  • On paper, they look comparable to Tesla batteries. These new batteries are about half the size of Tesla’s, and the test was performed with a charging station that delivered more than twice the power of a typical Supercharger station. Try charging two of them at the speed our current charging infrastructure will support and it’ll take about 20 minutes.

    What seems to be new and improved is that these batteries can apparently accept more energy from a charging station without overheating, and the rate at which they permanently lose maximum capacity from Level 3 charging is reduced.

    I wonder how heavy they are compared to the competition?

















  • There’s no reason EVs have to be heavier forever

    That’s a bit of a stretch, unfortunately. The energy density of batteries is nowhere close to that of gasoline - joule for joule, gasoline weighs about 100 times less than batteries. Also, a fuel tank big enough to give its vehicle a 400 mile range will get lighter over the course of the trip, as the liquid fuel gets converted into polluting gas and exhausted into the atmosphere - batteries don’t get appreciably lighter as you discharge them.

    Agree that 400 miles range with charging stations as ubiquitous as today’s gas stations would help EV adoption. I do worry about the rollout of charging stations being slowed down by competition with expensive and fragile hydrogen tech (keep the hydrogen on boats and trains pls).
