The invention relates to a method for preparing graphene through waste lithium batteries. The method is characterized in that graphite intercalation compounds in the waste lithium batteries are used as raw materials and stripped to obtain graphene. The method has the advantages that the raw materials are extensive, low in cost and suitable for industrial production, and recycling of resources in the waste lithium batteries is realized while the effective method for preparing graphene is found.
