ABSTRACT: Sn/Sb based alloy anodes
have attracted considerable interest as electrodes for next-generation high
performance Li-ion batteries (LIBs) owing to their high theoretical capacities.
And fabricate porous structure is an effective way to improve materials’ cycling performance. Here, we developed nanoporous SnSb alloy ribbon (NP-SnSb) through a melt-spinning/chemical-etching process
and took it as electrode of LIB directly. Being of self-supported and binder
free, the NP-SnSb shows a total outperformance over its nonporous counterparts
both in cycling performance and kinetic characteristic. Besides, considering
the melt-spinning/chemical-etching synthetic process is high-through-put and simple, the ribbon kind of alloy anodes have
strong potential application for LIBs research.
