Energizer Work ExperienceNavy Project -Zinc-Air Prismatic Battery Carbon black and zinc anode + Nickel plated screen = stress test Hydrophobic Teflon = peel testExternal cans – welded conductive metal for testing long term voltage (performance testing)

Laboratory ManagementEnsured that my assigned was OSHA 5S approvedChemical inventory posted (must have only those chemicals in the lab and its corresponding MSDS)Hazardous materials Ensured proper handling and disposal Ergonomically friendly
