    Abstract: A method for manufacturing a hollow carbon sphere according to an embodiment of the present invention comprises the process of manufacturing a hollow carbon sphere with micropores using a material including template particles and metal-phthalocyanine. A carbon shell-sulfur composite can be manufactured by embedding sulfur inside the hollow carbon sphere and the manufactured hollow carbon sphere can be used as the cathode material of a lithium-sulfur secondary battery as the manufactured hollow carbon sphere has a carbon wall surface with micropores. The carbon-sulfur composite material manufactured according to the method can increase the very low electroconductivity of sulfur, can prevent lithium polysulfide with a long chain structure from being dissolved in electrolyte by confining sulfur and lithium polysulfide, which is derived from sulfur, inside a carbon shell having micropores distributed thereon, can minimize shuttle reaction, can reduce an overcharging amount between charge and discharge, and can improve the performance of a secondary battery. Moreover, the present invention provides a method for mass-producing the hollow carbon spheres and the carbon shell-sulfur composite.
