Abstract

The present disclosure relates to the field of carbon materials, in particular to an amorphous carbon material and a preparation method and an use thereof. The amorphous carbon material has the following characteristics: (1) the true density ρ of the amorphous carbon material and the interlayer spacing d002 obtained by powder XRD spectrum analysis satisfy the relational formula: 100×ρ×d002≥70; (2) the interlayer spacing d002, La and Lc satisfy the following relational formula: Lcλd002≤0.58; and 100×(Lc/La2)×d0023≤0.425; (3) the amorphous carbon material contains 0.001-2% of a silicon component and 0.001-2% of an aluminum component, based on the total mass of the amorphous carbon material. The amorphous carbon material prepared by the present disclosure has desirable heat transfer performance and can provide high battery capacity.
