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 16

Rate capability (between 0.01 V and 3 V) for the cobalt oxide (power = 100 W and time = 60 min for sputtering cobalt on nickel foam) and cobalt oxide/carbon nanotubes/graphene composites (power = 100 W and time = 60 min for sputtering cobalt on carbon nanotubes/graphene composites).
