A high interconnection yield prevents Si nanowires from detaching from their substrate, resulting in improved cycling stability. Si-nanowire-based anodes exhibit a 100% charge retention after 40 cycles at C/2 rate. They can be cycled at a rate of 8C without damage. A Si load of 1.2 mg/cm2, corresponding to a charge density of 4.2 mAh/cm2 is reported for the anode.
