Supercapacitor charge-discharge process

Hierarchical porous graphene/polyaniline composite film with a superior rate performance for supercapacitors was fabricated by chemical polymerization method. This composite exhibited 385 F/g at a current density of 0.5 A/g, with a capacity retention of 94% as current density was varied from 0.5 to 10 A/g. This superior rate performance was demonstrated to be due to the interconnected porous structure of the film, which allowed electrolyte ions to pass through quickly during the rapid charge-discharge process [62].
