Claim Text:
1. A graphite or combined graphite-carbon particulate for forming a lithium secondary battery anode material, said particulate consists of an orientation-controlling core particle of carbon or graphite and a plurality of satellite carbon or graphite particles that are each separately bonded or attached to said core particle at a surface of said core particle, wherein the core particle is spherical or ellipsoidal in shape with a major axis-to-minor axis ratio less than 2, or a fibril shape having a diameter from 200 nm to 5 μm, wherein said satellite particles are flat-shaped, disc-, platelet-, or flake-like particles having a thickness less than 100 nm and a lateral dimension less than 1 μm that are selected from nano graphene platelets, graphite oxide, or graphite fluoride each consisting of a graphite crystallite having a preferred orientation defined by a crystallographic c-axis, wherein said satellite particles are single-crystal structures that are randomly oriented with respect to one another for the purpose of increasing power capability of said particulate, and wherein said satellite particles are bonded to said core particle using a conductive binder selected from an amorphous carbon, a polymeric carbon, a pitch, petroleum pitch, coal tar pitch, meso-phase pitch, coke, a conductive organic or polymer, or a combination thereof.
