There are three main components that made up an electrode which is active material,
conductive additive and binder. Researcher has been focusing their attention on the
studies of active material and conductive additives to improve the battery
performance. However, the binder itself is proven to play an important role in
improving the battery performance. In conventional electrode, Polyvinylidene
Difluoride (PVDF) is used as binder. However, the usage of PVDF is proven harmful to
the environment. The usage of PVDF require inorganic solvent such as N-Methyl
Pyrrolidone (NMP) which is volatile to the environment. In addition, the PVDF is
expensive. Thus, replacing the PVDF with an organic based and cheaper binder is
needed. In this research, carboxymethyl cellulose (CMC) is studied as binder in anode
electrode. The electrode is characterized by using X Ray Diffraction and Scanning
Electron Microscope. The characteristic of the battery fabricated is determined by
measuring the Open Circuit Voltage and charge-discharge characteristics.
