Electrochemical characterization of Cu/LTO scaffold: (a) Cycling performance and corresponding efficiency of Cu/LTO hybrids at the rate of 0.5 C. (b) The galvanostatic discharge/charge voltage profiles of Cu/LTO at 0.5 C in the 1st, 50th, 100th, 600th and 1200th cycles. (c) Comparison of the rate capabilities of Cu/LTO and LTO NPs. (d) The cycling performance and corresponding Coulombic efficiency of Cu/LTO at 1 C. (e) Comparison of the rate capability of Cu/LTO scaffolds with other recently reported LTO-based high rate electrodes. The capacities were estimated based on their total mass of electrode materials.
