Patent ID: 8580437

Claim:
A method for forming a negative electrode for a lithium secondary battery, comprising: providing a paste comprising graphite particulates having an aspect ratio of 1.2 to 5, wherein the graphite particulates comprise 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, an organic 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, wherein the content of the organic binder is 3 to 20% by weight based on the mixture of the graphite particles and the organic binder; and pressing the mixture and the current collector to provide a density of the mixture of graphite particulates and organic binder of 1.5 to 1.9 g/cm 3 .
