Abstract

A unique sandwich structure Fe₃O₄@C@MoSe₂ architecture is proposed for high-performance lithium storage. Carbon shell as the connection of in/external structures can not only improve the overall conductivity but also alleviate the volume expansion of Fe₃O₄ and avoid the aggregation of MoSe₂ nanosheets. Moreover, MoSe₂ nanosheets on carbon shell demonstrate enlarged interlayer spacing, which can accelerate the kinetics of Li⁺, and thus improve the rate performance.
