No, that doesn't seem likely to me at all. Lithium prices are high because the industry is not very well developed and the demand is skyrocketing. Borax is co-located with lithium deposits (in some places) and is extracted by a similar process at similar scales and it costs 100x less than lithium. And for some reason nobody looks at the gigantic land scar at a borax mine and starts screaming about the environmental cost, because there's no oil billionaire astroturf fund dedicated to whining about boron.
