34 s discharge) up to 90 mAh g -1 in comparison to MoS2 TU (50 mAh g -1 ) and MoS2 Comm (25 mAh g -1 ). Long term cycling reveals that the samples with high specific surface area and small secondary particle size show slightly better stability over 1,000 cycles, possibly due to smaller volumetric expansion of the electrode material during the first cycles revealed during dilatometric studies.
