Battery containing soft package battery cell

Abstract

The invention discloses a battery containing a soft package battery cell. The battery comprises an upper cover, a soft package battery core and a lower cover. The bottom of the upper cover is clampedto the upper portion of the lower cover in a sealed mode. An accommodating cavity is formed between the upper cover and the lower cover, and the soft package battery cell is located in the accommodating cavity, wherein the soft package battery cell comprises a soft package battery cell body, a first electrode lug and a second electrode lug, and the first electrode lug and the second electrode lugare located in the middle of the soft package battery cell body, and the free ends of the first electrode lug and the second electrode lug extend outwards. The first electrode lug is fixedly connectedwith the upper cover or the lower cover, and the second electrode lug is fixedly connected with the lower cover or the upper cover. According to the invention, the battery containing the soft packagebattery cell reduces the corrosion problem of the upper cover and the lower cover and the risk of electrolyte leakage of the battery, prolongs the service life, improves the safety of the battery, cannot generate an electromagnetic interference signal, cannot generate electromagnetic interference to a product using the battery, and improves the product quality and the 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 ...
