NOVELTY - An anode comprises 40-44 wt.% ternary lithium-iron phosphate, 46-50 wt.% N-methyl-2-pyrrolidone solvent and an additive comprising 2-3 wt.% polyvinylidene fluoride, 1-2 wt.% SP, 1-2 wt.% KS-6 graphite and 5-8 wt.% multilayer graphene. The multilayered graphene includes several layers of flaky graphene and diamond. The weight ratio of multilayered graphene and diamond is (4-6):1. The multilayered graphene comprises 6-8 layers of graphene. The thickness of each layer of the multilayered graphene is 0.3-1.0 nm. The diamond is spherical carbon having particle diameter of 0.7-1.6 nm. USE - Anode is used in lithium battery. ADVANTAGE - The multilayer graphene in the anode increases thermal conductivity and electroconductivity of the lithium battery, and effectively reduces internal resistance of the battery. When the battery is exposed to the high-temperature environment, the heat can be transmitted to the battery shell to dissipate outwardly, such that internal temperature of the battery is decreased and stability of the battery is maintained. The lithium battery provided with the anode is safe, and can adapt to the high temperature of 75 degrees C, and long service life. DETAILED DESCRIPTION - An anode comprises 40-44 wt.% ternary lithium-iron phosphate as main ingredient, 46-50 wt.% N-methyl-2-pyrrolidone solvent and an additive comprising 2-3 wt.% polyvinylidene fluoride, 1-2 wt.% SP, 1-2 wt.% KS-6 graphite and 5-8 wt.% multilayer graphene. The multilayered graphene includes several layers of flaky graphene and diamond located between two adjacent layers of the multilayered flaky graphene. The weight ratio of multilayered graphene and diamond is (4-6):1. The multilayered graphene comprises 6-8 layers of graphene. The thickness of each layer of the multilayered graphene is 0.3-1.0 nm. The spacing between the two adjacent layers of the multilayered graphene is 0.1-0.5 nm. The diamond is spherical carbon having particle diameter of 0.7-1.6 nm.
