The prepared MnO 2 with a nanowire structure had a high specific surface area and narrow pore distribution, which was very useful for gel-type electrolyte in supercapacitor applications. The specific capacitance of nanowire-structured MnO 2 with PAAK electrolyte exceeded 484 F g -1 at the conventional loading weight of MnO 2 (1.02 mg cm -2) in the electrode. The nanowire-structured MnO 2 with PAAK electrolytes was a very promising electrode material for high-performance supercapacitors. ? 2012 The Electrochemical Society. |
