Abstract

3D CoNi₂S₄ and cross-linked NiCo₂S₄ arrays have been grown on carbon paper (CP) using a one-step hydrothermal method. The 3D cross-linked structure provides a convenient channel for electron and lithium-ion (Li⁺) transport and performs a facile strain relaxation during cycling, exhibits high capacity, excellent rate capability and superior cycle performance.
