The present disclosure relates to a novel process for preparing isotropic carbonaceous composite particles with favorable crystallographic, morphological & mechanical properties, wherein relatively fine carbonaceous primary particles are coated with a carbonaceous binder precursor material, agglomerated and finally heat-treated at temperatures between about 1850 and 3500 C. to convert the binder precursor material to non-graphitic or graphitic carbon, thereby resulting in stable highly isotropic carbonaceous composite materials wherein the primary particles of the aggregate are held together by the carbonized/graphitized binder. The present disclosure also relates to the isotropic carbonaceous composite particles obtainable by the process described herein. The disclosure further relates to uses of said isotropic carbonaceous composite material in various applications, including as active material in negative electrodes in lithium-ion batteries, and in secondary products containing said isotropic carbonaceous composite material.
