Abstract

In this study, the properties of MCMB anode Mixed with KCF were evaluated, KCF material was used as not only conducting agent but also active material, The Electirc conductivity of MCMB and KCF were 23.7S/cm and 45.8S/cm. Characteristics of anode with different KCF contents were the best effect at 2wt%. The 1st Ah efficiency of cells were increased with increment of KCF contents. The internal resistance and the rate capability were $1.59{\Omega}$ and 135mAh/g at 2C, The discharge capacity was gradually faded with the charge-discharge cycling to about 50th cycles.
