Summary: This study proposed a spatial control strategy using lotus-root-like Ni-Co hollow prisms@carbon fibers as the host to address the challenges of lithium dendrites growth and huge volume change for practical applications of Li-metal anodes. The homogeneous distribution of bimetallic Ni-Co particles and the 3D conductive network effectively reduced the overpotential for Li nucleation and guided uniform Li nucleation and non-dendritic growth. As a result, the NCH@CFs host enabled a stable Li metal anode with low voltage hysteresis during repeated Li plating/stripping.
