XRD Analysis of Li4Ti5O12 with Post Heat Treatment for Lithium-ion Capacitor (LIC) Applications

Abstract

Characterization of XRD-analysis on Li4Ti5O12 with post heat treatment for applications Lithium-ion Capacitor (LIC) has been conducted. The powder method was used in the analysis, whereas the samples were prepared using the sol-gel method. The anode material Li4Ti5O12 precursor was sintered at 850°C for 4 hours and followed by heat-treatment at 600oC for 3 hours. Characterization of structural (XRD analysis) was applied to determine the formation of Li4Ti5O12 phase. The results of the characterization were formed Lithium titanate (Li4Ti5O12) and rutile phase (TiO2) with crystallite size on LTO I of 82.52 nm and LTO II of 92.07 nm. Overall, post heat treatment of anode Li4Ti5O12 succeeded in improving the quality and electrochemical performance for Lithium-ion Capacitor (LIC) application.
