A lithium-ion battery conductive bonding agent, including graphene and a first bonding agent grafted on a surface of the graphene, a production method for the conductive bonding agent, and an electrode plate and a lithium-ion battery that contain the conductive bonding agent, where the first bonding agent includes at least one of polyvinyl alcohol, sodium carboxymethyl cellulose, polyethylene glycol, polylactic acid, polymethyl methacrylate, polystyrene, polyvinylidene fluoride, a hexafluoropropylene polymer, styrene-butadiene rubber, sodium alginate, starch, cyclodextrin, or polysaccharide. The lithium-ion battery conductive bonding agent has good conductive performance and bonding performance and specific strength, improving mechanical strength of a whole electrode plate. The conductive bonding agent integrates a bonding agent and a conductive agent. This can improve content of active substance in the electrode plate, and further increase an energy density of an electrochemical cell. 1. A lithium-ion battery conductive bonding agent , comprising:graphene; anda first bonding agent grafted on a surface of the graphene, the first bonding agent comprising at least one of polyvinyl alcdhol, sodium carboxymethyl cellulose, polyethylene glycol, polylactic acid, polymethyl methacrylate, polystyrene, polyvinylidene fluoride, a hexafluoropropylene polymer, styrene-butadiene rubber, sodium alginate, starch, cyclodextrin, or polysaccharide.2. The lithium-ion battery conductive bonding agent of claim 1 , wherein the first bonding agent is at least one of the polyvinyl alcohol claim 1 , the sodium carboxymethyl cellulose claim 1 , the polyethylene glycol claim 1 , the sodium alginate claim 1 , the starch claim 1 , the cyclodextrin claim 1 , or the polysaccharide claim 1 , the lithium-ion battery conductive bonding agent further comprising a second bonding agent that is grafted on the surface of the graphene claim 1 , the second bonding agent being coupled to the first bonding ...
