To elaborate a little on ncmncm's reply, there is a cornucopia of alternatives available for grid battery storage. Sodium sulfur, iron air, aluminum air are three technologies we have waiting in the wings if lithium ever runs short. We'll never run out of any of those raw materials. (Edit: I'm not going to mention flow batteries, thermal storage (will we run out of rocks to heat up?), compressed air storage, or other chemicals like hydrogen or ammonia storage.) But, we are not short of lithium. There is plenty. There is a temporary shortage of lithium refining capacity, plants that take in the raw mined lithium and produce high purity lithium carbonate ready for the battery factories. But lithium mines? No shortage there. Also, it'd be reasonable to hold nuclear to the same "dust to dust" standard. Check out what it takes to produce and dispose of nuclear fuel and reaction vessels sometime.
