LiCoO2 0.518 kW·h/kg
LiMn2O4 0.400 kW·h/kg
LiNiO2 0.630 kW·h/kg
LiFePO4 0.495 kW·h/kg
Li2FePO4F 0.414 kW·h/kg
LiCo1/3Ni1/3Mn1/3O2 0.576 kW·h/kg
Li(LiaNixMnyCoz)O2 0.920 kW·h/kg

Gasoline 13.1 kW.h/kg

Gasoline energy density is 150~300x that of Lithium batteries. There is simply no comparison. Before low-power microprocessors came along, serious effort were made into running laptops on propane or butane charge capsules.
