How much fossil feul is used to mine those components?
The bigger question is how much water is needed. According to https://www.instituteforenergyresearch.org/renewable/the-environmental-impact-of-lithium-batteries, (sorry forgot how to post an active link - copy and paste), 500,000 gallons of water is required per metric ton (about 2205 pounds):
"The lithium extraction process uses a lot of water—approximately 500,000 gallons per metric ton of lithium. To extract lithium, miners drill a hole in salt flats and pump salty, mineral-rich brine to the surface. After several months the water evaporates, leaving a mixture of manganese, potassium, borax and lithium salts which is then filtered and placed into another evaporation pool. After between 12 and 18 months of this process, the mixture is filtered sufficiently that lithium carbonate can be extracted."
Then consider the land required for evaporation ponds for each half million gallons of water per ton of lithium. Tremendous waste of resources IMO.
