PURPOSE: A manufacturing method of carbon/silicon multi-core microparticles is provided to enhance electrical reliability by solving expansion problems during the time of charging and discharging when using a silicon group composite as an anodal active material. CONSTITUTION: A manufacturing method of carbon/silicon multi-core microparticles comprises the following steps. A monemeric compound and a volatile organic solvent are mixed, and the monomeric compound is polymerized to form a macromolecular solution. Si nano particles are added to the macromolecular solution. The Si nano particles added to the macromolecular solution are mixed with water to form oil in a water composition. The volatile organic solvent is evaporated from the oil in water composition, and forms solid phase particles. The solid phase particles are carbonized to obtain the carbon/silicon multi-core microparticles.
