摘要
通过二次水热法,以泡沫镍为集流体,原位生长铁掺杂镍钴碲化物做为超级电容器的正极材料。以Fe∶Ni=1∶100为1%掺杂量,通过三氯化铁提供铁元素,系统的研究了不同铁掺杂量对镍钴碲化物的组织、形貌和电化学性能影响,研究表明,当铁掺杂量为6%时所制备的铁掺杂镍钴碲化物电极材料具有最优的电化学性能,在1A/g的电流密度下比电容可达到214F/g,且具有良好的倍率性能和结构稳定性。
Fe-doped Ni-Co telluride was grown in-situ as anode material of supercapacitor by secondary hydrothermal method using nickel foam as current collector.Using Fe:Ni=1:100 as the doping amount of 1%,and iron element provided by ferric trichloride,the effects of different iron doping amounts on the structure,morphology and electrochemical properties of nickel-cobalt telluride were systematically studied.The research showed that when the iron doping amount was 6%,the iron-doped nickel-cobalt telluride electrode material prepared had the best electrochemical properties,the specific capacitance can reach 214 F/g at a current density of 1 A/g,and hadd good rate performance and structural stability.
