| 英文摘要 | Mass/charge transfer properties of the electrode material in vanadium redox flow battery (VRFB) has a direct influence on battery performance, especially for the negative reaction with kinetic lag and synchronous hydrogen evolution side reaction. In our previous work, the mass transfer performance of electrospun carbon nanofibers electrodes is effectively improved by using the spherical-filament binary materials (SCMS-ECNFs). In this work, Sn-based catalyst functionalized carbon microspheres with suitable size are constructed by a two-step hydrothermal method, which are then introduced into the precursor solution of electrospinning. After electrospinning and subsequent pre-oxidation and carbonization, Sn functionalized carbon microspheres-carbon nanofibers (Sn@SCMS-ECNFs) ternary composite electrode can be successfully constructed. The Sn@SCMS-ECNFs electrode possesses better mass transfer performance than the traditional ECNFs due to the support effect of Sn@SCMS, and exhibits better activity to the lagging negative reaction due to the anchoring effect of tin-based catalyst, which is expected to be a new type of high performance electrode material for VRFBs. The asymmetry VRFB single cell with Sn@SCMS-ECNFs ternary composite material as the negative electrode and SCMS-ECNFs binary composite material as the positive electrode shows lower polarization overpotential and larger capacity (15 % increased) than the symmetry VRFB with SCMS-ECNFs as both negative and positive electrode. Besides, the energy efficiency is 81.1 % at 200 mA center dot cm-2, 1.7 % higher than the symmetry VRFB above, suggesting the feasibility of this ternary composite electrode in further improving the battery performance. |
