▎ 摘　　要

NOVELTY - A graphene composite conductive agent comprising a graphene conductive slurry, where the graphene is prepared in the following manner: the precursor, stabilizer, and dispersant are added into the reaction kettle for high-speed stirring, the dispersing rate is 500-2000 revolutions/minute, and the stirring time is 5-120 minutes. The obtained slurry is conveyed to a sand mill and ground at a controlled speed of 500-2000 revolutions/minute, grounding again under a homogenizer at a controlled pressure of 5-50 MPa. USE - The composite conductive agent graphene is useful in a lithium ion battery, which is useful as an auxiliary material lithium the ion battery, the main function is to construct a conductive network in the electrode material, improve the conductivity of the pole piece, and reduce the polarization of the system. ADVANTAGE - The graphene composite conductive agent: has high thermal conductivity, crystallinity, and electronic conductivity; can be combined with other conductive agents; and improves the conductivity of the anode of the lithium-ion battery, improves the content of the active material, capacity, and specific anode, and lithium the ion steric hindrance effect of the graphite alkene with large sheet diameter. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for : (1) an ion battery lithium.
