What is Ultrafast Sodium Intercalation Pseudocapacitance in MoS~2~ Facilitated by Phase Transition Suppression about?
Sodium-ion intercalation pseudocapacitance promises fast energy storage that is cheaper than lithium-ion-based systems. MoS 2 is an attractive sodium-ion host due to its large van der Waals gaps, high Na + mobility, and high electronic conductivity in the 1T phase. In this paper, we have quantified high levels (>90%) of pseudocapacitive charge storage in 30 μm thick MoS 2 nanocrystal-based composite electrodes, which can be charged to almost 50% of their 1C capacity in just under 40 s. In addition, very little decay is observed in the delivered capacity (retention of 97%) after 1800 cycles at a rate of 20C. Synchrotron-based operando X-ray diffraction shows that the pseudocapacitive performance is enabled through suppression of the trigonal 1T-MoS 2 to triclinic Na x MoS 2 phase transition in MoS 2 nanocrystals during charge-discharge.
