Abstract

The invention relates to the field of carbon materials, in particular to an amorphous carbon material and a preparing method and application. The amorphous carbon material is characterized in that thereal density rho of the amorphous carbon material and the interlayer spacing d002 obtained through powder XRD spectral analysis meet the relation: 100*rho*d002> / =70; the interlayer spacing d002, La and Lc meet the relation: Lc*d002 < / =0.58 and 100*(Lc / La2)*d0023< / =0.425; on the basis of the total mass of the amorphous carbon material, the amorphous carbon material contains 0.001-2% of silicon component and 0.001-2% of aluminum component. The prepared amorphous carbon material has good heat conductivity and can provide high battery capacity.

Description

technical field

[0001] The invention relates to the field of carbon materials, in particular to an amorphous carbon material and its preparation method and application. Background technique

[0002] In the field of secondary batteries, especially in the field of lithium-ion secondary batteries, graphite materials have become the main materials due to their high electronic conductivity, small volume change before and after layered structure, high lithium-intercalation capacity and low lithium-intercalation potential. Commercial Li-ion battery anode materials. The secondary battery can be used repeatedly, and it can be used again when the battery is fully discharged.

[0003] With the development of secondary battery technology, the requirements for negative electrode materials continue to increase, and amorphous carbon materials have gradually attracted attention. Amorphous carbon materials have the advantages of large layer spacing, good compatibility with electrolyte, fas...
