1. A lithium secondary battery, comprising:
- a vessel;
a positive electrode containing an active material housed in the vessel;
a lithium ion conductive electrolyte in the vessel; and
a negative electrode arranged in the vessel containing carbonaceous material spherical particles as active materials that absorb and discharge lithium ions, the carbonaceous material spherical particles containing a graphitoid layered structure part and a turbulence-layered structure part, fine structures of the carbonaceous material spherical particle being arranged in point-orientation.

Abstract
A lithium secondary battery which comprises a vessel, a positive electrode, a negative electrode and an electrolyte. Both of the electrodes are placed in the vessel and the vessel is filled with the electrolyte. The negative electrode includes carbonaceous material spherical particles or carbonaceous fibers which absorb and discharge lithium ions. The carbonaceous material has a graphite-like layered structure part and a turbulence-layered structure part. Fine structures of the carbonaceous material spherical particles are arranged in point-orientation.
