Which current battery tech will we run into problems with, and which problems?

The amount of rare earth minerals needed for the current batteries and where they come from. The current Solid State batteries that are being worked on will need much less of those. This plays a big part in the high cost of the current tech.

the high weight it adds to the vehicle will also become a problem for the roads.

A high speed loading infrastructure will also become a problem because the net isnt really up to it in most countries. Atm the companies that own the power net is kinda waiting with the big investment into their networks hoping someone else will pay for it.

The recycling still is a problem, Tesla for example is just recommending old ones for other uses like storage, which they arent really perfect for.

Just saw an article stating that current batteries can be recycled completely to get the RE’s out and reused, that they don’t degrade

We could maybe use more recycling capability, no?

They can be, but nobody is really doing it. Cause it's cheaper to just buy the materials.

A lot of batteries are shipped of to be recycled, but aren't really recycled.

Some recycle a bit for pr purposes. The government's have to force them to do it, else it won't happen.

This is outdated information. There are multiple companies working on it right now. Redwood Materials is currently constructing a $3.5 billion dollar recycling facility near Reno that will produce enough materials for 1 million E.V. batteries by 2025 and 5 million by 2030. And that’s just one plant from one company. The company is also finalizing plans for an east coast facility as well.

Yeah working on it as in building factories to do it

Your comment was implying that no one was really bothering with it. That’s clearly not true.

All your information and reasoning is incorrect and outdated. RE is not actually rare. It’s just the name for that type of elements. Because of demand there is increasing amount of mining that will come online for those materials.

The batteries are not going to get thrown out. lots of recycling is already happening and a lot more will happen as more EV cars start aging out. For any recycling to be successful, the product that comes from recycling should have enough value to pay for the process of recycling and that is certainly true for EV batteries.

Maybe stop recycling your outdated talking points.

Have you heard about the liquid battery that someone just developed? I remember reading a story about it on Reddit about 3-6 months ago, the tech was basically a rechargeable liquid that you fill up your battery with, when the charge runs low it can be swapped out for freshly charged fluid at a filling station or recharged at home or work or wherever. I thought the whole concept and tech would be pretty revolutionary as it’s combining the low emissions of an EV with the convenience of gasoline style fill up. There was no word on how expensive the liquid battery fluid was to produce or how bad it is for the environment in terms of the inevitable spills that would happen. It was one of those things where I thought in 10 years it will be the norm and change the way we live or we’ll never hear anything about it ever again.

It's extremely low density. Not suitable for a car.

Similarly there was a battery swap battery that was an Aluminum metal battery. Amazing range. But required specialized facilities to recharge. So you would have to battery swap which is complicated and expensive.

The problem is that for most people, just plugging into their garage power outlet is the cheapest and most convenient system. (I'm not one of those people since I have no garage. But you design around the norm, not the exception.)
