Porous carbon materials are potential materials for lithium-ion battery electrodes due to their structural advantages such as large specific surface area, high physical and chemical stability, and good conductivity. Porous carbon materials show excellent reversible specific capacity and cyclability. The main advantage of porous electrodes is that they have a much larger reaction surface than flat electrodes, which is conducive to the electrochemical reaction.
