batteries are terrible for the environment to make and recycle.That's what I mean about batteries being unsolvable. They're not environmentally friendly to produce, charging takes a long time, and range leads more to be desired. But are all these problems fundamentally unsolvable due to laws of physics or are they just difficult problems with our current technologies?
lithium is a very limited resource on earth,. there really isn't enough for it to be the backbone of our energy needs.
hydrogen is more energy dense. to get a car to go a mere 300 miles on EV batteries it currently takes hundreds of pounds of battery. a compressed hydrogen car will exceed 1000. a liquid hydrogen car would be 10,000.
EV is slow to charge hence why no is talking about battery as a service. to go long distance you need to swap batteries. compressed hydrogen could be refueled like a gas car.
Just because the tech doesn't exist today, doesn't mean there can't exist "miracle batteries" in 20/50/100 years that have 3 or 30 times the energy capacity and able to charge in 30 seconds.
Those are current battery problems, and a good reason why hydrogen is currently better. But this seemingly assumes that electric hits a wall while hydrogen improves from some standpoint. In other words what in the future makes hydrogen more viable than it is right now/makes electric less viable than it is right now?
I find it problematic because batteries as a concept are way more open ended. They don't have to be lithium ion, for example.
