A designed hierarchical nanostructure consisting of SnS nanosheets and ultrathin MoS2 nanosheets was achieved, and then evaluated as anode material for LIBs with high capacity and long cycle life.
High-capacity Si-based anodes with good coulombic efficiency and long-cycle life are achieved by embedding silicon nanoparticles in dual Ni3Sn4/Ni3Sn2 active/inactive intermetallic matrix.
