Nanocasting and Direct Synthesis Strategies for Mesoporous Carbons as Supercapacitor Electrodes

The flexible construction of electrode materials performs important functions in significantly enhancing the electrochemical properties of both energy storage and conversion devices. There is an increasing demand, not only for the current, but also the near-future energy field, where both high energy and power densities are necessary for the fabricated electrode materials. Carbon based nanoporous electrode materials demonstrate diverse superiority with respect to their application in the electrochemical capacitors (i.e., supercapacitors) industry. The striking characteristics of mesoporous carbons include abundance in raw materials, sustainability, good conductivity, excellent heat and chemical resistance, good workability, and lightweight nanostructure. Recently, various mesoporous carbons have increasingly been applied in the energy storage field because of their intrinsic open pore structure as well as high surface areas. However, the relationships between the synthesis strategies and the product struc...
