Battery comprising soft packaged battery core

Abstract

The invention discloses a battery comprising a soft packaged battery core. The battery comprises the soft packaged battery core, an electromagnetic shielding piece and a lower cover, the soft packagedbattery core comprises a soft packaged battery core body, a first electrode tab and a second electrode tab, the first electrode tab and the second electrode tab are located on the periphery of the soft packaged battery core body, and the free ends of the first electrode tab and the second electrode tab extend outward; the electromagnetic shielding piece adheres to the upper surface of the soft packaged battery core body, the first electrode tab and the second electrode tab are bent and extend to the position above the upper surface of the electromagnetic shielding piece, the bottom of the soft packaged battery core body adheres to the bottom surface of the inner side of the lower cover, and the electromagnetic shielding piece and the lower cover are filled with plastic injection layers. The battery comprising the soft packaged battery core, the generation of an electromagnetic interference signal is reduced by using the battery comprising the soft packaged battery core, and electromagnetic interference generated from a product adopting the battery is reduced, and the product quality and the using experience of a user are improved; the risk of leakage of electrolyte can be avoided,and hidden safety danger such as short circuit of the battery and the like is reduced.

Description

technical field [0001] The invention relates to a battery, in particular to a battery containing a soft battery core. 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 ...
