摘要：
Sn@Ni3Sn4 embedded nanocable-like carbon hybrids have been successfully prepared through a novel gas-phase route. The introduced Ni3Sn4 layer not only suppresses the tin-induced volume expansion, but also provides more voids and vacancies in the interior of the nanocables. When used as the anode in LIBs, the Sn@Ni3Sn4/C hybrids exhibit a long cycle life (360 mA h g(-1) at 1 A g(-1) after 1500 cycles).
