Abstract
The present invention relates to a method for manufacturing a carbon-sulfur composite, a carbon-sulfur composite manufactured by the method, and an electrochemical device including the same. Since the carbon-sulfur composite manufactured by the carbon-sulfur composite manufacturing method of the present invention includes the hollow carbon ball having the inner hollow which is uniformly filled with sulfur, a sulfur content increases to increase a capacity characteristic increases. In addition, even though sulfur is changed into a liquid state during charge and discharge processes, an electrode structure is not destroyed to realize a stable lifetime characteristic.
