Figure 6. Electrochemical characterizations of S90-2.5% r-GO(S) & S90-2.5% r-GO(NS) composites.
(a) Cyclic voltammetry of S90-2.5% r-GO(S) at a scan rate of 20 μV/s and within the potential range 1.2–3.0 V. (b) Cycling performance comparison between both the S90-2.5% r-GO composites at 200 mA g−1 rate. (c) Cycling performance comparison between both the S90-2.5% r-GO composites at 1000 mA g−1 rate. (d) Rate performance comparison between both S90-2.5% r-GO composites and bulk S90 copolymer at different current rates. (e) Long term cycling performance of S90-2.5% r-GO(S) composite at 2000 mA g−1 current rate.
