Abstract

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 NH₃ treatment, 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⁻¹ at 368 W kg⁻¹, and 31 W h kg⁻¹ at 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.
