This will be neat if it works but really there isn't going to be a huge market for 500+ mile cars vs the cost savings of getting a 300-400 mile car. The exception might be road-trippers and people who do a lot of towing but I suspect that is a much smaller population than people tend to think.

If it could only reduce the weight of current EVs that would be a win. Most electric vehicles weight 1000 lbs or more than their ICE counterparts, and in the extreme case of the Hummer, the total weight is over 9000 lbs. Vehicles seem to be continuously ballooning in size, so whether that continues or eventual legislation forces more reasonable sizes, higher energy density would be very welcome.
When will this meme die? A Model 3 is very comparable in weight to an Audi S3. The Hyundai Ionic 5 is comparable weight and interior volume to a Toyota Rav 4. The Hummer is a monster either way and is not a good sample.

People like having extra capacity even if they scarcely use that capacity. This is why the F150 is the best selling car in America. Not to mention its better in general to have extra battery capacity than you might reasonably need today, as it will degrade with age, or temperature.
It's also why the F150 lightning appears to be an absolute flop: Its range goes to crap when you're towing, and people who want F150's at least think of themselves as people who want to be able to tow. (Actual towing with F150's is likely low, but most people who buy one, want to have the option.)
I've only found this to be true on the internet. In the real world, it is much less common.
Lots of people realize that their truck is just the commuter and home depot stuff hauler.
> it could release highly toxic hydrogen sulfide gas. How bad is it in real world conditions? Because from what I'm reading it's not the "it makes you sick" kind of toxic, but rather the "it kills you in seconds" kind of toxic.
UK figures for safe working concentration in air, from memory, hydrogen cyanide 11ppm, hydrogen sulphide 10ppm

Just people who go on road trips with 2 or more mountain bikes need this. This is not theoretical, a Model Y has its range ruined with 2 or more mountain bikes attached to the exterior. Like ~140 miles max on our trip with 4 mountain bikes. And then you tend to go to more remote areas so that makes it even worse. So yes, our family is eagerly awaiting a 500 mile range ev

I feel like that's quite a stretch of the word comparable. The Model 3 is 14% heavier than the Audi: https://www.edmunds.com/car-comparisons/?veh1=401999985&veh2... And the Ioniq5 is 35% heavier than the RAV4: https://www.edmunds.com/car-comparisons/?veh1=401958795&veh2...
From Google: Model 3: 3,862 to 4,048 lbs Audi S3: 3,527 lbs 9-14% seems comparable IMO and worst case roughly half he mentioned 1000 lbs.

And the Audi is already on the heavier side for vehicles of that size. Mainstream non-'luxury' sedans of comparable size are often 3200-3300, like Accord/Camry/Altima, and the construction of these vehicles is a more equal comparison.

The additional capacity might be wanted in cold climates. The massive range drop when running the cabin heater plus slow charging in cold environments definitely makes me pause when considering an EV.

Wikipedia says 13000 Wh/kg, but you have to keep in mind that due to physics, wear considerations, and emissions regulation, most cars are only 20-40% efficient. At a 20% efficiency, that's 2600 Wh/kg. This is further constrained by gear ratios, meaning not all power is available at all times.
Exactly. Gasoline is much, much more energy dense than Li-Ion batteries, but in terms of dollars per mile, an electric car is 2x-4x cheaper to drive than an ICE car. That's because an internal combustion engine wastes the majority of gasoline's energy as heat, while electric motors use most of the battery's energy to move the car.
I guess that depends on your perspective and/or where you live.
I rented a Tesla in December once and was freezing the whole drive. A gasoline engine generates extra heat you can use to heat the cabin, whereas an electric car needs extra heaters (which IME weren’t working that well in that old Model S)
