摘要： Provided are a graphene powder, a production method thereof, and an electrochemical device comprising the same. The graphene powder has an elemental ratio of oxygen atoms to carbon atoms of not less than 0.07 and not more than 0.13 and an elemental ratio of nitrogen atoms to carbon atoms of not more than 0.01. In the production method, the graphene powder is produced by using a dithionous acid salt as a reducing agent. Since the graphene has a low content of nitrogen atoms and a proper amount of oxygen atoms and a proper defect, the graphene is provided with good performance of both dispersibility and conductive property, and is usable as a good conductive additive, such as the one for a lithium ion battery electrode. The production method has the advantages of low cost, high efficiency and low toxicity.
