High Power In-Plane Micro-Supercapacitors Based on Mesoporous Polyaniline Patterned Graphene.
Micro-supercapacitors (MSCs) based on mesoporous polyaniline patterned graphene are demonstrated. The synergic effect from both electron-double-layer-capacitive graphene and pseudocapacitive mesoporous-polyaniline leads to outstanding MSC device performances, in regard to excellent volumetric capacitance and rate capabilities, which further result in a high power density of 600 W cm-3, suggesting opportunities for future portable and wearable power supplies in diverse applications.
