a lithium battery

Abstract

The invention discloses a lithium battery, which comprises an electrical core, the electrical core comprises a positive electrode plate, and a negative electrode plate and a diaphragm, the positive electrode plate is provided with a positive electrode ear, the negative electrode plate is provided with a negative electrode ear, the electrical core is an arc plate structure, the electrical core is provided with two opposite long side edges and two opposite short side edges, the long side edges are arc-shaped, the positive electrode ear and the negative electrode ear are respectively arranged on the two opposite short side edges, the positive electrode ear is provided with a nickel belt, the positive electrode ear is sheathed with a heat shrinkable sleeve, and the nickel belt is arranged between the positive electrode ear and the heat shrinkable sleeve and is arranged beyond the heat shrinkable sleeve. The electrical core is made into the arc plate structure, so that the electrical core can cater wearable electronic products in ring structures, the electrical core damage and electrode ear fracture caused by continuous repeated bending adjusting of the electrical core during the installation process can be prevented, adjustment is easy, the positive electrode ear and the negative electrode ear are respectively arranged on different short side edges, the difficulty of processing is reduced, the short-circuit problem caused by too small spacing between the positive electrode ear and the negative electrode ear can be solved, the nickel belt is used for tin soldering in welding of a protection board, and the heat shrinkable sleeve is used for strengthening the folding resistant strength of the positive electrode ear.

Description

Technical field [0001] The invention relates to a lithium battery. Background technique [0002] There are various signs such as the new product launch of Google Glass and the upcoming launch of Apple's iWatch smart watch, which indicate that wearable electronic products may set off the next wave of new technology. The power supply problem of such products is an important limiting factor in the development of wearable electronic products. This type of product requires lightweight batteries, good safety performance, large battery capacity, and long cycle life. Lithium polymer batteries are lighter in weight. Since wearable electronic products are often shaped like a ring structure, existing batteries are being adjusted to suit The ring structure is often easily damaged during the process. Contents of the invention [0003] The problem to be solved by the present invention is to provide a lithium battery that caters to wearable electronic products with a ring structure and ...

AI Technical Summary

Problems solved by technology

The battery cell is made into an arc-shaped plate structure so that the battery cell caters to the wearable electronic products with a ring structure, and prevents the battery cell from being repeatedly bent and adjusted during the installation process, resulting in damage to the battery cell and breakage of the tab. It is easy to adjust, and the positive pole The tabs and the negative tabs are arranged on different short sides, and the distance between the positive and negative tabs is increased as much as possible under the limitation of the size of the battery cell, which reduces the difficulty of processing and solves the problem of short circuit caused by too small spacing between the positive and negative tabs. The problem is to set the nickel strip on the positive tab for soldering the protective plate, and put a heat shrinkable sleeve on the positive tab to strengthen the folding strength of the positive tab
