POROUS CARBON STRUCTURE, MANUFACTURING METHOD THEREFOR, AND LITHIUM SECONDARY BATTERY COMPRISING SAME

The present disclosure relates to a porous carbon structure and a manufacturing method therefor. More specifically, the porous carbon structure comprises a core-shell structured MOF, in which a first MOF contained in a core and a second MOF contained in a shell have different porous structures and constituent elements, and thus when applied as a sulfur support in a lithium secondary battery containing sulfur as a cathode active material, the core-shell structured MOF can prevent polysulfides generated from an anode from being released into an electrolyte, thereby improving performance and lifespan characteristics of the battery.
