"textContent": "The present application discloses a composite graphite material, a method for preparing the same, a negative electrode sheet, a secondary battery, a battery module, a battery pack, and an electrical apparatus. The composite graphite material comprises a bulk particle and a cladding layer located on at least a partial surface of the bulk particle, the bulk particle is a secondary particle formed by aggregation of more than two primary particles, the bulk particle comprises artificial graphite, the cladding layer comprises amorphous carbon, and an air oxidation temperature T of the composite graphite material is from 630°C to 730°C. The composite graphite material in the present application can enable the secondary battery to not only have a high energy density, but also have significantly improved fast charging performance and low-temperature power performance.",
