KAREN PEASE SAYS there is no shortage of lithium for electric-car batteries. “Older reserves figures don’t include, for example, the Kings Valley in Nevada, a mine that’s now expected to produce 25 billion pounds of lithium carbonate. That’s what many ‘peak lithium’ advocates claim the world’s entire reserves of lithium comprise because they don’t include the deposit at all, despite the fact that 173 boreholes to a depth of 40 meters over 80,000 acres determined an average lithium content of 0.279% and a commercial recovery factor of 85%. This is just one mine we’re talking about, and that’s enough lithium carbonate to produce the cells for almost 800 million 10kWh (Aptera-sized) battery packs.”
