The present application relates to the field of secondary batteries and, particularly, relates to a negative electrode material for the secondary battery, a method for preparing the same, and a secondary battery containing the same. The negative electrode material includes a kernel particle, a connection carbon layer, a conductive carbon microparticle, the connection carbon layer is coated on a surface of the kernel particle, and the conductive carbon microparticle is distributed on a surface of the connection carbon layer. A high-molecular polymer is used as binder. A layer of conductive carbon microparticle is uniformly coated on a surface of the negative electrode active material, so that a stable and effective conductive network is formed in the electrode plate, thereby significantly improving a dynamic performance of the negative electrode material and providing a battery containing the negative electrode material with high rate performance and fast charging capability.
