Electrochemical characterizations of Si-based half-cells.
(a, b) Voltage profiles of as-prepared Si NWs-carbon textiles electrodes between 0.01–3.0 V at rates of 0.2 C and 1 C. (c) Cycling performance of these electrodes at 0.2 C and their corresponding coulombic efficiency. (d) The rate capability of these electrodes cycled at rates of 1 C and 4 C for as high as 200 cycles.
