Figure 4

(a) First-cycle discharge curves of the (a) LVO NPs-GNs and (b) LVO NPs electrodes. (b) Left axis: Cycling performance of the electrodes: (a) LVO NPs-GNs and (b) LVO NPs electrodes. The electrodes were charged-discharged between 1.5 and 4 V (vs. Li/Li+) at current densities of 0.1 A g−1 (1C = 0.3 A g−1); Right axis: Coulombic efficiency of the LVO NPs-GNs electrode. (c) Rate-performance of the electrodes: (a) LVO NPs-GNs and (b) LVO NPs. (d) Nyquist plots of the electrodes of (a) LVO NPs-GNs and (b) LVO NPs.
