Soft package battery cell secondary processing area method capable of directionally exhausting air and mold for soft package battery cell secondary processing area method

The invention relates to the technical field of soft package battery processing, and discloses a soft package battery cell secondary processing area method and a mould capable of directionally exhausting, a thermal packaging mode is adopted, primary processing of a packaging structure including an aluminum plastic film is completed, and a first thermal sealing area located at the top end of a soft package battery cell and second thermal sealing areas located on the two sides of the soft package battery cell are formed; determining the heat-sealing strength standard of a first-time processed product as a basic standard; and selecting a special area in the first heat sealing area as a secondary processing area, and processing the secondary processing area by adopting heat sealing strength which is 15-20% higher than the basic standard, so that the strength of the secondary processing area is lower than that of other areas, and an exhaust port is formed during thermal runaway. According to the invention, through
