▎ 摘  要

NOVELTY - The composite (10) comprises active material particles (12) of a titanium composite oxide or an oxide of titanium, and a graphene structure (11) including a carbon material having a graphene framework defining a graphene surface. The graphene structure is located in between the active material particles and has at least one side surface (11a) in contact with the active material particles. The side surface includes the carbon material whose graphene surface is slanted relative to the side surface. USE - Composite for active material (claimed) of negative electrode of non-aqueous electrolyte battery (claimed). Uses include but are not limited to a lithium-ion secondary battery used as a power source for vehicles such as hybrid vehicles or electric cars, or as uninterruptible power supply for mobile phone base stations. ADVANTAGE - The composite exhibits excellent repetition stability, and allows the non-aqueous electrolyte battery using this composite to be operated even at a high current. A conductive agent enhances the current collection performance of the active material, and suppresses the contact resistance between the active material and the current collector. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method of manufacturing the composite. DESCRIPTION OF DRAWING(S) - The drawing is a schematic cross-sectional view showing a composite.
