Background

Energy storage applications need advanced anode materials to replace graphite for improved charge storage capacity and performance. Nickel sulfide (Ni₃S₂)-filled carbon nanotubes (CNTs) have been proposed as an anode material that is a good metallic conductor for improved capacity and enhanced ion conduction due to nanostructuring of the material. Although bulk electrochemical testing has demonstrated good performance of these anodes for lithium cycling, the lithiation and deformation mechanisms are not well understood.
