[Ouyang Minggao, Academician of the Chinese Academy of Sciences: the reasonable price range of lithium carbonate is 100000-200000 yuan]. Ouyang Minggao, academician of the Chinese Academy of Sciences, said that to set a reasonable range for the price of lithium carbonate, on the one hand, the production cost should be calculated. at the same time, we should also consider the issue of battery recycling and the safety of the industrial chain. As far as the cost of lithium carbonate is concerned, from the lower cost of salt lake to the higher cost of mica, the current production cost is in the range of 50, 000-160000 yuan per ton. From the perspective of battery recycling, if the price of lithium carbonate is less than 100000 yuan per ton, the battery recycling industry will be greatly affected.
