Amorphous carbon material, preparation method and use thereof

Abstract

The present disclosure relates to the field of carbon materials, in particular to an amorphous carbon material and a preparation method and an application thereof. The amorphous carbon material has the following characteristics: (1) a true density ρ of the amorphous carbon material and a interlayer spacing d002 obtained by powder X-Ray Diffraction (XRD) spectrum analysis satisfy the following relational formula: 100×ρ×d002≥70; (2) the interlayer spacing d002, La and Lc of the amorphous carbon material obtained by powder XRD spectrum analysis satisfy the following relational formula: Lc×d002≤0.58, and 100×(Lc/La2)×d0023≤0.425, wherein ρ is denoted by the unit of g/cm3, each of d002, Lc and La is denoted by the unit of nm. The amorphous carbon material prepared by the present disclosure has desirable heat transfer performance and can provide high battery capacity.
