Supercapacitors have become attractive energy storage devices due to their high power density, good cycling stability, and fast charging and discharging speeds. Porous carbon has great specific surface area, high energy density and good conversion performance, so porous carbon as supercapacitor electrode material has been widely concerned. Carbon materials with different dimensions and sizes, such as porous carbon spheres, porous carbon nanotubes (CNTs), porous carbon nanofibers (CNFs) porous graphene (GR) and activated carbon (AC) can provide different performance advantages. At the same time, the composite of porous carbon with metal compounds, conductive polymers and particles containing N/P/O/S can further optimize electrode materials, as well as the significant effects on the increase of specific surface area and energy density are obtained. This article introduces the porous carbon materials used as electrode materials in recent years, as well as their multi-level structural materials and related composite materials. We first introduced porous carbon electrode materials with different dimensions and compared their electrochemical performance. Then, based on various research results, the factors affecting its electrochemical performance were discussed in detail. As well as, the preparation methods of porous carbon electrode materials were introduced, and the specific requirements, advantages and disadvantages of different preparation methods were briefly analyzed. The application of porous carbon electrode materials combined with other materials in supercapacitors is listed. Finally, a summary and outlook of the current research status were supplied, providing reference for the rational design of porous carbon supercapacitors in the future.

In this study, N-doped graphene oxide-polypyrrole-silica (NGO-PPy-SiO2) composite was employed as a possible anode in Li-ion batteries. The chronoamperometric technique was employed to synthesize NGO, and within this study two samples were produced, one characterized by a high polypyrrle content (N1) and the other by a low polypyrrle content (N2). N2 has the maximum initial discharge capacity of 785 mAh/g at 0.1C, which is greater than N1's capacity of 501 mAh/g. The initial coulombic efficiency of the first cycle is around 72%, whereas the ICE of N2 is approximately 60%. N1 demonstrates outstanding cycling performance for 100 cycles at high rate (10 C) with maintain capacity as 100% and coulombic efficiency of 100%, as well as extremely stable capacity during the cycling. N2 has a maintain capacity of ≈ 79% and excellent coulombic efficiency, however the capacity during cycling is not as stable as N1.

Poly(3,4‐ethylene dioxythiophene) (PEDOT) is a conducting polymer that can be used in flexible bioelectronic devices. The electrode/electrolyte interface interaction is one of the most important factors in improving the electrochemical performance of energy storage materials, and these polymers are often combined with a negatively charged poly(styrene sulfonate) (PSS) chain to improve their interaction with alkali metal cations such as sodium and potassium. In this work, we performed a one‐step electrochemical synthesis of PEDOT on carbon fabric using the molecule 2‐acrylamido‐2‐methyl‐1‐propane sulfonic acid (AMPS) to create highly effective materials for supercapacitor electrodes. The electrode had a significant increase in capacitance value, measured 16.4 times higher than that of the PEDOT electrode. The 2‐electrode system exhibited a specific capacitance value of 495.2 F g−1 at a scan rate of 5 mV s−1. It exhibited a high operating voltage of 2.3 V in aqueous electrolyte system. It showed a significant energy density of 109.0 Wh kg−1 when operating at 6.1 kW kg−1 power density and 85.2 Wh kg−1 when operating at 30.6 kW kg−1 power density. Recent findings reveal that the capacitance retention performance value of the device increased significantly to 113.9% after 25,000 cycles in 3.0 M NaCl aqueous electrolyte, demonstrating its outstanding long‐term durability. Thus, the creation of the synthesized supercapacitor electrode is a significant advance in the study of conducting polymers, which often have a limited lifetime in real‐world electronic applications.
