Abstract

ABSTRAKFasa Li2Sc3(PO4)3 merupakan material konduktor superionik yang dapat diaplikasikan sebagai baterai yang dapat diisi ulang (rechargeable). Ion Li+ dalam struktur Li2Sc3(PO4) dapat mengalami migrasi dari posisi terisi ke posisi kosong. Penelitian ini telah memodelkan migrasi ion Li+ dalam struktur Li2Sc3(PO4) dengan menggunakan metode bond valence sum (BVS). Metode ini dapat memprediksi bilangan oksidasi suatu atom berdasarkan jarak dengan atom-atom tetangga. Source code berbasis BVS yang digunakan adalah JUMPITER yang mensimulasi efek gaya listrik eksternal yang bertindak pada ion litium sehingga nilai BVS litium dapat dipetakan terhadap jarak. Hasil simulasi menunjukkan bahwa konduksi ion Li+ dapat terjadi pada arah [010], [101], dan [120]. Namun, lintasan konduksi ion Li+ lebih mudah terjadi pada arah [120] atau bidang ab dengan nilai maksimum BVS adalah 0,982.ABSTRACTg-phase of Li2Sc3(PO4)3 is a lithium super ionic conductor which can be applied as a rechargeable lithium battery. Lithium ions of g-Li2Sc3(PO4)3 can migrate from occupied site to vacant site. In this research, simulation of Li+ ions migration in the structure of g-Li2Sc3(PO4)3 carried out using bond valence sum (BVS) to predict the oxidation state of Li+ion based on the distance of the ion to neighboring atoms. BVS-based code used JUMPITER to simulate the effect of external electrical force acting on the lithium ions to produce the lithium BVS value which can be mapped to the distance. The simulation results shows that Li+ ion conduction can be occurred on [010], [101], and [120] directions. However, the Li ion conduction pathway occur more easily in the direction of [120] or ab plane with the BVS maximum value is 0.982.

Abstract

This study aims to determine the effect of Mn3+ and La3+ dopants on the structure of PbBi2Nb2O9 (PBN) using atomistic simulation. PBN phase geometry was optimized before the Mn3+ and La3+-doped phase. Mn3+ partially substituted octahedral Nb5+ in the perovskite layer. While La3+partially substituted Bi3+ in the bismuth layer and dodecahedral Pb2+in the perovskite layer. The concentration (x) of dopants that doped PBN was made in such a way that it produces a phase of Pb1-2xBi1.5 + 2xLa0.5Nb2-xMnxO9 (x = 0, 0.1, and 0.3) which was not charged. The simulation results showed that the optimized PBN cell parameters were in a good agreement with the experimental result. Increasing the concentration of dopants result in the Pb1-2xBi1.5+ 2xLa0.5Nb2-xMnxO9 phase (PBNM-Bi and PBNM-A) being less stable, as indicated by the increased lattice energy. PBNLM-Bi structures experiences an elongation which was showed by the cell parameters of c increase while a and b decrease. La3+prefers to occupy bismuth oxide layer rather than the dodecahedral A-site of the perovskite layer. The results of this simulation can explain the PBLNM structure of experimental results that do not pay attention to the multiplicity of doped PBN with certain dopant concentrations.
