摘要：The graphene/mesocarbon microbead(MCMB)composite is assessed as an anode material with a high capacity for lithium-ion *** composite electrode exhibits improved cycling stability and rate capability,delivering a high initial charge/discharge capacity of 421.4 mA·h/g/494.8 mA·h/g as well as an excellent capacity retention over 500 cycles at a current density of 40 mA/*** a higher current density of 800 mA/g,the electrode still retains 35%of its initial capacity which exceeds the capacity retention of pure graphene or MCMB reference *** voltammetry and electrochemical impedance spectroscopy reveal that the composite electrode favors electrochemical kinetics as compared with graphene and MCMB *** electrochemical properties suggest a strong synergetic effect between highly conductive graphene and MCMB.
