通过简便、低成本的合成工艺实现高功率锂离子混合电化学电容器(Li-HEC)仍是一项具有挑战性的工作。本论文以常用的食品添加剂为原料，通过柠檬酸镁的简单热解和NH3的处理制备了掺氮多孔碳(N-HPC)，并通过柠檬酸铁热分解和空气中的热处理分别制备了碳包覆的Fe2O3(Fe2O3@C)。分别以N-HPC和Fe_2O_3@C为正负极材料制备了一种高功率材料，在368W/kg−1和31W/kg−1的高能量密度下分别达到65W/kg−1和31W/kg−1的高功率密度，并且在1 A/g−1下在1000次恒流充放电循环中保持84.1%的容量。
Achieving high-power lithium-ion hybrid electrochemical capacitor (Li-HEC) through facile and low-cost synthesis procedures is still quite challenging. In this work, starting from daily used food additives, nitrogen-doped hierarchical porous carbon (N-HPC) was prepared through facile pyrolysis of magnesium citrate and subsequent NH3treatment, and carbon-coated Fe2O3(Fe2O3@C) was synthesized by thermal decomposition of ferric citrate and following heat treatment in air, respectively. As-prepared N-HPC and Fe2O3@C were separately employed as cathode and anode materials to fabricate a high-power, which delivers a high energy density of 65 W h kg−1at 368 W kg−1, and 31 W h kg−1at a high power density of 9.2 kW kg−1. And it remains 84.1% capacity over 1000 galvanostatic charge-discharge cycles at 1 A g−1.
