摘要
Fe2O3/Ga2O3 composite and GaFeO3 electrodes worked as rechargeable electrode materials for lithium-ion batteries, whereas their capacities were gradually decreased with increasing of cycle number. The initial Li insertion capacities (cut-off voltage: 0.01 V) were 1643 mAh/g for Fe2O3/Ga2O3 composite and 1196 mAh/g for GaFeO3, respectively. Despite same Fe/Ga atomic ratio, Fe2O3/Ga2O3 composite showed a higher capacity than that of GaFeO3 over the 50 cycles.
