Abstract
The present disclosure relates to an anode material and a battery, the anode material comprises graphite, an interior and/or a surface of the graphite has pores, a pore volume of the anode material is V (cm3/kg), a specific surface area is S (m2/g), a tap density is T (g/cc), wherein, 2≤V*S/T≤10. By constructing the ratio relationship of the specific surface area, the pore volume and the tap density of the anode material, the overall distribution condition of defects such as pore pathways, crystal lattices and micro cracks in the graphite particles can be reflected, and within the limited range, the defect distribution in the anode material is uniform, and the uniformly distributed defect structure can reduce the expansion of the graphite anode material in the charging and discharging process, and improve electrical performance and processability.
