Micro-supercapacitors (MSCs) are attractive for applications in next-generation mobile and wearable. However, many previous MSCs have often exhibited a low volumetric energy density because of the non-uniform pore structure of the electrodes. To address this issue, we to fabricate 3D sub-micrometer pore-patterned carbon film. Furthermore, a hierarchical pore-patterned carbon (hPC) electrode was formed by introducing a micropore by chemical etching. The hPC electrodes were applied to solid-state MSCs. We achieved a constant volumetric capacitance and a corresponding volumetric energy density for electrodes of various thicknesses. |
