Method for Manufacturing Pouch Case of Secondary Battery, and Pouch Film of Secondary Battery and Pouch Case of Secondary Battery - A simplified explanation of the abstract
This abstract first appeared for US patent application 18032951 titled 'Method for Manufacturing Pouch Case of Secondary Battery, and Pouch Film of Secondary Battery and Pouch Case of Secondary Battery
Simplified Explanation
The patent application describes a method for manufacturing a pouch case for a secondary battery. The method involves measuring the elongation rate of a pouch film without the need for separate sampling. The elongation rate is determined by the color of the outer layer of the pouch film.
- The method involves stacking a metal layer above an inner layer and then stacking an outer layer with colored dye particles above the metal layer to create a pouch film.
- The pouch film is then formed into a three-dimensional shape to accommodate an electrode assembly.
- The elongation rate of the pouch film is measured by analyzing the color of the outer layer.
- This measurement helps determine if the elongation has reached critical levels where a crack is about to occur or if it has already reached a defective level where a crack is occurring.
Original Abstract Submitted
During a process of manufacturing a pouch case by forming a pouch film, an elongation rate can be measured by the color of an outer layer of the pouch film without separate sampling, and it can be determined whether or not elongation has occurred which causes a critical level in which a crack is about to occur or a defective level in which a crack is occurring. A method for manufacturing a pouch case of a secondary battery according to the present invention includes: stacking a metal layer above an inner layer and stacking an outer layer, which includes colored dye particles, above the metal layer, thereby producing a pouch film; forming the pouch film into a three-dimensional shape so that an electrode assembly is accommodated therein; and measuring an elongation rate of the pouch film through color of the outer layer.
