Contributing to the Sustainable Development of New Energy Materials: Current Research Status and Future Fate of Conductive Agents for Lithium Iron Phosphate Batteries

Abstract In the face of the global resource and energy crisis, new energy has become one of the research priorities, and lithium iron phosphate (LFP) batteries are giving rise to a new generation of high‐power lithium‐ion batteries. Carbon‐based materials, as important basic materials, are widely used in various fields with their excellent physicochemical properties, which greatly support the research of dual‐carbon policy. Traditional conductive agents, however, have gradually shown limitations in certain applications of high‐performance lithium‐ion batteries. The development and application of new highly conductive carbon‐based conductive agents has become a mainstream trend in the research of anode conductive agents for lithium‐ion batteries. At present, the conventional conductive agent cannot meet the development needs of high‐performance lithium‐ion batteries. The research and application of new high‐conductivity carbon‐based conductive agents has become the main stream of research and trends in conductive agents for the cathode of lithium‐ion batteries. In this paper, carbon black (CB), carbon nanotubes (CNTs) and graphene are taken as typical materials for carbon‐based conductive agents for LFP batteries as examples, which are individually combined as LFP cathode conductive agents and carbon doped composites, and the synthesis method and action mechanism are discussed. The future research focus on lithium‐ion batteries and new carbon‐based cathode conductors is discussed, providing a reference for the further development of cathode conductors.
