So, how to process zinc powder into usable and high-performance zinc anode is of great significance to design a practical zinc anode. In this paper, we develop a simple and effective route to process zinc powder into usable and high-performance zinc anode by applying multifunctional pristine graphene (PG) network.
Electrochemical system The prepared zinc powder could easily be removed from the cathode surface and was washed in distilled water for several times until all the possible existing alkaline solution was removed from the powder particles. This was verified by adding a few droplets of phenolphthalein to the ablution water.
Due to the higher specific surface area and the dendrite nanostructure of the prepared zinc powder, it could be used as an anode material in zinc-MnO2 and zinc-silver oxide batteries which required a larger specific surface area , also it may be suitable for preparation of zinc rich-paints with improved properties.
The presence of zinc oxide in the powder results from a trace of an alkaline zinc oxide solution which may be entrapped within the powder in addition to a further oxidation during the drying. However, this zinc oxide is below the recommended value, as the percentage of zinc powder obtained is 99.3%.
A practicable zinc powder-based anode was developed for aqueous zinc ion batteries. Pristine graphene (PG) can obviously enhance the processing and battery performance of commercial zinc powder. The ZIB devices with enhanced energy density were fabricated based on the Zn powder/PG anode.
