Hierarchical design of porous carbon materials for supercapacitors
, 2014 This chapter discusses the mechanisms of charge storage by electrostatic processes and ion transport in the porous texture. The roles of the carbon structures, such as basal/edge planes, pore size, surface area, pore tortuosity, pore regularity, and the surface wettability of pores, are discussed.
