Description

Technical Field

[0001] The utility model relates to the technical field of battery electrode structures, in particular to an electrode structure for a battery. Background Art

[0002] A battery is a device for energy conversion and storage. It converts chemical energy or physical energy into electrical energy through chemical reactions. A battery is usually composed of a positive electrode, a negative electrode, an electrolyte, and a container or a diaphragm. Its working principle is to store and release electrical energy through the redox reaction between the positive and negative electrodes. According to the working principle, batteries can be divided into various types such as primary batteries, storage batteries, fuel cells and solar cells. They have broad application prospects. Batteries play an important role in modern society and are widely used in various electronic devices, transportation vehicles, energy storage and other fields. Based on the key role played by electrodes in batteries, batteries need to use electrode structures. Electrodes are the basic components of batteries. Positive and negative electrodes play a vital role in batteries.

[0003] The existing electrode structure has only one hole, which can easily cause poor stability of the battery during use, which is not conducive to improving the service life and reliability of the battery cell. At the same time, the electrode structure is assembled by welding or force sealing. The welding and fixing method allows only wire sealing between the electrode structures. The wire sealing is completely dependent on the reliability of welding, which is prone to leakage points, thereby affecting the reliability of the electrode. Utility Model Content
