    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.
