NEGATIVE ELECTRODE MATERIAL, NEGATIVE ELECTRODE PLATE, ELECTROCHEMICAL APPARATUS, AND ELECTRIC DEVICE

A negative electrode material includes a core and a shell layer. The core is porous carbon with pores; where a silicon material is present on wall surfaces of the pores. The shell layer is a carbon material, and the shell layer encapsulates the core surface, sealing the pores. In the negative electrode material, the porous carbon and the carbon material of the shell layer have a disordered structure, resulting in less lithium storage. The pores serve as the primary region for lithium storage, with the silicon material present on the wall surfaces of the pores.
