Electrochemical analysis of NiSiNWs@GrμT. a CV profiles of NiSiNWs@GrμT during sweeps over the range from 2.0 to 0.0 V vs. Li/Li+ at a rate of 0.1 mV s−1. b Galvanostatic charge-discharge profiles of NiSiNWs@GrμT for the 1st, 10th, 20th, and 100th cycles. c Capacity of NiSiNWs@GrμT cycled at the discharging rate while undergoing stepwise changes from 1C to 20C. The NiSiNWs-on-NiF is used for comparison (black). d Discharge capacity (solid circles) and coulombic efficiency (open circles) of NiSiNWs@GrμT at 10C (black) and 20C (red) for 2000 cycles. The same plots of NiSiNWs-on-NiF at 2C (blue). e Rate capability test of NiSiNWs@GrμT with various cycling rates from 1C to 80C. All tests were performed using 1.0 M LiPF6 in EC/DEC (1:1) as the electrolyte, in the potential window between 0.0 V and 2.0 V (vs. Li/Li+). All the capacities are represented based on the weight of NiSiNWs
