I just wonder if this guy could somehow support his statement by some solid facts. According to Fastmakers, the price of Lithium Carbonate 99% is 41000 yuan presumably per ton, which is bit more than $6kg (ie next to horrible) (https://www.fastmarkets.com/commodities/industrial-minerals/lithium-price-spotlight).

Lithium hydroxide price is according to London Metal Exchange $9/kg.
