Graphite particles and lithium secondary battery using the same as negative electrode
摘要:
A method for forming a negative electrode for a lithium secondary battery, includes providing a paste comprising graphite particulates comprise assembled or bound graphite particles in each of which a plurality of flat-shaped particles are assembled or bound together so that the planes of orientation are not parallel to one another, and the mixture including 3 to 10 parts by weight of the organic binder per 100 parts by weight of the graphite particulates, a binder and a solvent, coating the paste on a current collector, drying the paste coated on the current collector to form a mixture of the graphite particulates and the binder, and integrating the mixture with the current collector by pressing to provide a density of the mixture of graphite particulates and organic binder of 1.5 to 1.9 g/cm3.
