Title: METHOD FOR PREPARING ELECTRODE MATERIAL, ELECTRODE MATERIAL AND BATTERY
Abstract:
Disclosed are a method for preparing an electrode material, an electrode material and a battery, these being used for solving the problem in the prior art of a silicon negative electrode material in a battery easily becoming a powder when in a fully intercalated state. The electrode material comprises: a layered silicon core and graphene quantum dots, wherein the layered silicon core comprises at least two layers of silicon-based material, there is an interspace between two adjacent layers among the at least two layers of silicon-based material, and the silicon-based material comprises at least one of silicon or silicon oxides; and the graphene quantum dots are located in the interspace between the at least two layers of silicon-based material.
