POUCH-TYPE SECONDARY BATTERY HAVING INCREASED ENERGY DENSITY, AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to a pouch-type secondary battery and a method for manufacturing same, the pouch-type secondary battery comprising: a stacked electrode assembly in which one or more intermediate assemblies are stacked; and a case which accommodates the stacked electrode assembly, and the center part of which has a larger width than the upper and lower surfaces, thereby having high capacity and facilitating dissipation of internal heat.
