▎ 摘 要
Nanoporous networks of tin-based alloys immobilized within carbon matrices possess unique structural and compositional superiorities toward lithium-storage, and are expected to manifest improved strain accommodation and charge-transport capabilities and thus desirable anodic performance for advanced lithium-ion batteries (LIBs). Herein, a facile and scalable hybrid aerogel-derived thermal-autoreduction route has been developed for the construction of nanoporous network of Sn-Ni alloy immobilized within carbon/graphene dual matrices (Sn-Ni@C/G network). When applied as an anode material for LIBs, the Sn-Ni@C/G network manifests desirable lithium-storage performances in terms of specific capacities, cycle life, and rate capability. The facile aerogel-derived route and desirable Li-storage performance of the Sn-Ni@C/G network facilitate its practical application as a high-capacity, long-life, and high-rate anode material for advanced LIBs.
