$5 of electricity is a LOT of electricity to get only 1kg of Lithium. That's like 50kWh or almost 2x the amount used per day in the average home. Are we currently using more energy than this to extract 1kg of Lithium?
Assuming this is the main cost, at $5,000/ton it's not so far from existing extraction methods:
> Most of the world’s lithium comes from brine deposits in South America, although companies like Talison also operate hard rock mines in Australia. The cost of extracting a ton from a brine site costs around $2,000 says Paes-Braga while mined ton of lithium costs closer to $4,000. (These are operational costs that do not include capital.)
Of course for those the main expense isn't electricity but labor, etc.
