摘要：
Clew-like microshperes, composed of ZnCo2O4 nanoparticles, are synthesized by heat treatment of co precipitated Zn and Co contained precursor at 600 degrees C. As anode for Li ion battery, the obtained ZnCo2O4 microspheres deliver a reversible capacity of 965 mAh.g(-1) at 0.5 A .g(-1) after 200 cycles, and the capacity of the ZnCo2O4 microspheres still remains 882 mAh.g(-1) at 0.8 A .g(-1) over 350 cycles. The rate capability shows that a reversible capacity of 736 mAh.g(-1) is maintained at high current density of 2.0 A.g(-1).
