Synthesis and Characterization of LiAl0.3Co0.7-xMgxO2 with High Electrical Conductivity

Abstract

Abstract: A series of LiAl_0.3Co_0.7-xMg_xO₂(x=0.01-0.13) powders were synthesized and characterized by XRD and TEM measurements. The results show that the crystal size is under 1 μm. When x≤0.11, the peaks in the XRD patterns are very sharp which indicate that the materials are well crystallized. After indexing the peaks, it was confirmed that the materials formed an α-NaFeO₂ structure which ensured the lithium ions pass fluently during the charge-discharge process.

Key words: LiAl_0.3Co_0.7-xMgxO₂, XRD, TEM, Electrical conductivity
