| Abstract: | Three types of transition metal oxide/carbon composites including Fe2O3/C, NiO/C and CuO/Cu2O/C synthesized via spray pyrolysis were used as anode for lithium ion battery application in conjunction with two types of
ionic liquid: 1 M LiN(SO2CF3)2 (LiTFSI) in 1-ethyl-3-methyl-imidazolium bis(fluorosulfonlyl)imide (EMI-FSI) or 1-methyl-1-propylpyrrolidinium bis(fluorosulfonyl)imide
(Py13-FSI). From the electrochemical measurements, the composite electrodes using Py13-FSI as electrolyte show much better
electrochemical performance than those using EMI-FSI as electrolyte in terms of reversibility. The Fe2O3/C composite shows the highest specific capacity and the best capacity retention (425 mAh g−1) under a current density of 50 mA g−1 for up to 50 cycles, as compared with the NiO/C and CuO/Cu2O/C composites. The present research demonstrates that Py13-FSI could be used as an electrolyte for transition metal oxides
in lithium-ion batteries. |
