title: A novel Co-Li2O@Si core-shell nanowire array composite as a high-performance lithium-ion battery anode material.
abstract: We report a novel material of Co-Li2O@Si core-shell nanowire array synthesized via the lithiation of pre-synthesized CoO@Si core-shell nanowire arrays during the first cycle. When the potential window versus lithium was controlled between 0.01-1.2 V, the coated Si shell could be electrochemically active, while the Co-Li2O nanowire core could function as a stable mechanical support and an efficient electron conducting pathway during the charge-discharge process. The Co-Li2O@Si core-shell nanowire array anodes exhibit good cyclic stability and high power capability compared to planar Si film electrodes.
