Is graphene mass-produced? Why do many products use graphene?

graphene is not mass-produced, and many products are fake with graphene. Although China ranks first in the original country of graphene technology at present, and the number of patents accepted is much ahead of other countries, there are indisputable facts that it is difficult to mass-produce graphene at low cost, the promotion cost is huge, and the upstream is strong and the downstream is weak. In the past, due to the immature technology, immature market, insufficient production line capacity and other factors, graphene was expensive, once as high as dozens of times the price of gold, which made it impossible to mass produce. Therefore, many products with graphene are fake.
