We're going to get a 4x energy density improvement from lithium sulfur batteries, just as soon as production ramps up.
- bobthepanda 2y agoWikipedia lists the energy density of kerosene as 9.7k Wh/L, and lithium sulfur at 550 Wh/L, which is not great.
- zardo 2y agoHydrogen isn't so great either.
- koverstreet 2y agoBut burning kerosene is much less efficient, and turbine engines have a much lower power density than electric motors, so knock 2/3rds off the the kerosene number. 550 Wh/L would also be for the first lithium sulfur batteries to market, they'll double that down the road.
