title: Freeze-dried MoS2sponge electrodes for enhanced electrochemical energy storage.
abstract: In the present study, we have synthesized high surface area MoS2sponge electrodes via a facile hydrothermal method followed by a freeze drying process. The performance of the MoS2based symmetric capacitor showed a high specific capacitance value of around 128 F g-1at a scan rate of 2 mV s-1, and also a single electrode showed a specific capacitance of 510 F g-1, which is a remarkable value to be reported for a MoS2based material in a symmetric device configuration. Also, a high energy density of around 6.15 Wh kg-1and a good cyclic stability over 4000 cycles are obtained for the symmetrical cell.
