(a) Charge-discharge curves of MoS₂/GO composites at current density of 100 mAg⁻¹; (b) Representative cyclic voltammograms of MoS₂/GO composite at the first 3 cycles between 0.01 V and 3.0 V at scan rate of 0.1 mV s⁻¹; (c) The cycling performance of MoS₂/GO composite at various current densities of 1 A g⁻¹ and 2 A g⁻¹ (d) Nyquist plots of MoS₂/GO composite and MoS₂:GO powder blended electrode after 10 discharge/charge activation cycles. Inset shows the equivalent circuit model used for the fittings and the corresponding values are shown in Table 1. (e) Schematic illustration of the surface structure of MoS₂/GO composite for high current density lithium storage.
