Lithium battery negative electrode, preparation method thereof and battery

The invention provides a lithium battery negative electrode which is composed of a lithiophilic coating and a current collector, wherein the lithiophilic coating comprises a lithiophilic agent, a lithium layer binding agent, a conductive agent and a binding agent; the lithiophilic agent comprises a metal sulfide, a metal oxide, nano Ni4P5 and nano metal; and the lithium layer binding agent is montmorillonite powder. The surface of the current collector is coated with the lithiophilic coating containing the lithiophilic agent and the lithium layer binding agent to manufacture the lithium battery negative electrode, the technical problem that dead lithium is easily formed in the charging and discharging process of the negative electrode is solved through the synergistic effect of the lithiophilic agent and the lithium layer binding agent, and by adopting the lithium battery negative electrode, the Coulombic efficiency and the reversible capacity of the battery can be effectively improved. The invention also pro
