Embodiment Construction
[0023] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.
[0024] The invention provides a preparation method of a lithium-carbon composite material, comprising the following steps:
[0025] S1. Preparation of a micron lithium powder mixed solution: metal lithium is dispersed by liquid phase buoyancy in an organic solvent to obtain a micron lithium powder mixed solution.
[0026] S2, adjusting the solid content of the lithium powder: the micron lithium powder mixed solution in step S1 is left still, and a part of the organic solvent in the micron lithium powder mixed solution is discharged, so that the solid content of the lithium powder in the mixed solution is adjusted. to 25% to 35%.
[0027] S3. Pre...
