- Silicon thick films were coated by fullerene thin film using plasma
assisted thermal evaporation technique at plasma power of 50 and
100 W. The fullerene coated silicon films were then used as anode
materials of lithium secondary batteries. The coated electrodes
demonstrated a lower initial irreversible capacity and a better
interfacial property, as shown by the cyclic voltammetry (CV)
measurements and impedance analysis. It was attributed to the
fullerene coating layer which could maintain the mechanical
stability of electrodes by suppressing the side reaction with the
electrolyte during the repeated charge-discharge tests.
