a wish list the mobile phone battery
- reversible
- environmentally friendly
- high rate of discharge
- fast charge
- long cycle life
- small watt hours per kg watt hours per cm3

energy chemical → heat/light
2CH3OH + 3O2 → 2CO2 + 4H2O

corrosion splitting a reaction in two
Zn + 2HCl → ZnCl2 + H2
Zn Zn2+ + 2e 2H+ + 2e H2
Zn + 2H+ → Zn2+ + H2

energy chemical → electrical
Zn + 2H+ → Zn2+ + H2
Zn Zn2+ + 2e 2H+ + 2e H2

stability the one with the copper top
anode:Zn → Zn2+ + 2e
cathode:2MnO2 to Mn2O3
Zn + 2MnO2 + H2O → Zn(OH)2 + Mn2O3
Zn + 2OH- → Zn(OH)2 + 2e
