Abstract:Why do dead batteries bounce considerably higher than fresh batteries? This phenomenon has a chemical explanation that can be used to teach students about the chemistry of alkaline Zn/MnO2 cells. Batteries discharged to various extents can be tested for bounciness and conversion of Zn to ZnO. These measurements allow students to connect the chemistry that powers these batteries with the increased bouncing effect. The experiments can be presented as a teacher-led demonstration or hands-on laboratory for students.
