The research of graphene conductive agents in recent years is summarized from two aspects:better exerting the excellent e-lectronic conductivity of graphene and improving the steric effect on lithium ions.It is found that the current research has not formed a unified understanding on the performance of graphene conductive agent,and there are even contradictory conclusions in different stud-ies.Through further exploration of previous research,it is found that the research of graphene conductive agent is often based on the gra-phene performance and the results of the half-cell test,and the performance is attributed to the effect of graphene conductive agent on the electronic conductivity or ionic conductivity of the electrode plate based on experience,lacking direct evidence and comprehensive consideration.The problems causing this phenomenon are summarized in this paper,and the methods that can be improved are proposed.It is expected to provide new ideas for the commercial development of graphene conductive agents.
