                 Abstract: To obtain electrode materials with high performance of supercapacitor, porous graphite carbon
                 with high nitrogen level (NPGC) was prepared via a novel aggregation-NaOH activation route, in which
                 low-cost kelp and melamine severed as carbon and nitrogen source, respectively. The as-prepared samples
                 were characterized by XRD, BET, Raman and XPS. The results showed that the resulting NPGC with a
                                                                 2
                 lamellar structure displayed a large surface area of 1771 m /g and a high graphite degree (I D/I G=2.84) and
                 possessed a high nitrogen content of 6.27 atomic percentage. In addition, the electrochemical properties of
                 the samples were examined  using cyclic voltammetry (CV), galvanostatic charge-discharge  (GCD)  and
                 electrochemical impedance spectroscopy (EIS). As a result, the specific capacitance of the NPGC material
                 reached up to 267 F/g at 1 A/g. Furthermore, the specific capacitance of the sample was still 99.9% of the
                 initial specific capacitance after 5000 cycles. Thus, the synthesized material had excellent energy storage
                 properties.
