MULTI-LAYER STRUCTURED CARBONACEOUS MATERIAL, PROCESS FOR PRODUCING THE SAME, AND NONAQUEOUS SECONDARY BATTERY ADOPTING THE SAME

Disclosed is a multi-layer structured carbonaceous material obtained by mixing graphitic carbon particles with an organic compound and by thermally treating the mixture, wherein loop structures are present at an edge portion of each of the graphitic carbon particles, and wherein the graphitic carbon particles have carbonized products of the organic compound affixed to surfaces of the particles, respectively, while maintaining the loop structures.
