A lithium secondary battery composite electrode material and a lithium secondary battery, wherein the lithium secondary battery composite electrode material comprises at least: an electrode living material powder and a nano coating layer coated on a surface of the electrode living material powder. Wherein the nano-coating layer is formed by a metastable polymer, Compound A, Compound B or a combination thereof, the compound A is a polymer monomer having a reactive terminal functional group, and the compound B is a heterocyclic amine group. The initiator of the aromatic derivative, and the weight ratio of the nano-coating layer to the lithium secondary battery composite electrode material is 0.005% to 10%. |
