The typical CV curves for (a) the LT-LiCoO2 nanowire arrays and (b) the HT-LiCoO2 nanowire arrays between 3 and 4.2 V at a scan rate of 0.1 mV s−1. The initial two cycle charge/discharge curves for (c) the LT-LiCoO2 nanowire arrays and (d) the HT-LiCoO2 nanowire arrays between 3 and 4.2 V at 0.1C rate. (e) Comparison of cycle performance between the LT-LiCoO2 and HT-LiCoO2 nanowire arrays. (f) Rate performance of the HT-LiCoO2 nanowire arrays (inset is the Nyquist plot for the LT-LiCoO2 and HT-LiCoO2 nanowire arrays).
