Most batteries do not use rare earth metals. Even if they did and it was an issue, we would find alternatives if that was necessary, just like rare earth free motors were developed to avoid all the downsides of that come with those.

Have a look at CATL’s sodium-ion batteries, they do not use anything expensive, rare, or particularly damaging to extract from the environment.

Uranium mines will become a problem if every country tries to make 25% of electricity with nuclear. Electrification of primary energy might even need more nuclear according to some pro nuclear people.

Many forget that while there is plenty of uranium on Earth, most of it occurs in very low concentrations. The lower the concentration, the higher the CO₂ emissions for the entire uranium chain from the mine to the fuel rod.

Meanwhile, renewable energies receive free fuel from the sun. They are already recyclable today and, with intelligent local and intercontinental grids, will also require fewer batteries for storage.
