超级电容器用氮/氧共掺杂多孔碳纳米材料的制备及性能研究

Preparation and properties of nitrogen/oxygen co-doped porous carbon nanomaterials for supercapacitors

超级电容器作为一种新型的储能装置,而电极是决定超级电容器电化学性能的核心部件。在研究工作中,利用D-无水葡萄糖为碳源、三聚氰胺为氮源和NaHCO3为致孔剂成功合成了一种氮/氧共掺杂碳纳米材料用于高性能超级电容器。在电流密度为1 Ag-1时,电极材料的比电容可达165 Fg-1(6 M KOH电解液)。采用合成方法可以成功实现整个合成制备工艺过程中的无醛化,为电极材料的制备开辟了一条新型绿色的道路。

As a new type of energy storage device,the electrode is the core component that determines the electrochemical performance of the supercapacitors.In our research,a nitrogen/oxygen co-doped carbon nanomaterial was successfully synthesized for high-performance supercapacitors using D-anhydroglucose as the carbon source,melamine as the nitrogen source and NaHCO3 as the porogen.When the current density is 1 Ag-1,the specific capacitance of the electrode material can reach 165 Fg-1(in 6 M KOH electrolyte).The use of our synthesis method can successfully achieve the formaldehyde-free process in the entire synthesis preparation process,opening a new green road for the preparation of electrode materials.
