Soft cell-packaged battery

Abstract

The invention discloses a soft cell-packaged battery. The soft cell-packaged battery comprises an upper cover, a soft cell, a lower cover and a support, wherein the soft cell-packaged battery comprises a soft cell body, a first lead and a second lead, the end portions of the first lead and the second lead are arranged on the lower portion of the circumference of the soft cell body, and the free ends of the end portions of the first lead and the second lead extend outwards; the soft cell package is arranged inside the support, the free end of the first lead is fixedly connected to the upper cover or the lower cover, the free end of the second lead is fixedly connected with the lower cover or the upper cover, the upper cover is fixedly connected in a sealed mode to the top of the support, the support is arranged inside the lower cover, and the upper end of the circumference of the lower cover abuts against the outer circumferential wall of the upper end of the support. The soft cell-packaged battery reduces the risks of corrosion of the upper cover and the lower cover as well as leakage of electrolytes, prolongs the service life and meanwhile avoids potential risks of short circuit,thereby improving safety, avoiding producing electromagnetic interference signals, avoiding electromagnetic interference to products applying the soft cell-packaged battery, and further improving theproduct quality and user experience.

Description

technical field [0001] The invention relates to a battery, in particular to a battery containing a soft battery cell. Background technique [0002] Some existing button batteries have an electrolyte in the steel shell, and its structure has the risk of leakage, and the electrolyte may corrode the steel shell, resulting in thinning of the steel shell and leakage, reducing safety. There is a risk of short circuit inside this type of battery, which will cause the battery to bulge, expand, heat, etc. Since this type of battery is often used in wearable products such as earphones, which are in direct contact with the human body, once the above phenomenon occurs, it will often cause great harm to the human body , a security incident occurs. [0003] At the same time, the shape of the existing soft-pack batteries is not fixed, it is difficult to standardize the assembly in a small space, and the space utilization rate is low. Generate electromagnetic interference, reduce product ...
