Figure 4

(a) Galvanostatic charge/discharge voltage curves of the GNSs/Li4Ti5O12/SWCNTs hybrid electrode (G-LTO-C; G-9 layer LTO-C) at 1 C-rate and room temperature, (b) discharge (Li-insertion) capacities of G-LTO-C, the pristine Li4Ti5O12 electrode (P-LTO; 1.3 mg cm−2), and the bead-milled Li4Ti5O12 electrode (BM-LTO; 1.3 mg cm−2) during cycling with different current densities, (c) electrode discharge capacities of G-LTO-C, P-LTO and BM-LTO, (d) average discharge voltages of G-LTO-C, P-LTO and BM-LTO, (e) discharge voltage curves of G-LTO-C at different C-rates, (f) cycle performance of G-LTO-C, P-LTO and BM-LTO at 100 C-rate for 1000 cycles.
