In Situ
Growth of MOFs on the Surface of Si Nanoparticles
for Highly Efficient Lithium Storage: Si@MOF Nanocomposites as Anode
Materials for Lithium-Ion Batteries
A simple
yet powerful one-pot strategy is developed to prepare
metal–organic framework-coated silicon nanoparticles via in
situ mechanochemical synthesis. After simple pyrolysis, the thus-obtained
composite shows exceptional electrochemical properties with a lithium
storage capacity up to 1050 mA h g<sup>–1</sup>, excellent
cycle stability (>99% capacity retention after 500 cycles) and
outstanding
rate performance. These characteristics, combined with their high
stability and ease of fabrication, make such Si@MOF nanocomposites
ideal alternative candidates as high-energy anode materials in lithium-ion
batteries
