1kg of lithium produces about 10kWh of storage for 15-20 years. 3-12 hours of storage is plenty for a >95% VRE grid.

1kg of uranium produces about 750W for 6 years.

There are about 20 million tonnes of conventional lithium economically accessible reserves (and it has only been of economic interest for a short time).

There are about 10 million tonnes of reasonably assured accessible uranium (not reserves, stuff assumed to exist). It has had many boom/bust cycles of prospecting.

Lithium batteries are not even being proposed as the main grid storage method.

Cobalt is the difficult one, especially with the child workers mining it.
