Abstract: Sub-micron size metallic particles were finely deposited on the surface of Carbonaceous Mesophase Spherules (CMS) by the decomposition and reduction of
organic metallic compound by solid-state reaction. Electrochemical cycling tests of coin cells show that the capacity retention at the 30th cycle is 90%, and special capacity is over 430 mAh g^-1, improving about 40\% versus pure
CMS electrode. Obtained Alloy/CMS composite powders with high special capacity are used as anode materials for lithium ion cells and can avoid the drastic volume
change when lithium inserting into and extracting from Alloy matrix, and improve the cycle performance of electrode.

Key words: organic metallic compound, alloy anode, carbonaceous mesophase spherules, lithium ion batteries
