We have faster charging speeds with lithium today, 800v cars that can charge at 300KW+ have been on the market for half a decade, BYD has launched cars that can charge at 2-3x that speed. The charging infrastructure is the bottleneck there, even if all new cars could charge at those speeds it wouldn't mean much because hardly any chargers can support it.

Besides it's almost moot, most EV owners aren't charging via fast chargers like you would fill up an ICE car, they're charging at home at much cheaper rates and only using fast chargers for particularly long trips.

Same compromise I made when I bought the base range version of my car with LFP chemistry. But I would not go lower in range than that. LFP is already much safer than any gasoline engine. I would like sodium just for the reliable range on low temperatures. Probably in the next years we will reach comparable density for sodium.

The issue with that is that your range at least needs to make it between charging stations on the highway to be a realistic choice for many people. That might not be a problem in major corridors, but in sparser areas like the US midwest, it's a legitimate concern.

Doesn't mean Na+ is bad, it's just a young technology. In the next few years I expect to see the energy density increasing rapidly.

I looked it up. 2022 IIHS crash tests showed the Tesla model 3 as being much safer in front impacts.

Modern cars may make the engine fall in a crash, but it’s still better not to have that mass there in the first place. Having said that, the safety advantages of a frunk may be reduced if you have a bunch of heavy cargo in there.
