This project aims to introduce an affordable and more environmental friendly binder
material for proton battery configuration. PVDF was the mostly used binder in battery
production and it requires NMP as solvent which is expensive, volatile, flammable and
toxic. Besides, the price for PVDF and NMP were very expensive. Therefore, 2-
hydroxyethyl cellulose (2HEC) was introduced to replace PVDF as binder in battery
production. 2-HEC was water-soluble, affordable, allow electrode processing in
aqueous slurries and environmental friendly. In this project, two types of anode were
prepared that uses 2-HEC and PVDF as binder material respectively. Then the anodes
were compared in terms of structural and electrical performance. The OCV obtained
was 0.5V for single cell proton battery. SEM show 2-HEC anode has better formation
of electrode composition and porosity compared to PVDF anode.
