Preparation of PtAu catalytic particles on positive electrode of Li/air battery using pulse electroplating
To decline the usage of noble metals on air electrode,pulse electrodeposition technology was used to prepare the PtAu catalyst.By Cyclic Voltammograms (CV) test,Scanning Electron Microscopy (SEM) and Energy Dispersive Spectrometer (EDS),the optimized bath composition and deposition process were determined as followed:HAuCl4 of 13.3 mmol/L,H2PtCl6 of 6.7 mmol/L,H2SO4 of 0.5mol/L,peak current density of 100mA/cm2,pulse width of 5% and frequency of 1kHz.The PtAu catalysts that were prepared under the optimized process distributed on air electrode uniformly with particle sizes of 200~300nm and caused the discharge specific capacity of Li/air battery reaching up to 1300mAh/gcarbon+PVDF that was more than two times of that without catalyst.
