This project focuses on substituting the binder in anode with natural material with the
intention on introducing a cost effective and greener electrode fabrication.
Commercially, most of the binder in battery production is PVDF which is a nonhazardous
polymer, but N-methyl-2-pyrrolidon (NMP) is needed as solvent. It is a
hazardous organic solvent. In addition, the price of PVDF and NMP is very expensive.
Methylcellulose (MC) is chosen as natural binder to substitutes PVDF. Unlike PVDF, MC
soluble in water, this can further reduce the overall cost of making electrodes. In this
project, two anode were prepared which includes PVDF as control and MC in anode,
zinc and zinc sulfate used as active material while distill water and NMP as solvent.
The OCV of single cell proton battery with binder MC is 0.36V. SEM showed the
formation of composition and porosity for MC anode is smoother and better compared
to PVDF anode.
