> Worse, batteries are still very, very heavy compared to the energy they store Lithium-Sulfur batteries will help here. They have a higher gravimetric energy density than other battery chemistries. The main problem with Li-S batteries is the poor cycle life but progress is being made in improving that: https://www.monash.edu/news/articles/supercharging-tomorrow-australia-first-to-test-new-lithium-batteries https://www.monash.edu/news/articles/supercharging-tomorrow-...
