Abstract
A method for preparing an electrode material, an electrode material, and a battery are provided to resolve a prior-art problem that a silicon negative electrode material in a battery is prone to pulverization in a fully intercalated state. The electrode material includes a layered silicon core and graphene quantum dots. The layered silicon core includes at least two layers of silicon-based materials, an interlayer gap exists between two neighboring layers of the at least two layers of silicon-based materials, and the silicon-based material includes at least one of silicon or an oxide of silicon. The graphene quantum dots are located in the interlayer gap between the at least two layers of silicon-based materials.
