Abstract: Carbon films were made using spray_thermal evaporation from a kind of pyrolytic carbon powder. The films obtained with graphite structure were both potentio_statically and galvanostaically tested. Cycling patterns indicated a reduction peak on the first cycle corresponding to the formation of solid electrolyte interface, and the capacity values and x values were quite acceptable compared to theoretical ones when charging_discharging current density was suitable. Based on the experimental results, the obtained carbon films could be used as anode materials for relatively determining the electrochemical performances of cathode materials.
