“…Based on the atom transfer radical polymerization techniques, the PMMA‐ b ‐PAN copolymer can be transformed into microemulsion hollow spheres and highly nanoporous carbon materials after pyrolysis (Figure 12e) 207. Poly(methyl methacrylate)‐ b ‐polystyrene (PMMA‐ b ‐PS) block copolymers were also used to self‐assemble into uniform spherical micelles (Figure 12f).…”

Synthesis Strategies of Porous Carbon for Supercapacitor Applications

Supercapacitors (SCs) have experienced a significant increase in research activity and commercialization during the past few decades. As the primary and most important electrode active material for commercial SCs, porous carbon is produced at an industrial‐scale through traditional carbonization‐activation strategies. Nevertheless, commercial porous carbon materials have some disadvantages such as high production cost, corrosion of equipment, and emission of toxic gases and byproduct pollutants during production. In recent years, huge efforts have been made to develop novel synthesis strategies for porous carbon materials. This review focuses on the pore formation mechanisms in traditional carbonization‐activation methods, emerging activation methods, template methods, self‐template methods, and novel emerging methods for the synthesis of porous carbons for SCs. Strategies developed so far for the synthesis of porous carbon materials are summarized. The mechanisms and recent advances for each strategy are reviewed. Furthermore, future directions and synthesis strategies for porous carbons are proposed.

“…pore volume and size) is responsible for the ion diffusion as well as the rate performance of the supercapacitor, 28 while a high surface area contributes to a high capacitance because of its large number of accessible active sites. [36][37][38][39] Gogotsi et al developed a monolithic carbide-derived carbon, which contained micro-, meso-and macropore structures with an extremely high surface area, and showed great potential for energy storage. 14,15 All these factors help understand the fundamental role of the electrochemical interfaces at the nanoscale.…”

The volumetric performance of electrochemical energy storage (EES) devices, other than gravimetric performance, is attracting increasing attention due to the fast development of electric vehicles and smart devices. Carbon-based electrodes have advanced the fast development of EES devices while being limited by their low volumetric performance because of their porous structure and the resulting low density. This paper aims to clarify the importance of the volumetric performance and review the most recent progress on advanced EES devices with a high volumetric performance. Strategies for improving the volumetric performance, particularly with carbon-based materials are also proposed here. The transformation of normal low-density carbons to high-density ones through the assembly of different building blocks is highlighted as a promising remedy for this issue, and their applications in next-generation EES devices (Li-S, Li-air, Na-ion, etc.) are also discussed.

“…The electric double-layer capacitance comes from pure electrostatic attraction between ions in an electrolyte and the charged surface of an electrode, such as carbon materials, which are not electrochemically active [6][7][8][9]. As a result, high power density can be obtained, but energy density is relatively low, which limits the practical application of EDLCs.…”
