And gasoline fires and high speed collisions aren't? This is the bit of paranoia around EV deployment that I genuinely fail to understand. Personal vehicles are by far the most dangerous apparatus with which we interact, already. And we're fine with it! Have you ever, even once , called a Civic or Vespa "scary"? But put a battery in it suddenly they need new tech before you'll be comfortable?

It's not just vehicles. Battery fires from electric bikes and scooters have also caused issues. And currently you can't put a battery pack into plane hold luggage because of fire risks.

There is no reason I can’t put a swimming pool size battery under my house. I don’t care what the energy density is, make it bulletproof and cheap and massive.

Cost is a reason. You need to dig out that dirt (which is expensive), it needs supports, your house needs support around it/through it… Making things bulletproof and massive runs opposite of cheap

It is time to standardize EV batteries like wheels: 5-10 mainstream types & competition on quality vs. price vs. range. Regulator help is needed here.

note sodium-ion is no longer two or three times the weight of lithium-ion, there is only a +33% penalty apparently the problem is there is not yet enough volume in production to compete on price, which I thought was the whole point? > sodium-ion specs have improved to the point that the technology could break into the general EV market. A recent study by Moritz Schütte at Aachen University in Germany and his colleagu…
