The rapid development of microelectronic devices has stimulated an increasing demand for micro-energy storage devices, typically, micro-supercapacitors (MSCs). Despite recent advances, the fabrication of MSCs using a facile, scalable and inexpensive method still remains challenging. In this work, we use a facile screen printing technique to fabricate flexible all-solid-state MSCs using N-doped reduced graphene oxide (rGO) as the electrode material. The effective area of MSCs and the thickness of the active material are only 0.396 cm(2) and 10 mu m, respectively. The MSCs can deliver a high specific areal capacitance of 3.4 mF cm(-2), which is among the high values of graphene-based materials for all-solid-state MSCs reported so far Easy fabrication and good performance make MSCs promising on-chip energy storage devices.
