiyeon Kim, Bongjae Kim +1
Li-ion conductivity is one of the essential properties that determine the performance of cathode materials for Li-ion batteries. Here, using the density functional theory, we inves…
Stability and electronic properties of layered NaMnO2 using the SCAN(+U)
Haeyoon Jung, Jiyeon Kim, Sooran Kim
Considering electron correlation appropriately is important to predict the properties of layered transition metal oxides, which have drawn a lot of attention as cathode materials f…
Large-gap insulating dimer ground state in monolayer IrTe2
Jinwoong Hwang, Kyoo Kim, Canxun Zhang +11
Monolayers of two-dimensional van der Waals materials exhibit novel electronic phases distinct from their bulk due to the symmetry breaking and reduced screening in the absence of…
Phonon study of Jahn-Teller distortion and phase stability in NaMnO for sodium-ion batteries
Haeyoon Jung, Jiyeon Kim, Sooran Kim
Cathode materials undergo various phase transitions during the charge/discharge process, and the structural transitions significantly affect the battery performance. Although phono…
