Preparation of Li4GeO4–Li3VO4 based electrolytes via mechanochemical treatment
Source abstract
Abstract
Pseudo-binary electrolytes of (100 − x)Li4GeO4·xLi3VO4 (x = 0, 10, 20, 30, 40, and 50 mol %) and pseudo-ternary electrolytes of 45Li4GeO4·45Li3VO4·10LiaMOb (M = B, Si, P, S, Mo, and W) with lithium superionic conductor (LISICON) type structures were prepared by mechanochemical treatment and subsequent heat treatment. For the (100 − x)Li4GeO4·xLi3VO4 heated samples with LISICON-type structure, the activation energy decreased with increasing Li3VO4 content, and the x = 50 sample showed a high conductivity of 1.1 × 10−4 S cm−1 at 25 °C. The 45Li4GeO4·45Li3VO4·10LiaMOb heated samples with LISICON-type structure showed a conductivity of approximately 10−5 S cm−1 at 25 °C, and the larger “a” as the Li content in Lia(Ge0.45M0.1V0.45)Ob contributed to improving the ionic conduction properties of this system.
