Abstract: The present invention relates to an intermediate for preparing porous silicon oxycarbide, a method of preparing the same, and a lithium secondary battery including porous silicon oxycarbide prepared from the same as a negative electrode active material. According to the present invention, since an intermediate prepared by adding a polyhedral oligomeric silsesquioxane (POSS) to a reaction mixture for preparing silicon oxycarbide, which is composed of a polysiloxane polymer and an aromatic compound, is pyrolyzed to prepare porous silicon oxycarbide (SiOC), although the content of a free carbon region is lower compared to conventional silicon oxycarbide, the cage structure of the POSS is maintained in the pyrolysis to form many pores uniformly distributed in the SiOC matrix, and thus rapid diffusion of electrolyte ions is possible, and because the contents of SiO3C and SiO2C2 in the SiOC matrix are increased, a reversible capacity in the Si—O—C phase can be enhanced.
