Water-soluble polymer binders are employed in the preparation of electrode to
enhance the performance of supercapacitor. In this research, three different polymer
binders were used as an alternative to the current synthetic binders in the preparation
of electrical double-layer capacitor (EDLC). Carboxymethyl cellulose-ammonium
nitrate-ethylene glycol was utilized as solid polymer electrolyte (SPE). The effects of
different polymer binder were investigated in terms of their electrode structure and
electrochemical performance of EDLC cell. The result of conductivity and capacitance
water-soluble polymer binder become similar performance with synthetic binder used
in EDLC. The surface morphology compared to synthetic binder also shows good
quality of electrode. This research benefits us to preserve our environment by using
organic binder and maintain a low cost electrode. For further research, other organic
and low cost material also can be analyze to replace synthetic binder and provide us
a better performance of EDLC in future.
