Project Update Salt Water Battery

Goal- Our goal is to create a functioning salt water battery because normal batteries are not very convenient for developing countries. They are either too expensive or difficult to construct but are still needed for things like flashlights, transportation or even water filters.



  • We used a counterpunch on the copper and zinc to make it easier to drill holes into them. In total there were 36 of each metal. This was done to make the metal connected and easier to keep in place while in the battery.

  • In order to drill into the copper and zinc we also used a wood backing that made the drilling smoother


  • To connect them we used a screw and 3 nuts to connect one piece of zinc to one piece of copper






  • There is one piece of copper and one piece of zinc in each cell

  • Top part with screw will be above the water
