Problems solved by technology

[0002] Some existing button batteries have 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 safety accident occurred
When the existing soft-pack battery is used in headphone audio wearable products, it will cause electromagnetic interference to the product using the battery, reducing product quality and user experience

Abstract

The invention discloses a battery comprising a soft package battery cell. The battery comprises the soft package battery cell and an electromagnetic shielding piece made of an electromagnetic shielding material. The soft package battery cell comprises a soft package battery cell body, a first pole lug and a second pole lug. The electromagnetic shielding piece is arranged on the soft package battery cell body in a surrounding mode, and an end of the first pole lug and an end of the second pole lug are located at the periphery of the soft package battery cell body, and the free end of the firstpole lug and the free end of the second pole lug extend outwards from the electromagnetic shielding piece. According to the battery comprising the soft package battery cell, the risks of electrolyte leakage and short circuit in the soft package battery cell body are reduced; the electromagnetic interference signals are reduced, so no electromagnetic interference is generated to a product using thebattery, and the quality of the battery and the use experience of a user are improved.

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. When the existing soft-pack batteries are used in earphone audio wearable products, electromagnetic interference will be generated to the products using the batteries, which will reduce product quality and user experience.
