With the novel angle envelope end enclosure structure proposing a kind of polymer soft bag lithium ionic cell, it uses
It is unencapsulated that battery bottom reserves 1～5mm region flanging, can effectively prevent battery bottom aluminum
Plastic film fold position forms cusp；Its battery product quality is made to be greatly improved.
For realizing this technical purpose, the technical solution adopted in the utility model is: a kind of polymer
The angle envelope end enclosure structure of soft bag lithium ionic cell, including end socket main body, described end socket main body includes
Upper cover and low head, and upper cover and low head be symmetrical arranged about battery angle envelope；Under described
End socket upper end offers step, and shoulder height is 0.15mm；Described battery angle envelope is a length of
7mm, and battery angle envelope the length upper deviation be+3mm, battery angle seal length lower deviation be-3mm.
Further, described length of bench is 1～5mm.
Further, envelope thickness in described battery angle is 260um～300um.
Further, at described upper cover and low head end socket, length is equal.
Compared with prior art, this utility model has the advantages that this polymer Soft Roll
The angle envelope end enclosure structure of lithium ion battery, it uses and is provided with a step on low head, makes
It is unencapsulated that it reserves 1～5mm region flanging at battery bottom, can effectively prevent battery floor
Aluminum plastic film fold position, portion forms cusp, will not produce when bending aluminum plastic film in actual production process
Stress is concentrated, and the flex life intensity improving aluminum plastic film is the most damaged to more than 25 times, thoroughly solves
The problem that certainly polymer soft bag lithium ionic cell R angle is damaged, it is ensured that polymer Soft Roll lithium-ion electric
Pond encapsulation quality；Simple to operate, practical, it is easy to promote the use of.
