Inactive Al3+-doped La(CoCrFeMnNiAlx)1/(5+x)O3 high-entropy perovskite oxides as high performance supercapacitor electrodes
文献摘要：
A series of high-entropy perovskite oxides(HEPOs)La(CoCrFeMnNiAlx)1/(5+x)O3-δ(x=0.4,0.5,0.6,and 0.7)have been synthesized by coprecipitation method combined with calcination process and explored as electrodes for supercapacitors.The crystal structure,microstructure,and elemental composition of HEPOs were investigated by X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),and energy-dispersive X-ray spectroscopy(EDS)in detail.The electrochemical properties of HEPOs as supercapacitor electrodes were elucidated.The specific capacitances of HEPOs(x=0.4,0.5,0.6,and 0.7)are 281.84,353.65,325.60,and 259.30 F/g at the current density of 1 A/g,respectively.After 2000 cycles,the specific capacitances of HEPOs(x=0.4,0.5,0.6,and 0.7)remain 85.01％,88.61％,86.37％,and 91.25％,respectively.Such outstanding electrochemical properties can be attributed to the entropy-stabilized structure caused by mixed six cations in B-site and the Al3+-doping suppressing active ion aggregation during charge-discharge process.This research highlights the potential of HEPOs as electrodes for supercapacitors.
