Abstract

In this work, a composition of Co₃O₄ and Ag with nanocubic morphology and core-shell structure was designed and successfully prepared based on the crystal growth properties of cobalt hexacyanocobaltate and the Kirkendall effect of nanomaterials. This method has a facile preparation process. Due to the ultrathin diameter of the silver particles, the amount of raw material required is small, so it does not result in additional cost. With the excellent electrical conductivity of silver nanoparticles and the buffering properties of the hollow structure, this material can be used as an anode material for lithiumion batteries with superior cycle life and multiplicity performance than Co₃O₄ nanoparticles alone. After 50 times of charging and discharging at a current density of 1 A·g^-1, the discharge capacity still reaches 1089 mAh·g^-1, which is significantly higher than that of the graphite anode currently used in the Li-ion battery industry.
