With the continuous development of capacitor industry，the manufacturing technology of the drawing and coating of the localized polypropylene film is also undergoing rapid progress and its performance data has reached the advanced level in the world，which provides the support of raw material for the high energy density pulse capacitor based on localized metallized film. In order to develop high energy storage density pulse capacitor based on the localized metallized film，such key technologies as selection of working field strength，design of improving durability performance，design of internal structure of the product and the safety design of the capacitor are studied in accordance with the technical data of the capacitor. The elements of and sample of the capacitor are verified by test，and the pulse capacitor with an energy storage density at 0.8 kJ/L，charge and discharge energy up to 156 kJ and and the charge and discharge life up to 50 000 times is developed successfully. This paper provides exploration idea for the design and manufacturing of the localized high energy storage density pulse capacitor with localized metallized flim.
