Abstract
Provided are a natural graphite, a modified natural graphite material prepared therefrom, a preparation method, and applications. The natural graphite has the following characteristics: a particle size D50 smaller than 10 μm, and D90/D10<2.5; a 002 interplanar spacing ranging from 0.336 to 0.360 nm, I/I≤35; a saturated tap density greater than or equal to 0.6 g/cc and smaller than 1.3 g/cc; and a specific surface area greater than or equal to 1.0 m/g and smaller than 10.0 m/g. The provided natural graphite has specific particle size, orientation, tap density and surface area and can serve as a raw material for preparing modified natural graphite material, and the prepared modified natural graphite material has high isotropy and thus has better rate performance and cycle performance.
