Embodiment Construction

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application.

[0054] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

[0055] Unless otherwise defined, all technical and scientific terms...

Abstract

The invention provides a battery. The battery comprises a packaging bag, an electrode assembly, an adapter and a sealing element, wherein the electrode assembly is arranged in the packaging bag. The electrode assembly comprises a first pole piece and a first tab, and the first tab is electrically connected with the first pole piece. The first end of the adapter is connected with the first tab, and the second end of the adapter extends out of the packaging bag. And the sealing element is arranged between the adapter piece and the packaging bag. In the width direction of the battery, the width of the first tab is greater than or equal to that of the sealing element. According to the battery, the size relationship between the first tab and the sealing element is improved, so the sealing element can be effectively prevented from puncturing the pole piece in the falling process of the battery, and the falling performance of the battery is simply and effectively improved while the energy density and the production process of the battery are not influenced.

Description

technical field [0001] The present application relates to a battery. Background technique [0002] When the battery is dropped, the electrode assembly placed in the battery packaging bag is easily impacted, causing the sealing structure on the packaging bag to pierce the pole piece, which in turn leads to an internal short circuit of the electrode assembly. In the existing design, insulating glue is attached to the electrode assembly to solve the internal short circuit problem during the drop process. However, the setting of the insulating glue will reduce the energy density of the battery, and at the same time, the process of attaching the insulating glue will also increase the production process, thereby affecting the production efficiency. Contents of the invention [0003] In view of the above situation, the present application provides a battery. By improving the dimensional relationship between the first tab and the sealing member, it can effectively prevent the sea...
