Abstract
The aim of this project is to study the effect of chitosan binder in graphene anode
on electrochemical and physical performance of the electrode. Graphene and chitosan
binder were used to prepare graphene anode where graphene was fixed to 0.02 g with
different percentage of chitosan binder. The working electrode allowed to be
characterized as a half-cell setting for the characterization. The structural analysis
confirmed the formation of graphene's layered structure. The binder also successfully
bind the active material matrix, graphene together based on the analysis of morphology.
With the optimum scanning rate (0.1 mV s-1) in cyclic voltammetry (CV), the best
performance is the 10% chitosan electrode. The anode's capacity is slowly fading after
cycling. The anode will degrade during the initial cycles throughout the
characterization. Combination of graphene and chitosan binder showed promising
results in this study.
