| Abstract | Silicon (Si) has been gaining considerable attention in the field of Li-ion batteries although unstable solid-electrolyte interphase (SEI), extreme volume changes and inferior conductivity hinder its practical application. Herein, ultrasonic-assisted electrostatic self-assembly of fluidic colloidal coprecipitation of MXene wrapped Si nanoparticles (Si@MXene) is proposed. Utilizing the natural negatively charged MXene to capture positive-charged Si nanoparticles, the homogeneous Ti3C2Tx MXene coating on Si nanoparticles prevents the nanoparticles from directly contacting the electrolyte and thus enables the formation of a stable SEI film on the composite particulates. Due to the elimination of unstable solid-electrolyte interphase on the surface of Si nanoparticles, Si@MXene delivers high capacity and excellent retention stability of 94 % after 100 cycles. The strategy demonstrated here offers the rational design of MXene-coated Si anodes with high capacity and superior cycling stability. |
