We report a two-step, solution-based method for the fabrication of 3D ZnCo2O4/NiO core/shell nanowire arrays that can be applied in Li-ion batteries.
Novel core–shell structured Si/S-doped carbon composite with buffering voids prepared by hydrothermal method and followed by carbonization and removal of template layer, exhibiting a reversible capacity of 664 mA h g−1 over 300 cycles.
