Although lithium is very abundant in sea water, only lithium mineral extraction seems to be economically viable. The world's total reserves in lithium minerals is estimated at 13.5 Mt (not sure whether this refers to the weight of the mineral or its lithium content), according to Wikipedia. People often cite lithium scarcity as a reason why not everyone can have an electric vehicle.
Is that really true?
I can think of two circumstances under which the claim can be wrong:
- Lithium isn't so scarce, after all.
- Availability of Lithium isn't that crucial. (I.e., alternative, lithium-independent, energy storage designs exist)
I'm looking for reputable sources that support either of the above.
