Li2+xMnSi1−xAlxO4/C nanoparticles for high capacity lithium-ion battery cathode applications

Abstract

Li2+xMnSi1−xAlxO4/C (0 < x < 0.09) nanoparticles were synthesized under supercritical fluid conditions at 550 °C for 3 h using water and ethanol as mixed solvent. Compared with Li2MnSiO4, Li2+xMnSi1−xAlxO4 displays higher theoretical capacity and better electrochemical properties. Li2.09MnSi0.91Al0.09O4/C nanoparticles with an average diameter of ca. 11 nm deliver a high discharge capacity of 308 mA h g−1, which indicates an approximate two Li+ ion exchange can be realized during the cycling process.
