Original Abstract Submitted
A hard carbon material has a pore structure. A scattering vector of the pore structure in a small-angle X-ray scattering spectrum is N1 n, and 0.1≤N1≤7. The hard carbon material exhibits a scattering intensity convex peak. A full-width-at-half-maximum of the convex peak is L1 n, and 0.1≤L1≤3.5. A pore volume of micropores of the hard carbon material measured by a nitrogen adsorption method is V2 cc/g, and 0<V2≤0.01. The pore structure of the hard carbon material of this application includes micropores. During lithium storage, lithium ions can be stored in the micropores, thereby providing a reversible capacity. In addition, when used as a negative active material of an electrochemical device, the hard carbon material of this application endows the electrochemical device with a high energy density, a high first-cycle Coulombic efficiency, and good cycle performance.
