Samsung delivers 600-mile solid-state EV battery as it teases 9-minute charging and 20-year lifespan tech

There are probably more asterisks than starts inn that statement.

Is 20 years the average? The maximum under ideal circumstances? What would be the effective capacity of the battery at 19 years? What is the maintenance required?

Where would you drive in your phone, bro? Don't be silly.

Based on the article they are more expensive than li-ion batteries (for now), so probably not yet. And the article doesn't mention anything about this, but I imagine there would be scaling issues.

I don't think solid state batteries provide as much benefit in smaller devices.

Just a matter of faster charging, takes me maybe 5-10 minutes to fill up and pay, would take a lot longer for an EV. Certainly not an issue if every accommodation had charging points, as I'd then be unlikely to need a full charge during the day.

And yes, for regular day to day driving I would just charge at home, as I'm fortunate to have a garage. Not the case for many folks, sadly.

Definitely great news, and it's looking good that my next car will be an EV.

One car I had I could just about reach 600 miles if driving carefully on the highway. That was a diesel with a large tank. No other car I've had did better. My first car has a 300 mile range.

I might tap the center of that if I was doing near 100% highway, hypermiling and ran out the tank. But typically 300-500 in either of mine and I drive about 20 miles a day maximum.

Vehicles will always have specific use cases, it's just that most of North America's infrastructure is designed to accommodate vehicles with everything else being designed around that, put in as an afterthought or just not thought of in the first place (like cycling infrastructure). So people are using these machines for things that are outside their use case, as it has been for almost a century.

As things are right now, people would probably die if cars were outright banned. It's kind of funny how important personal vehicles have become and as such kind of scary how necessary they are (it's a bit of a paradox, isn't it?). To ban cars there first needs to be a good replacement option like well connected rail lines or cycling only roads (or at least protected bicycle lanes). These take time, money, resources and, most of all, political will to create. For most of the developed world money and resources aren't exactly an issue, the issue is politics that lock up those resources for vehicles.

I.e., funding for my cities major bicycle route that serves 1000+ people everyday is still only funded by my regions parks and recreation board which doesn't get enough money to maintain it properly. Even though it's really great, I can't use it after dark because there aren't any lights until I get to a shared route and there are a few bridges that are so uneven I have to walk across.

North America has to undo multiple decades of relentless car-centred development and the prevailing political climate means that will happen piecemeal at a municipal level, street by street, year by year. I personally don't want to wait for that though, so I'm learning Dutch.
