The Effects of Power Levels/Time Periods for Sputtering Cobalt onto Carbon Nanotubes/Graphene Composites and Cobalt Annealed on the Characteristics of Anode Materials for Lithium-Ion Batteries

Figure 15

The effects of cobalt oxide (power = 100 W and time = 60 min for sputtering cobalt on nickel foam), cobalt oxide/carbon nanotubes/graphene composites (power = 100 W and time = 60 min for sputtering cobalt on carbon nanotubes/graphene composites), and different charge/discharge cycles on the specific capacity (0.1 C).
