Problems solved by technology

First of all, the above-mentioned connection method using conductive strips is not carried out until the battery pack is manufactured and put into assembly, which not only adds to the process flow, but also makes it difficult to ensure the reliability of the battery pack.
Moreover, due to the complex process, the requirements for assemblers are further increased, thereby reducing production efficiency

Abstract

The invention provides a battery pack, a manufacturing method of the battery pack, a battery and an electronic device. The battery pack comprises an external package and a battery unit, wherein the external package is of a stacked type, and the external package is internally provided with a conducting layer; the battery unit is provided with a positive pole end and a negative pole end which are held in the external package, and the part of the positive pole end or the negative pole end of the battery unit, which is led out from the external package, is electrically connected with the conducting layer. With the adoption of the battery pack and the manufacturing method of the battery pack, the influence of electrostatic discharge can be eliminated through a simple structure.

Description

technical field [0001] The present invention relates to a battery pack used in batteries for electronic devices, and more particularly to a battery pack capable of eliminating the influence of electrostatic discharge, a method for manufacturing the battery pack, a battery incorporating the battery pack, and an electronic device incorporating the battery. Background technique [0002] In recent years, battery packs have been used as power sources for mobile electronic devices. In such a battery pack, the outer package accommodates the battery cells and a protection circuit board on which a protection circuit and the like are mounted. As an outer package used for such a battery pack, a cassette-type package including upper and lower cases and the like is widely used. [0003] However, in the above-mentioned battery pack, when electrostatic discharge (ESD) occurs, static electricity may flow in a circuit board inside the battery pack, causing malfunction of an electronic circu...
