Freeze-dried MoS2 sponge electrodes for enhanced electrochemical energy storage

Author affiliations

Abstract

In the present study, we have synthesized high surface area MoS2 sponge electrodes via a facile hydrothermal method followed by a freeze drying process. The performance of the MoS2 based symmetric capacitor showed a high specific capacitance value of around 128 F g−1 at 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 MoS2 based material in a symmetric device configuration. Also, a high energy density of around 6.15 Wh kg−1 and a good cyclic stability over 4000 cycles are obtained for the symmetrical cell.
