Formation of Li10Zn4O9, Li2MoO3, and ZnSeO3 Nanophases: Roles in Electrical Conductivity and Electrochemical Stability in Lithium Ion Conductors and their Crystalline Counterparts

Abstract

Li2O doped glass-nanocomposites and their crystalline counterparts have been developed and analyzed on the light of DC conductivity and cyclic-voltammetic (CV) studies. Micro-structural study reveals the distribution of Li10Zn4O9, Li2Zn2(MoO4)3, ZnMoO4, Zn(MoO2)2, Li2Mo6O7 and Li2MoO3 nanophases in the glassy matrices. Crystalline counterparts exhibit an enhancement in crystallites’ sizes. As the crystalline counterpart is formed by controlled cooling, ZnSeO3 chain structure is expected to break by increasing dimensions of molybdate rod-like structures. In the present study, crystalline counterpart shows better electrochemical stability. Interconnected ZnSeO3 nanophases have to initiate structural stability as they play pivotal role in the formation of structure. Formation of Li10Zn4O9 and Li2MoO3 nanophases are supposed to be responsible for higher conductivity in the glassy system.
