| titleOfInvention | Manufacturing method of carbon material for lithium secondary battery negative electrode |
| abstract | The present invention is a method of microencapsulating a heterogeneous carbon coating on the surface in order to suppress the exposure of the graphite tip crystal surface on the surface which causes deterioration such as low capacity of the existing graphite particles, initial efficiency reduction due to high side reactivity, and cycleability. The present invention relates to a method of manufacturing a carbon material for a lithium ion secondary battery negative electrode capable of high initial charge and discharge efficiency, suppression of deterioration in discharge capacity according to a cycle, and express high discharge capacity. The present invention utilizes the principle of changing the solubility of the solvent pitch to coat the coating film of the pitch on the surface of the graphite particles and heat-treat it in an inert or reducing atmosphere to form a lithium ion secondary of a dual structure having different surface and carbon structures. Battery carbon material can be manufactured industrially stably. |
