Calculate the theoretical energy density, in Wh/kg, of a graphite/LiMn2O4 cell. If further including the electrolyte which is usually 20% of the cell mass, what would be the revised energy density? Solution energy density = Wh/kg = E Now mass = 0.2 m E =Wh/kg* 0.2 = 5 Wh/kg.

1. Calculate the theoretical energy density, in Wh/kg, of a graphite/LiMn2O4 cell. If further
including the electrolyte which is usually 20% of the cell mass, what would be the revised
energy density?
Solution
energy density = Wh/kg = E
Now mass = 0.2 m
E =Wh/kg* 0.2
= 5 Wh/kg
