Contact-Engineered and Void-Involved Silicon/Carbon Nanohybrids as Lithium-Ion-Battery Anodes



original image

A novel anode structure composed of silicon nanowires dwelling in graphitic tubes is developed. The thus-fabricated 1D/1D hybrid structure exhibits good rate capability and remarkable cycling stability, which mainly originates from their structural advantages including the built-in void spaces and the robust line-to-line contact mode between the components.
