Here, we study superacid assisted exfoliation and sodium cycling behavior of TMD electrodes as potential high capacity materials for metal-ion batteries and supercapacitor electrodes. We show that sodium capacity and cycling efficiency for freestanding TMD electrodes is higher than graphite and graphene oxide electrodes reported so far. Our results also highlight the challenges associated with capacity decay and voltage hysteresis in TMDs, which become evident after only few initial cycles.
