文摘

Nanosized SnSb alloy particles were pinned on the surface of micrometer-sized hard carbonspherules by a coprecipitation method in glycol solution at low temperature. Thanks to thesmall alloy particle size, good dispersion, and tight pinning of the alloy particles on thesurface of carbon, in addition to the fact that both the alloy and the carbon are active for Listorage, the composite materials as prepared show much improved electrochemical performances as anode materials for lithium ion batteries compared with alloy and carbon alone.Such a special structure effectively hinders the aggregation of nanosized alloy particles,which are the main difficulties in the application of nanoscale alloy-based anode materialsfor Li ion batteries.
