The invention discloses a coating agent, a modified graphite material, a preparation method and application of the modified graphite material, and a lithium ion battery. The coating agent comprises coumarone resin and wash oil, wherein a mass ratio of the coumarone resin to the wash oil is (1-3): 1. The coating agent and graphite are mixed according to a ratio of (7-15): 100 and carbonized to prepare the modified graphite material. The modified graphite material is uniform in coating and high in tap density. When the modified graphite material is used for preparing the lithium ion battery, the initial discharge efficiency of the prepared lithium ion battery is higher than or equal to 93.5%, the impedance of the lithium ion battery is significantly reduced, and the rate capability of the lithium ion battery is good.
