제목 Combined First-Principles and Experimental Study on Multi-components Olivine Cathode for Lithium Rechargeable Batteries
초록 The electrochemical properties and phase stabilities of the multi-component olivine compound are studied experimentally and with first principles calculations. The formation of the solid solution from each single component olivine compounds is investigated by XRD study and the calculated first principles energy. We show that the solid solution of multi-components olivine is energetically favored at certain compositions. The electrochemical activity of the multi-components olivine is also investigated with conventional electrochemical characterization methods and first principles calculations. We also find that the delithiation mechanisms are significantly affected by a mixed transition metal distribution in the olivine framework. The evidence and its implication will be discussed in the talk.
