| Abstract: | The advantages and disadvantages of mesocarbon microbeads （ MCMB ） used as anode material for power lithium - ion battery, as well as the necessity of modification were discussed. The principle of modification methods such as surface oxidation, thermal expansion, coating and doping modification were briefly introduced. The capacity, cyclic performance or discharge performance of MCMB anode were improved significantly through modifications. The enhancing of electrode performance was analyzed. |
