Abstract
In this research, Fe 2O 3 nanorod arrays grown on carbon fiber paper were studied, and carbon-coated Fe 2O 3 (Fe 2O 3 @C) and sulfurized Fe 2O 3 @C (Fe 2O 3 @C-S) were fabricated by carbon coating and sulfurization processes. To promote the application of these materials in supercapacitors, their electrochemical properties were systematically investigated. Based on the results, the materials obtained utilized a pseudocapacitive mechanism for energy storage. Specifically, Fe 2O 3 exhibited a moderate specific capacitance and extraordinary cycling stability, and no degradation was observed after 10,000 cycles. Impressively, sulfurization greatly enhanced the rate capability and specific capacitance of the sample. As a result, Fe 2O 3 @C-S attained a specific capacitance of 976.4 mF cm –2 at 4 mA cm –2 and a robust rate capability of 97.30% at 20 mA cm –2, outperforming Fe 2O 3 @C (84.39%) and Fe 2O 3 (70.55%) and demonstrating good cycling stability (92.9%). Notably, Fe 2O 3 @C-S was active as a positive electrode material; thus, a symmetric supercapacitor was assembled, which yielded a volumetric energy density of 1.46 mWh cm –3 at 16.71 mW cm –3 and maintained an energy density of 0.91 mWh cm –3 even at 145.63 mW cm –3. Moreover, the device exhibited good cycling stability with a capacity retention of 88.3% after 10,000 cycles at 10 mA cm –2. The integration of Fe 2O 3 nanorod arrays on conductive substrates, coupled with the above modifications, strongly promoted the material’s energy storage performance. Our study emphasized the significant potential of Fe 2O 3 @C-S as an efficient electrode material for supercapacitors.
