Carbon micro-particles (CMPs) possessing smooth surface and sphere shape, which have wide size distribution from 0.5 to 5 ¦Ìm were prepared through a facile hydrothermal method using ¦Â-cyclodextrin as carbon source. Galvanostatic charge-discharge method was used to investigate the electrochemical performance of CMPs. The results showed that CMP anode exhibited an initial discharge capacity of 571 mAh g1 and a reversible capacity above 345 mAh g1 after 50 cycles. The good performance for the CMPs can be attributed to the smooth surface of the carbon spheres, which is advantageous in the formation of good and efficient passivation layers. This electrode material has promising applications in lithium ion batteries.
