Cost?
Charge time?
How often do they spontaneously combust?
Curious people want to know.
It won't matter. Tesla is supposed to start using their new aluminum ion batteries in some of their 2026 models. These new batteries hold almost 5 times the charge, weigh a fraction as much, fully charge in 10 minutes, have a service life of 40 years, and cost less than half of today's lithium ion batteries. And, the fire hazard is almost non-existent. Elon wants to market a car with these batteries in the 15k price range.
