摘要
为提高电极材料性能,采用微乳液法与溶剂热法相结合制备了Fe_(3)O_(4)颗粒,进而制得了Fe_(3)O_(4)电极材料,并研究了反应温度、煅烧处理对电极材料电容性能的影响。结果表明,当反应温度为140℃时所制得的电极材料的电容性能优于120℃、160℃时制得电极材料的电容性能;煅烧处理对电极材料的电容性能有促进作用,在140℃下制得的电极材料经煅烧处理后的电容性能仍最佳,在电流密度分别为1,2,5 A/g时,比电容分别提升至420.5,230.0,142.5 F/g。
In order to improve the capacitance of electrode materials,ferroferric oxide particles for making Fe_(3)O_(4) electrode material were prepared by microemulsion method combining solvothermal method,and the effects of reaction temperature and calcination on the capacitance properties were studied.Results showed the capacitance of electrode materials prepared at 140℃was much better than the ones prepared at 120℃and 160℃.Calcination was proved to be beneficial for the capacitance performance of the ferroferric oxide electrode.The electrode obtained at the reaction temperature of 140℃with subsequent calcination sustained better capacitance performances.When the current density was 1,2,5 A/g,the specific capacitance could reach 420.5,230.0,142.5 F/g,respectively.
