The energy density of lithium-ion batteries is significantly lower than that of gasoline when comparing on a weight basis.
- Lithium-ion battery energy density: Current commercial lithium-ion batteries typically have an energy density in the range of 200-300 Wh/kg. Advanced and experimental cells have reached about 700 Wh/kg, with projections that they may reach up to 1,250 Wh/kg by the 2040s.
- Gasoline energy density: Gasoline has an extremely high energy density of approximately 12,000 Wh/kg, which is roughly 40 to 60 times higher than today’s lithium-ion batteries.
This vast gap in energy density means that, by weight, gasoline stores far more energy than lithium-ion batteries. Even with technological improvements potentially tripling the energy density of lithium-ion batteries in future decades, they would still lag significantly behind gasoline’s energy content per kilogram.
In summary, lithium-ion batteries offer energy densities around 200-300 Wh/kg today, with experimental advances nearing 700 Wh/kg, whereas gasoline provides about 12,000 Wh/kg—making gasoline approximately 40 to 60 times more energy-dense by weight than current lithium-ion technology.
