Effect of Lithium Pre-doping on Electrochemical Properties of Fe2O3/Graphites Nanocomposites as Lithium Ion Capacitor Negative Electrodes |
| 초록 |
In this study, Fe2O3/expanded graphites (EGs) nanocomposites were prepared by loading Fe2O3 on surfaces of graphites for lithium ion capacitors (LICs). Although the metal oxide composite as negative electrode materials suffered from poor cyclic performance, in order to reduce this problem both Fe2O3 nano-sizing and lithium pre-doping method were carried out. The electrochemical tests indicated that these composite electrodes could deliver a higher discharge capacity and cyclic retention. Consequently, the improvement of reversible capacity and cyclic performance of the lithium pre-doped Fe2O3/EGs composites could be attributed to the combination between the nano-sized Fe2O3 and the network of graphites. |
