Journal ArticleDOI
First-principles study of native point defects in ZnO
TL;DR: In this paper, the first principles pseudopotential method was used to determine the electronic structure, atomic geometry, and formation energy of native point defects in ZnO and showed that both the Zn and O vacancies are the relevant defects.
Journal ArticleDOI
Ab initio study of lithium intercalation in metal oxides and metal dichalcogenides
TL;DR: In this article, the average voltage to intercalate lithium in various metal oxides was studied and it was found that Li is fully ionized in the intercalated compounds with its charge transferred to the anion and to the metal.
Journal ArticleDOI
Ab initio calculation of the intercalation voltage of lithium-transition-metal oxide electrodes for rechargeable batteries
TL;DR: In this article, a pseudopotential technique was used to predict the intercalation voltage of LiMO2 cathodes for metal oxides, which can be applied to predict properties of new compounds.
Journal ArticleDOI
Application of first-principles calculations to the design of rechargeable Li-batteries
TL;DR: In this article, first-principles pseudopotential calculations were used to predict the intercalation voltage of rechargeable Li batteries, and the results showed that Li inter-calation causes significant electron transfer to the oxygen ions in the structure.
Journal ArticleDOI
