摘要：
The effects of current collectors on the electrochemical performance of FeS2 electrode have been investigated by applying three types of current collectors, including an Al foil, a Cu foil and a Ni foil. The results show that Ni current collector can greatly improve the discharge capacity and cycle ability of FeS2 electrode compared to the Al current collector. Cyclic voltammetry and electrochemical impedance spectroscopy also show that the electrodes on the Ni foil show much smaller polarization and lower impedance. Although Cu foil is utilize...
