Electric CarsChevy Volt: Charge uses 8 kWh of electricity to drive 40 miles
Equivalent in miles per gallon:
Energy Density: Lead Acid Car BatteryPb + PbO2 + 2 H2SO4 2 PbSO4 + 2 H2O
n = 4, Eo = 2.05 V, F = 96.5 kJ/V
G = -nFEo
Energy per kg:combined molar mass = 643 g/mol
Nickel Metal Hydride Batteries
Anode:
Cathode:
Alloy is a mixture of 1 part (lanthanum, cerium, neodymium) and 5 parts (nickel, cobalt, manganese, aluminum)
