Electrochemical Properties of Fe sub(2)O sub(3)/Ga sub(2)O sub(3) Composite Electrodes for Lithium-Ion Batteries

Fe sub(2)O sub(3)/Ga sub(2)O sub(3) composite and GaFeO sub(3) 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...

Zusammenfassung:Fe sub(2)O sub(3)/Ga sub(2)O sub(3) composite and GaFeO sub(3) 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 Fe sub(2)O sub(3)/Ga sub(2)O sub(3) composite and 1196 mAh/g for GaFeO sub(3), respectively. Despite same Fe/Ga atomic ratio, Fe sub(2)O sub(3)/Ga sub(2)O sub(3) composite showed a higher capacity than that of GaFeO sub(3) over the 50 cycles.
