  1. Other types of batteries Mercury cell Zn / HgO calculators, hearing aids Silver Oxide Zn / Ag2O watches, cameras Nickel Cadmium Cd / NiO rechargeable batteries Lithium cells Li / MnO2 pacemakers

  2. Car batteries Same as an electrochemical cell but reversible Pb + PbO2 + H2SO4  2PbSO4 + 2H2O Add electricity 2PbSO4 + 2H2O  Pb + PbO2 + H2SO4

  3. Aluminum versus steel AluminumSteel Hazardous waste from plants Hazardous waste from plants recycling is cheap recycling is cheap 15 times more energy to produce rusts and corrodes
