Zusammenfassung:A negative electrode active material, a negative electrode and a battery are provided. The negative electrode active material includes an active particle and a modification layer. The active particle contains a silicon element, a carbon element, or a combination thereof. The modification layer covers on the surface of the active particle. The modification layer contains a reactive functional group of a coupling agent and a residual functional group of a metal compound. The reactive functional group of the coupling agent is bounded between the active particle and the residual functional group of the metal compound. The residual functional group of the metal compound contains a metal atom.
