synthesis and elcetrochemical properties of (1-x)Li4/3Ti5/3O4-xLiCrTiO4 spinel structure as anode materials for Lithium secondary batteries

Abstract

In this study, the spinel (1-x)Li4/3Ti5/3O4-xLiCrTiO4 (0<x<1) were synthesized by sol-gel method. The electrochemical performance of these materials were evaluated using 2032 coin cell. spinel Li4/3Ti5/3O4 and LiCrTiO4 are exhibited a reversible capacity of approximately 163 mAh/g and 154 mAh/g with excellent cycleability in 1.2~3 V after 50 cycles, respectively
