In the first experiment, we can get the best battery performance composition is Zn : Al=77.7:22.3(wt.%) in different ratio between Zn and Al. There is another experiment for Zn-Al alloy use digestion method to promote the surface area of Zinc plate. We can use this method to promote performance, as Zinc is more than 77.7 wt. % , but as Zinc is less then 77.7 wt. %, performance will be worse. We design three Zn- Mg alloys melt in vacuum environment in second experiment. It’s because Mg will precipitate first, and we don’t get pure intermetallic compound we design. For the research in battery performance, all three Zn-Mg alloys are not good but in the corrosion resistance, they have special performanc
